AMESim和ADAMS联合仿真设置

AMESim和ADAMS联合仿真设置amesim和ａｄａｍｓ依靠AMESIM7 0和亚当斯2022或2022。

除这两个软件外，还应安装完整版本的VC++（请注意，不应使用绿色版本，但应使用完整破解版本）。

设置环境变量：右键单击我的电脑>属性>高级>环境变量，单击管理的用户变量列下的“新建”，然后设置：变量名ame_adams_home变量值填充在安装Adams的安装路径中（例如：D:\\adams2022）然后确定。

在开始>运行栏中打cmd进入dos环境，输入echo%ame_adams_home%请注意，echo后面有一个空格，然后按enter键以显示您的Adams安装路径（例如：D:\\Adams 2022）。

描述是正确的。

下面总体说一下联合仿真过程，简单的说，是两种软件量与量的交换过程。

首先在adams中会建立一个接受amesim传来的量（f）驱动模型，然后从adams中输出一个模型量（w）传到amesim。

建立Adams模型：首先建立一个工作文件夹，adams和amesim的工作目录全部指向它，注意这个文件夹的名字和路径全部为英文不能有其他符号和字符，视频教程中建在c盘根目录下，命名aa。

为了说明清楚，在这里仅建立了一个绕固定点旋转的杆件模型，在它和ground直接加入铰接关系，就是那个合页的连接关系，给它加入空间力矩。

然后在build下选systemelements>stablevariable>new建立新的变量（famesim输入扭矩），用同样的方法建立变量w（adams输出角速度），并且设置w的值，从build下选systemelements>stablevariable>modify选择model中的w，设定f=值，点击三个小点的按钮进入functionbuild，在下拉框中选择velocity，单击anglarvelocityaboutz，点击assist，在tomarker栏右键单击，选择marker>browse,选择part2cm（杆中心点），ok，ok，删掉原有的0，然后确定，然后选择build>ContralLight>plantinput。

AMESim与ADAMS联合仿真操作说明

AMESim与ADAMS联合仿真操作说明摘要：物理系统可能由各种元件组成，例如气动的，机械的，液压的，电子的以及控制系统等，所有的元件协同工作。

多学科领域系统和复杂多体系统之间的相互作用很难在单一的软件平台中来仿真。

解决的方案就是通过AMESim和专用的多体动力学软件ADAMS之间的接口，使得两者在仿真中协同工作。

本文结合天线的简单实例介绍AMESim与ADAMS联合仿真的操作过程。

关键词：AMESim ADAMS 联合仿真1.引言AMESim（Advanced Modeling Environment for Simulation of engineering systems）软件是由法国IMAGINE公司于1995年推出的多学科复杂领域系统工程高级建模和仿真平台，该软件不要求用户具备完备的仿真专业知识，采用面向系统原理图建模的方法，便于工程技术人员掌握和使用。

机构动力学分析软件ADAMS (automatic dynamic of mechanical system)集建模、求解和可视化技术于一体,能有效分析和比较多种参数方案。

运用AMESim与ADAMS的联合仿真，可以有效的对设备的动态过程进行分析，根据交互分析产生的结果来评价设备的性能，为了更加真实的符合实际情况，理论分析用来完成检验产生的数值结果。

这种虚拟产品开发方法与得出的结论将对设计人员提供一定帮助。

通过AMESim/ADAMS之间的接口，有两种方式实现联合仿真：（1）将模型从一个平台中输入到另一个平台中，采用单一的积分器进行计算。

（2）各个平台分别利用自己的积分器计算自己的模型，通过预先统一的通讯间隔进行信息交换。

2.软件环境要求首先AMESim软件需要4.2级以上版本； ADAMS需要2003级以上版本（含A/Control模块）。

其次必须要有Microsoft Visual C++ 编译器。

如果需要从ADAMS环境中使用接口，那么还强烈推荐Fortran编译器，这样可以将AMESim的模型编译成为ADAMS的子函数（Subroutine）。

Amesim 和 Adams联合仿真设置过程和关键点

高版本的Adams已经不再支持Adams导入Amesim这种联合模式（以Amesim 作为master的co-simulation也不行），但是将Amesim导入Adams或者以Adams 作为master的co-simulation还是没有问题的。

下表是兼容性对比图表（来自Amesim的help文档）：下面讲述的过程是基于Amesim R13 、Adams 2012和VS 2009（32-bit）：1、安装软件最好的安装顺序:VS , Adams，Amesim安装路径不要有中文和空格及特殊字符2、环境变量设置AME_ADAMS_HOME，指向Adams安装目录，如：D:\MSC.Software\MD_Adams\R3 ADAMS_CONTROLS_WTIME＝203、安装完成后，确认在AMESim安装目录下（如：AMESim/v1300）已包含如下文件：nmake.exevcvars32.bat如果没有，从VS安装目录拷贝过来。

3、将adams库加入到Amesim路径中：完成之后在你的Amesim库列表中包含Import of Adams models库：4、以下以Amesim之中help自带的例子讲述联合仿真操作过程（简单、方便联合仿真调通）将例子拷贝到某个目录下，用Amesim打开.ame文件，编译器选择VC++编译，确保在同一个目录下生成了.dll文件：5、打开adams，设置路径(Select Directory…)到.ame文件所在位置（这步很关键，如果不选可能会出错）6、导入Adams的cmd格式文件，一般在%AME%\v1300\demo\Platform\1D3DCAE\MBS\AMESimAdams,如：D:\AMESim\v1300\demo\Platform\1D3DCAE\MBS\AMESimAdams7、选择solver：为了方便在仿真时看结果，可以选择Display,在Show Messages 后面选择Yes再选择编译器和dll文件，Executable 下拉菜单选择External;Solver Library 后面灰色出双击鼠标左键，找到.ame文件生成的.dll文件在Choice后面选择C++作为编译器此处有建议选择FORTRAN的，我的Fortran版本太低，当时无法计算；不过选择C++就能正常计算，一般情况也不需要再安装Fortran。

Matlab Amesim Adams联合仿真

联合仿真可以充分利用各仿真软件的优点，从而简化建模实现快速仿真。

这里首先讲下如何实现联合仿真，工欲善其事，必先利其器。

一.Matlab与Amesim1. 安装好matlab与amesim。

要点：安装目录不要有空格，比如不要放到program files这个目录中。

2.安装编译器(compiler)Microsoft Visual C++ 6.0（必须）或者Compaq Visual Fortran Pro v6.6.0（可选），在安装过程中遇到设置环境变量的(environmental variance)选择‘yes’，免得以后自己添加麻烦3.拷贝Microsoft Visual C++ 6.0安装目录下\VC98\Bin\VCVARS32.BAT文件到Amesim的安装目录下。

比如：C:\Program Files\Microsoft Visual Studio\VC98\Bin中的VCVARS32.BAT拷贝到C:\AMESim\7.0.0下面4.设置Matlab环境变量，这样联合仿真时Amesim才能找到matlab。

在系统变量中添加‘MATLAB’，其值为Matlab的安装路径，如D:\MATLAB\R2009a。

5.在matlab中设置编译器（如下图）。

在matlab命令行里输入mex -setup，选择编译器Microsoft Visual C++6.0 ,最后选Y确定。

6. 在Amesim里选择编译器。

打开Amesim--tools--options--Amesim preferences选择Microsoft Visual C++7.在Matlab 的目录列表里加上AMESim与Matlab 接口文件所在的目录%AME%\matlab\amesim,其中%AME%是AMESim的安装目录,如果安装在C:\AMEsim ,则就加上C:\AMEsim\matlab\amesim。

（有的版本这个目录可能是安装目录\******ing\matlab\amesim）8．在matlab中set path中继续添加路径：%AME%\7.0.0\interface\simulink以及%AME%\7.0.0\interface\sl2ame9. 完成，实现amesim to simulink 和simulink to amesim 的联合仿真。

基于ADAMS和AMESim联合仿真的压力机平衡缸优化设计

基于ADAMS和AMESim联合仿真的压力机平衡缸优化设计杜二虎;莫健华;吕言;黄海波【摘要】In order to simulate and optimize the balance cylinder system precisely,the simulation and optimal design method based on ADAMS and AMESim co -simulation has been proposed in the text.The mechanical dynamic system of the model has been built on ADAMS platform,while the hydraulic,pneumatic and control systems of the model have been built on AMESim platform.Then,a co-simulation of the transmission and balance cylinder system for the servo press has been carried out by use of two kinds of software.It is found out that proper increase of the hose diameter and the accumulator volume of the hydraulic system can apparently reduce the load of the motor.%平衡缸是机械式压力机必不可少的一部分,平衡缸系统的设计涉及到机、电、液、气诸方面.本文应用基于ADAMS和AMESim联合仿真的仿真与设计方法,即利用ADAMS建立平衡缸系统的机械动力学模型,利用AMESim建立平衡缸系统的液压、气动模型以及控制系统.然后利用两个软件对伺服压力机传动系统及平衡缸系统进行联合仿真,得出适当增加平衡缸液压系统软管直径和蓄能器容积可以明显减小电机负载.【期刊名称】《锻压装备与制造技术》【年(卷),期】2012(047)003【总页数】4页(P26-29)【关键词】机械设计;平衡缸;联合仿真;ADAMS;AMESim;伺服压力机【作者】杜二虎;莫健华;吕言;黄海波【作者单位】华中科技大学材料成形与模具技术国家重点实验室,湖北武汉430074;华中科技大学材料成形与模具技术国家重点实验室,湖北武汉430074;华中科技大学材料成形与模具技术国家重点实验室,湖北武汉430074;华中科技大学材料成形与模具技术国家重点实验室,湖北武汉430074【正文语种】中文【中图分类】TG315.5机械式伺服压力机拥有高精度、高柔性、低能耗以及高效率等优点。

AMESim与ADAMS联合仿真步骤及相关注意事项

AMESim与ADAMS联合仿真1、安装软件最好的安装顺序:VS , Adams，Amesim安装路径不要有中文和空格及特殊字符2、环境变量设置AME_ADAMS_HOME，指向Adams安装目录，如：D:\MSC.Software\MD_Adams\R3ADAMS_CONTROLS_WTIME＝203、安装完成后，确认在AMESim安装目录下（如：AMESim/v1300）已包含如下文件：nmake.exevcvars32.bat如果没有，从VS安装目录拷贝过来（C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin）。

4、将adams库加入到AMESim路径中：五、如果提示MSSDK问题，安装GRMSDKX_EN_DVD.iso。

也就是安装Windows SDK7.1如果安装时报错，可按照方法：卸载比Microsoft Visual C++ 2010 x86 Redistributable - 10.0.30319 以及Microsoft Visual C++ 2010 x64 Redistributable - 10.0.30319更高的版本。

如果还出错，在安装时不要选择安装VC-Compiler，其它选项默认即可。

如果卸载了上面的两个组件，则需要安装VBVCRedist中的两个补丁，只需要选择两个卸载的补丁即可。

六、如果提示AsUtility_imp.lib的link错误，在C盘中搜索，找到该文件，再放到AMESim 模型所在工作目录。

(一般不需要此项。

)七、64位操作系统中：AMESim中选择Microsoft Visual C++编译器，Subplatform type选择win64。

如下图八、接口类型为ADAMS还是AdamsCosim，决定于是用离散耦合，还是连续的。

Adams or AdamsCosim depending whether you want to run discrete coupling or continuous export选择AdamsCosim则adams中应该为Discrete。

基于Adams与Amesim的二维精密高速转台机电联合仿真分析

M g=[m×(a2+b2)/12+m×r2]×α=［3000×（2.42+0.842）/12+3000×0.12］×0.042=69.1 (N⋅m)（5）转盘轴承的摩擦力矩根据经验估算为：M Q= 50 N⋅m.需要启动力矩：M′=M f+M g+M Q=513+69.1+50=632.1 (N⋅m)（6）要得到电机输出转矩，还需要计算转盘轴承到电机的减速比.驱动齿轮与转盘轴承之间的减速比为i方1=Z1/Z2=125/20；减速器的减速比为i方2=60；总的减速比为：i方=i方1×i方2=375.在载荷计算中方位传动座的启动力矩为632.1 N⋅m，取安全系数1.3，电机输出力矩至少大于632.1×1.3/375=2.19 N⋅m.取电机输出轴力矩大小为2.2 N⋅m.2.3　仿真分析验证建立的动力学仿真模型，测试方位转台旋转60°和120°的驻留情况.由启动期间的加速度大小，计算得到两种情况的运转时间分别为7.071 s和10 s，且未达到额定转速，处于加速阶段，在转盘轴承上添加marker点，测试该点的旋转角度，将方位电机输出力矩大小设置为2.2 N⋅m，在Adams软件里进行仿真，如图4和图5所示.Adams软件里角度单位默认是弧度.经计算，实际旋转角度分别为58.99°和 118.65°，驻留角度相对误差为1.68%和1.13%.由于添加接触力，运动时各零件之间存在阻力，旋转角度偏小，且在实际运动情况中，驻留需要加速阶段和减速阶段，因此只使用Adams软件很难反映传动座实际运行情况，下文将加入Amesim软件进行联合仿真.表1　模型约束Tab.1　Model

Adams和AMESim联合仿真的设置和简单例子(都是13版本)

Adams和AMESim的联合仿真前言：本人并不是Adams和AMESim的高手，接触AMESim的时间很短，但是需要做Adams和AMEsim的联合仿真，这里分享一下我探索联合仿真的经验。

目录如下：一、仿真前需要做的准备。

1、软件的安装2、环境变量的设置二、一个具体的联合仿真例子。

（这里只介绍Adams主控的仿真）***********************************************************一、仿真前的准备1、软件的安装软件的版本对联合仿真有重要影响，这里只介绍我自己安装软件的情况。

我的系统是win7 32位，安装的软件是Adams2013、LMS b AMESim Rev 13、Visual Studio 2010。

Adams2013和AMESim Rev 13网上有很多下载资源和安装教程。

这里我只强调一下Visual Studio 2010。

也就是可以建立两个仿真软件联系的Visual C++程序。

Visual C++和VisualStudio等之间的关系大家可以自己在网上查，其实都包含有C++语言。

网上有些教程是用VC++6.0来建立两者之间的关系，但是我安装了VC++6.0的各种版本（企业版，中文版，英文版）都没有成功建立仿真，后来安装了完整的Visual Studio 2010就可以了，但是Visual Studio 2010有些大，我下载的是1.75G。

另外就是安装顺序，最好先安装VC++或者VS（我是最后安装的Visual Studio 2010，先安装的说法我这里并没有证实）。

下面是我的软件的安装位置，安装目录没有中文D:\zy\ADAMSD:\AMESimD:\Program Files\Microsoft Visual Studio 10.0在最后安装好Visual Studio 10后把D:\ProgramFiles\Microsoft Visual Studio 10.0\VC\bin下的nmake和vcvars32文件拷贝到AMESim的安装目录下D:\AMESim\v1300。

IntroductionThe AMESim ADAMS interface enables you to link an AMESim model with an ADAMS multibody model of a mechanical structure. By coupling motion simulation and system simulation, this interface improves the accuracy of your full system simulation.This interface is useful when hydraulic or pneumatic fluid power systems or other AMESim systems interact with complex mechanical structures.The interface is designed so that you can continue to use many of the AMESim facilities while the model is running in ADAMS. In particular, you can change the parameters of the AMESim model within AMESim in the normal way and monitor the results by creating plots just as if you were producing a regular run.Normally you will have AMESim and ADAMS running simultaneously so that you can use the full facilities of both packages. An illustration of this process follows:When the process is finished, the user can change the AMESim model parameters within AMESim, as well as the ADAMS parameters within ADAMS.1.1. Organization of this manualThis manual describes both the two-way full export interface (using ADAMS or AMESim integrator exclusively for the full system) and the two-way co-simulation interface (where both solvers are used, one of them being called by the other).The main part of the manual deals with the standard interface and section 5 looks at the differences between export and co-simulation.The structure of this manual is the following:•Section 1 is the current section.• Section 2: Preliminaries, describes how you must set your working environment so that you can use the interface.• Section 3:Error! Reference source not found. describes how ADAMS imports the AMESim model.2. Section 4: Importing Adams into AMESim•, uses a simple example to describe how to create an AMESim model and configure it to run in cooperation with ADAMS.•Section 5: This section describes the differences between co-simulation interface and the export facility.• Section 6: Tips on using the interface, gives some advice on efficient use of the interface.• Section 7: Advanced use of the interface and Section 8: Advanced configuration of the interface, are useful for customized use of the interface (advanced users). Sometimes a section of text is only valid for a UNIX or Linux environment, for such text, the following presentation is used:Using UNIX:Description for Unix/Linux based environments.Similarly, sometimes a section of text is only valid for a Windows environment, for such text, the following presentation is used:Using Windows:Description for Windows based environments.We assume that either the reader of this manual is already familiar with using AMESim and ADAMS or an AMESim user and an ADAMS user will collaborate in performing the task.We recommend that new AMESim users at least do the tutorial examples in the AMESim manual before attempting a combined simulation. Similarly, a new ADAMS user should become familiar with using ADAMS before attempting a combined simulation.3. Preliminaries3.1. License requirementsWhen the user is running a coupled simulation from the AMESim environment, an Adams interface license is required in AMESim in combination with a standard AMESim runtime license. On the ADAMS side the module Adams/Controls (A/Controls) is needed.When running simulations from ADAMS the user only needs Adams interface and AMESim runtime licenses, A/Controls is unused.3.2. Compiler requirements3.2.1. Requirements to import ADAMS model into AMESimUsing Unix:You will need an ANSI C compiler.Using Windows:You must have at least Microsoft Visual C/C++ 6.0, .NET 2003, 2005.3.2.2. Requirements to export AMESim models into ADAMS AMESim follows the requirements given for ADAMS 2005Software specifications are:Hardware Vendor OperatingSystem Fortran C/C++Intel andIntel- compatible PCs Windows 2000,Windows XPProfessionalCompaq VisualFortran 6.6BMS Visual C/C++ 6.0 (SP5)orVisual Studio C++.NET 2003c89 11.01.20aC++ 03.27Hewlett Packard HP-UX 11, 11i f90 2.4.13SGI IRIX6.5.14m7.3.1.2m 7.3.1.2mIBM AIX 4.3.3, 5.1*XL Fortran 7.1 Visual Age C/C++ 5.0.2Sun Microsystems Solaris 7, 8, 9 6 Update 16 Update 1* ADAMS Service Pack APN-130-257 is required to run on this operating system.3.3. Versions of ADAMS supportedThis manual applies to ADAMS 2005. The interface was developed using this version and when using a mode that requires A/Controls (i.e. importing into AMESim) we suggest that you use that version with following patches:A/View 2003 Service Pack 1 APN-130-240A/Solver 2003 Service Pack APN-130-252A/Controls 2003 Service Pack APN-130-256This manual was also revisited to add some particular aspects for using this interface with the Adams 2008 release3.4. Platforms supportedWindows (2000, XP), HP, Sun and IBM.3.5. Setting up the environmentIn order to use the AMESim / ADAMS interface it is necessary to set an environment variable that points to the ADAMS installation directory. If this is not set, AMESim will not be able to find the files necessary to compile the system.To find out if this environment variable is set, type the following line in a terminal window: Using Unix:echo $AME_ADAMS_HOMEThe result should be something like:/opt/Adams2005being printed on screen. If nothing is printed, or the message “AME_ADAMS_HOME: Undefined variable” is displayed, you must set this variable. To do this you need to know where ADAMS is installed. If your working environment is set up properly to run ADAMS, type either:which adams05 (if you are using C shell) or,whence adams05 (for Korn shell - ksh or Bourne shell - sh) or,type adams05 (for some versions of Bourne shells).This will tell you the location of the command to start ADAMS e.g./opt/bin/adams05Then type:l s –l /opt/bin/adams05This finds the link to the ADAMS directory, it may give something like:/opt/bin/adams05 Æ /opt/Adams2005/mdi*Remove the last part from this pathname to get the value to set for AME_ADAMS_HOME, in this case /opt/Adams2005. If you are using Unix C shell, you can then set the environment variable as follows:setenv AME_ADAMS_HOME /opt/Adams2005This statement can also be added to your .cshrc file so that the environment variable is set every time you log in.For Bourne or Korn shells the corresponding would be:AME_ADAMS_HOME=/opt/Adams2005; export AME_ADAMS_HOMEAdd these statements to your .profile file so that the environment variable is set every time you log in or add it to a script that launches AMESim .Using Windows:echo %AME_ADAMS_HOME%The result should be something like:C:\ADAMS2005being printed on screen. If the environment variable is not set, %AME_ADAMS_HOME% is printed and you need to set the environment variable to point to the ADAMS installation directory. This can be done from the Windows Control Panel.If you want to use this interface from ADAMS side, you will need a Fortran compiler as stated in section 2.2. Using Windows:In this case the file dfvars.bat must be copied into $AME. This file sets up the environment to use Fortran libraries.For Compaq Visual Fortran this file can be found here:C:\Program Files\Microsoft Visual Studio\DF98\BINCopy this file into the AMESim installation directory.Using Unix: You need access to a Fortran compiler. To be certain that the compiler is installed, type one of the following commands in a terminal window. For IBM type: xlf , for SGI type f77 and for Sun type f77. If the command issues an error message, please contact your system administrator.¾ In AMESim the $AME/libadams directory must be in the current path list.to 20.¾ AMS_HOME environment variable must be defined with a DOS-¾ the Visual C compiler, the make file called¾ n depending¾You must set the environment variable ADAMS_CONTROLS_WTIME Generally, this waiting time is enough to initialize connections between AMESim and ADAMS.The AME_AD type path (that can be found in the .inf file generated by ADAMS), for example: D:\PROGRA~1\MSC~1.ADA\To use this interface using amesim_adams_gsec.make located in $AME/interfaces/adams/ should not contain the library dform.lib which is reserved for Fortran compilers.The library for ADAMS must be replaced in the AMESim installatio on the ADAMS version used. The library files are located in $AME/libadams/lib as shown below.Replace AMEADAMS.lib with the correct library file4. Importing AMESim into ADAMS4.1. PreliminaryThe recommended way of working is to first create independent sub-system models in AMESim and ADAMS,each of which has a very simple model of the other domain sub-system.Thus if the end result of a simulation study is to investigate how a hydraulic actuator system will work in a mechanical system it is often best to first model the hydraulic system separately with a simplified model of the mechanical system using the mechanical submodels available in AMESim. This would probably be a prescribed velocity and displacement.In parallel a separate model of the mechanical system would be built in ADAMS with a simplified hydraulic system. This would probably be a prescribed force instead of an actuator. The two sub-system models should then be verified thoroughly. As much independent tuning of the sub-systems as possible should be done at this stage. When the two separate models work properly, they can be integrated.A good general rule is that the ports where the hydraulic and multi-body sub-systems are connected will correspond to hydraulic linear actuator rods or the shafts of hydraulic pumps, motors or rotary actuators.It is not too difficult to think of exceptions but the overwhelming majority of applications will satisfy this rule.You will look at one simple system that uses this way of interfacing. The tutorial case is the ADAMS tutorial example of the antenna. It is strongly recommended that you reproduce this system.When using the interface, there are four important points to treat carefully•units,•sign conventions,•implicit variables (when using AMESim from ADAMS),•numerical aspects.With reasonable care these points can be solved without any problem.The problem of different units in ADAMS and AMESim often leads to the need for the interfacing variables to be adjusted with some unit conversion factor.What we mean by a sign convention is the significance of the signs of forces, displacements and velocities in both AMESim and ADAMS. It is almost always necessary to reverse the sign of displacements and velocities when they are imported into AMESim if hydraulic jacks or hydraulic pumps, motors or rotary actuators are used. Since the sign convention depends on the interfacing of components and variables it is necessary to use caution regarding the sign. This is another good reason for creating two separate sub-system models. The single software simulation results will give good insight into the system behavior and make any sign errors in the combined simulation apparent.As explained in the AMESim manual, AMESim can solve two kinds of systems of differential equations: ordinary differential equations (ODEs) and differential algebraic equations (DAEs). The latter uses implicit variables. The interface between AMESim and the General State Equation in ADAMS supports only ODEs. It is therefore impossible to use any submodel in AMESim that uses implicit variables when exporting the model into ADAMS. It may also be necessary to modify the AMESim model to eliminate any implicit variables that may be created to resolve algebraic loops.When working from ADAMS, numerical problems arise due to the fact that the interface uses the ADAMS integrator, which is tuned to work well with the equations governing multi-body systems. The numerical characteristics of a fluid power system are different. Another source of numerical problems is that an AMESim model when run with the AMESim integrators can employ some special tricks to deal with discontinuities. This is not possible when using the ADAMS integrator. In fact, the documentation of the ADAMS GSE facility, states that the imported system of ODEs must be continuous. It is therefore recommended to avoid hard discontinuities completely in the AMESim model. By a hard discontinuity we mean that there are jump changes in the values of state variables. Fortunately very few AMESim submodels employ hard discontinuities. Avoid the following hydraulic actuator icons that have an integral mass as the corresponding submodels employ hard discontinuities.It is not impossible to use these submodels but if you do, make sure that the jack never hits its end-stops. However, submodels associated with alternative icons employ elastic end-stops, which do not have hard discontinuities. Hence it is preferable to use these.USE THESE ICONSNOT THESESimilarly if you use the mechanical icons, , use MAS21 not MAS005.Looking at the input and output requirements of these preferred submodels and at the requirements of hydraulic pumps and motors, a second general rule becomes apparent. The ADAMS model normally calculates position and velocity, (or angle and angular velocity) and passes them to the AMESim model, which calculates the corresponding force (or torque).Again it is possible to think of exceptions but this rule is very useful.In the same way when working from AMESim, numerical problems can arise when importing a large ADAMS system. The AMESim integrator is not designed to solve such problems, and simulation times may rise significantly.In these cases the co-simulation interface can be a solution if no workaround is found to make the full import facility efficient.4.2. Import AMESim models into ADAMSIn this section you will focus on the interface method to import the AMESim model into ADAMS. We designed the facility for multiple reasons:An ADAMS user needs to integrate a validated AMESim component into a mechanical system; he can still work with ADAMS facilities while taking advantage of AMESim’s ability to design multi-disciplinary control systems.•AMESim may sometimes encounter difficulties in solving a complex ADAMS mechanical structure; in this case, we suggest that user tries the other methodfor coupling the systems, especially if the AMESim system is simple.•This methodology requires no supplementary license for A/controls product.In this case, you will use AMESim subsystem in ADAMS as a general state equation (GSE) block. ADAMS executable will communicate with AMESim using a library. In fact, AMESim will not generate an executable as usual but rather a dynamic link library (dll) on Windows platforms or a library (so) on UNIX platforms.One advantage of this methodology is that you do not need to have AMESim installed on the ADAMS machine; you will just need an AMESim runtime license.4.2.1. Preparing an AMESim model for export to ADAMSIn this section, you will see how to export an AMESim system into ADAMS.In Sketch mode, construct your AMESim system with non-connected ports corresponding to ADAMS inputs and outputs. Then, select Modeling Interface block Create interface icon…, as shown in the screen capture below:Figure 1: Creating export icon in AMESimIt opens a dialog box window named Interface Icon Creation, you select there a Type of interface it should be Adams or AdamsCosim depending whether you want to run discrete coupling or continuous export.Set the number of input variables to ADAMS and output variables from ADAMS and give them a name.In the antenna case it should be one input and two outputs and the created icon looks like this:Figure 2: AMESim subsystem containing ADAMS blockIt is also possible to change the interface status without having to re-do the export, just go to the menu and use Modeling Interface block Display interface status. Then you can switch from Adams to AdamsCosim.Now switch to Submodel mode and Parameter mode. After the compilation of the system AMESim creates the library. Switch to Simulation mode to generate all necessary files or by using File Write auxiliary files.The model cannot have implicit variables otherwise the interface does not work. During the compilation process, the following information is presented:You are now ready to work under ADAMS and import the AMESim system; this is the subject of the next section.4.2.2. Importing the model in ADAMSAs an example, you will use the ADAMS tutorial of the antenna controlled within AMESim. This example comes from A/Controls tutorials; copy the A/View command file antenna.cmd from {ADAMS_DIR}/controls/examples/antenna into a working directory.In ADAMS, do not forget to select the working directory where the AMESim model is located. Use the menu item File Select Directory… By default, the working directory is set to $HOME. This interface also uses libraries located in the $AME/$MACHDIR where $MACHDIR is the machine directory, for example win32 for Windows. This variable must be in the patch directory.¾Import the file within A/view environment.¾The ADAMS model contains an input on the azimuth_motion_csd. variable to force the rotation during the simulation. This input must be deactivated because it is managed in the controller (AMESim model). If we do not deactivate this variable, there will be a conflict between the AMESim control and ADAMS control.To do this, select the Edit Deactivate entry. This action displays the Database Navigator to access the data tree.In the window Database Navigator select azimuth_motion_csd.Figure 3: Deactivate a motion in A/View Apply by clicking OKIf we reopen the Database Navigator, the variable appears as OFF4.2.2.1. Step 1: Create the arrays for inputs, outputs and statesAdams 2005: In A/View go to the Build Controls Toolkit menu.Adams 2008: In A/View go to the Build Data Elements Array menu.¾First, choose the U input array. There you create inputs to the AMESim subsystem, so it will be a 2-dimensional array containing ADAMS variables for velocity and position.Adams 2005Adams 2008¾ Next choose X states array.- discrete export:X state array size = 1 (a dummy state variable)- continuous export: size of the array = AMESim number of states (*) (if = 0 put 1) (*) this number is displayed in the build dialog box.The model cannot have implicit variables otherwise the interface does not work.Adams 2005Adams 2008¾ Finally, choose Y output array. It represents the outputs from AMESim so in our case it will be a 1-dimension array for the control torque.Adams 2005Adams 20084.2.2.2. Step 2: Association of array output value to the modelThe control torque computed by AMESim needs to be associated with the ADAMS model. You do it in the single component torque using ARYVAL ADAMS function. This one permits you to get an array value.Note that, as a first argument to this function you use the array of outputs and the second argument is the position of the required value; 1 in our case.From the Database Navigator, select the azimuth_actuator and we have access to the following dialog box to modify the functionFigure 4: Associate AMESim output to the ADAMS model4.2.2.3. Step 3: Creating the GSE and linking with the AMESim libraryIn the Build System Elements General State Equation menu, choose New… thisopens the dialog box window below.Fill in the window as shown in the following figures. The States line corresponds to the coupling method you chose previously under AMESim; choose discrete for a co-simulation and continuous for an export. The User Function Parameters field always needs three parameters and corresponds respectively to the ID of U Array, Y Array and X Array. AMESim will need them to be able to get correct values from ADAMS during simulation.Figure 5: Creating a GSE in ADAMS; discrete modeFigure 6: Creating a GSE in ADAMS; continuous modeOnce completed, you have to indicate to A/Solver to use the AMESim library.Go to the Settings Solver Executable… menu, in the dialog box window for Solver Library supply the AMESim library path as shown in the figure below:Figure 7: A/Solver settings when using AMESim libraryIn AMESim, select the appropriate settings for the simulation4.2.2.4. Step 4: Running a simulationCreate a command script. Here is an example of a Solver command script:simulate/dynamics, end=0.250000, dtout=0.001 Select Simulate Simulation Script … NewSince A/Solver will use an external library only scripted simulations are available. Select Simulate Scripted Controls …Run the simulation within ADAMS, at the same time the AMESim library writes a result file. The AMESim model is executed in the background. The communication with ADAMS takes place at the library level (dll on Windows and so on Unix platforms). In the aside figure you can notice that AMESim outputs some messages during the simulation.4.2.2.5. Step 5: Checking the resultsIf you have AMESim installed on the same machine, you can look at the results within AMESim. Otherwise, you can focus on ADAMS results only.Results of common variables are as follows under AMESim.In Adams we can also see the variable curves.5. Importing Adams into AMESim5.1. IntroductionAs an example, you will use the same ADAMS tutorial of the antenna controlled within AMESim.The final sketch in AMESim will look like:Figure 8: Antenna sketch in AMESim¾The example comes from A/Controls tutorials; copy the A/View command file antenna.cmd from {ADAMS_DIR}/controls/examples/antenna into a working directory.In ADAMS, do not forget to select the working directory where the AMESim model is located. Use the menu item File Select Directory… By default, the working directory is set to $HOME¾Import the file within the A/view environment.¾The ADAMS model contains an input on azimuth_motion_csd variable to force the rotation during the simulation. This input must be deactivated because it is managed in the controller (AMESim model). If we do not deactivate this variable, there will be a conflict between AMESim control and ADAMS control.To do this, select the Edit Deactivate entry. This action displays the Database Navigator to access to data tree.In the window Database Navigator select azimuth_motion_csd.Figure 9: Deactivate a motion in A/ViewApply by clicking OK.If we reopen the Database Navigator, the variable appears as OFF5.2. Preparing an ADAMS model for export to AMESimIn this case, AMESim is the master software, you will launch simulations from AMESim and AMESim controls ADAMS simulation.There are two ways to export ADAMS into AMESim:•Discrete export, or co-simulation mode, AMESim tells ADAMS to supply its outputs at fixed intervals, ADAMS solves its system,•Continuous mode, AMESim gets the complete system from ADAMS and tries to integrate all equations, ADAMS acts then as a function evaluator.These modes require that you have a valid license for A/Controls.The ADAMS side of the procedure is unchanged whichever mode you use. It is only in AMESim that you make your choice.5.2.1. Step 1: Check exchanged variablesIn this step, you will check the definition of some ADAMS state variables1. You will use them as exchanged variables between the two software packages, for example for a hydraulic actuator modeled in AMESim and acting on an ADAMS mechanical structure, these variables should be a force, a position and a velocity. AMESim needs position and velocity and computes a force.Outputs from ADAMS, often velocity and position, are defined with ADAMS intrinsic functions; AZ( ) for an angle measurement, WZ( ) for a rotational velocity, DM( ) for a displacement magnitude.1 Be careful, the meaning of state variables is not the same in AMESim and in MSC.ADAMS. For the latter these are simple variables defined by an algebraic equation whereas in AMESim these are the variables integrated by the solver.Select the variables in the Database NavigatorBe careful with units (accessible from Settings/Units… menu in A/View). They should be compatible with what AMESim expects, if you do not want to change them in ADAMS, do not forget to place a gain (conversion factor) on the AMESim sketch before inputting the signals into AMESim submodels.Inputs to ADAMS, mainly forces/torques, are used in standard elements like single component force/torque or general force (6 components). At creation, these variables are set to zero value because the other software (AMESim) will compute their values.In our example, the unique input variable is referenced in a torque single component using the function VARVAL.The element azimuth_actuator can be accessed from the Tools Database Navigator…menu in A/View. The control_torque state variable is accessible from Build System Elements State Variables Modify… menu.Figure 11: Creating input variable in ADAMSOnce you have created input and output variables, in the next section you will learn how to define the interface in ADAMS.。

adams、amesim联仿遇到的问题

版本：win7 32位下adams13.0，amesimR10 ，以amesim为主仿软件。

adams模型有4个自由度，需要4个输入，遇到的问题如下：
（1）Adams单输入下，加入一个液压缸位置输出变量，然后再通过v/x反馈回AMSEim 的液压缸活塞杆上，系统图如图1，错误提示如图2，此问题有人说是参数设置问题，但是一直调参数也没成功，不知道是系统图搭的不对还是参数设置没调好。

图1 adams单输入系统图图2 AMESim错误提示
将系统图改为图3后，adams单输入下可以仿真。

但是系统图中标记处应该是错的。

图3 adams单输入系统图（修改后）
（2）如果Adams到AMESim的输入不止一个，就会出现问题，AMESim错误提示：Problems with A/Controls：‘AEI_Initialize：1 error in startup’AMESim model did an
abnormal exit！Adams则是直接vcontrols.exe崩溃。

系统图如图4，错误提示如图5
图4 联防两输入系统图
图5 adams与amesim错误提示
总结遇到的主要问题：
（1）参数设置，不知道如何正确设置各元件参数。

（2）系统图的搭建，系统图都是简单搭建的，有些不合理的不知道如何
修改。

ADAMS+AMESIM+SIMULINK操作说明

ADAMS+AMESIM+SIMULINK总体思路：对于一个实际的机械电液控制系统的建模仿真，用ADAMS进行机械部分的建模，AMESIM进行液压部分的建模，SIMULINK进行控制部分的建模。

将ADAMS建立的机械模型导入到AMESIM中（通常接口处是油缸或是马达），再将整合后AMESIM模块当作一个整体的模块导入到SIMULINK中，在SIMULINK中进行仿真。

仿真时，SIMULINK给出控制信号以控制AMESIM输出的力或是扭矩，AMESIM给出力或是扭矩来控制ADAMS机械系统的运动量（位移、速度、加速度。

），ADAMS会将运动量反馈给AMESIM，SIMULINK 可根据这些反馈做出相应的控制。

下面以一个例子来简介三者联仿的步骤：例子：一只油缸固连一只仅受重力的小球，小球的初始状态为静止。

现在仿真这么一个状态：油缸从一端运动到另一端时的小球的运动变化。

步骤一：准备工作。

1.首先得装好四个软件。

我用的是ADAMS2005，AMESIM8.0，MATLAB2007b，Microsoft Visual C++ 6.0。

另外三个软件要有相应的破解文件以支持联仿。

2.ADAMS到AMESIM的设置：在Windows中设置环境变量%AME_ADAMS_HOME%，该环境变量的值为ADAMS的安装路径（例如C :\ADAMS2005。

注意在ADAMS的安装路径中不能出现空格）。

3．AMESIM到SIMULINK的设置：（1）确认在系统变量PATH中包含系统安装目C：\WINNT＼System32。

（2）在Matlab的目录列表里加上AMESim与Matlab接口文件所在的目录％AME％＼MATLAB＼AMESim。

File→Set Path→Add Folder加上c:\AMESim\MATLAB\AMESim。

（3）确认是否在AMESim中选择VC作为编译器。

具体操作在AMEsim→0pions→AMEsim→Preferences→Compilation/Parameters中。

联合仿真

一、AMEsim和ADAMS的版本要匹配，如AMEsim8.0/ADAMS2007匹配,版本不匹配可造成联仿出现问题，如AMEsim10.0/ADAMS2007，版本不匹配，运行时会出现Requesting ame_adams runningtime license……问题。

二、安装Microsoft Visual C++编译器。

三、设置环境变量。

1.我的电脑——属性——高级——环境变量——新建（用户变量和系统变量均可），变量名：AME_ADAMS_HOME;值：ADAMS的安装路径（C:\MSC.Software）。

2.测试变量。

运行——cmd——echo % AME_ADAMS_HOME %——回车，当出现其安装路径则证明设置正确，如若没有，重启试试，echo和% AME_ADAMS_HOME %之间有空格。

四、ADAMS建模1.建模2.定义状态变量（build——system element）3.定义输入输出变量，即定义哪些变量是输出，哪些是输入。

4.定义跟随输入变量而变化的输出函数，定义赋予输出变量的的输出函数。

五、AMEsim建模1.建模2.导入libadams库（modeling）3.设置c++环境，（Tools——option——AMEsim Preference——Complication/Parameters）4.导入adams模块（modeling——Interface block——import adams model）5.设置参数仿真（AMEsim（0.001）的仿真间隔要比adams（0.01）的小）六、后处理1.AMEsim 按常规画图2.ADAMS在ADAMS 中，用户可以将仿真结果加载到模型中。

打开ADAMS 的File菜单，选择Import后选择ADAMS/Solver Analysis（req, gra, res），选择在联合仿真时创建的三个文件中的一个并将输入相关联的模型名字，然后用户可以在ADAMS中进行动画演示以及通过A/Postprocessor来绘制相关变量的曲线。
