SolidWorks是一款功能强大的三维设计软件，具有强大的参数化建模功能。在SolidWorks的标准菜单中包含了各种用于创建零件特征和基准特征的命令。通过运用这些特征造型技术可以很方便的设计出需要的实体特征。应用SolidWorks软件，可以建立出齿轮泵各个零部件的三维模型，进行装配后建立齿轮泵虚拟样机。

参数化造型设计是SolidWorks软件核心功能之一，包括曲面和实体造型以及基于特征的造型等。它提供尺寸驱动的几何变量，用交互式方法检查模型变化的结果，其模型可智能化。参数化造型虚拟技术通过记录几何体间的所有依存关系，自动捕捉设计者的意图。

此设计中主要利用三维设计软件SolidWorks，建立了齿轮泵的虚拟样机模型，并在此基础上利用SolidWorks软件对齿轮泵进行运动仿真、基体受力分析等。建立运动机构模型，进行机构的干涉分析，跟踪零件的运动轨迹，速度、加速度、作用力、反作用力和力矩等，并用动画、图形、表格等多种形式输出结果，其分析结果可指导修改零件的结构设计或调整零件的材料。设计的更改可以反映到装配模型中，再重新进行分析，一旦确定优化方案，设计更改就可以直接反映到装配模型中。此外还可以将零部件在复杂运动情况下的复杂载荷情况直接输出到主流有限元分析软件中以作出正确的强度和结构分析。

ABSTRACT

Three dimensional design software SolidWorks is a powerful, powerful parametric modeling capabilities. SolidWorks standard menu includes the commands for creating part features and Datum features. Through the application of the feature modeling technology can easily design needs solid features. Using SolidWorks software, you can build three dimensional models of the various parts of a gear pump, Assembly established gear pumps after the virtual prototype.

Design of parametric modeling is one of the core features of SolidWorks software, including surface and solid modeling, and feature-based modeling. It provides variable geometry of dimension-driven, interactive method checks the results of model changes, its model can be intelligent. Parametric modeling technology of virtual record all dependencies between geometry, automatically capture the designer's intent.

Mainly use three dimensional design software SolidWorks in this design, the establishment of a virtual prototype model of a gear pump, and on this basis using SolidWorks motion simulation software to gear pump, mechanical analysis of substrate. Establishing a mechanism model, interference by institutional analysis, track the movement of parts, speed, acceleration, force, reaction forces and moments, with animation, graphics, tables, and other forms of output, its analysis results to guide modification adjustment of structure design of the part or parts of the materials. Design changes can be reflected in the Assembly model, then re-analysis, once the optimization plan, design changes can be reflected directly in the Assembly model. Can also be components in complex motion under complex load conditions direct output to the mainstream in the finite element analysis software to make the right intensity and structure analysis.
