自卸车是一种通过车自身的倾卸机构,能够将车斗中货物倾卸出去的一种车。自卸车倾卸机构的创新设计就是对现有的自卸机构进行创新再设计,使其满足自卸的使用要求。平稳倾卸货物。如下图中,液压缸作为动力原件,液压缸的伸缩,通过六杆机构的转换,使车斗倾斜,达到倾卸货物的目的。

Abstract
Our group choosesdump truck dumping mechanism innovation design as curriculum design questions. In order to complete the course design, we first look for the dump truck dumping mechanism about the history of the dump truck, understand the development course and present situation. Then we find about dumping domestic and foreign patents, and analyzes the mechanism, draw the mechanism diagram. Know the dump truck, there are all kinds of different organizations, and to understand the present commonly used self-discharging institutions and self-discharging mechanism the future trend of development.

(1)选小车型设计,车斗长5米左右.
(2)为使货物倾卸完全,车斗最大倾角应在45~70度,可以选择60度.
(3)单级液压缸,最大伸缩长度在0.5~0.8m.
(4)机构纵深约为0.5m.

最早的自卸车是以马拉的形式的二轮装卸车,货物重心在二轮车的轮轴上,当装载货物时,只需要放到轴上就可以了,货物前方用绳子勾住固定;卸载时倾卸车即可。这种二轮车曾用在开放矿场,用马匹拉着在铁轨上行走。
In order to creative design, our site to the common dumper's self-discharging mechanism photos. Body analysis and the kinematic chain of generalization, several comprehensive, specialization and shape and a series of process that.Atlast, we give27 possible mechanism diagrams. In comparison, we chose a not current popular type of mechanism diagram as their innovative design. According to the requirements of the more common to dump truck, car bucket maximum Angle of inclination, the agency depth, hydraulic cylinder expansion distance, reasonable structure and so on, we design the innovation organization in the size of the inventor.

摘要
我们组选择自卸车倾卸机构的创新设计作为课程设计的题目.为了完成课程设计,我们首先查找了关于自卸车倾卸机构的发展史,了解了自卸车的发展历程与现状.然后我们查找了关于自卸的国内外专利,并分析其机构,画出机构简图.知道了自卸车有各种不同的机构,并了解了现在常用的自卸机构以及自卸机构未来的发展趋势.
为了创新设计,我们现场对常见自卸车的自卸机构拍照.分析机构,并进行了运动链的一般化,数综合,特定化和具体化等一系列过程.最后得出27个可能的机构简图.在进行比较时,我们选择了一个不是当前流行类型的机构简图作为自己的创新设计.按对自卸车较为常见的要求:车斗最大倾角,机构纵深,液压缸伸缩距离,结构合理等,我们设计了创新机构的尺寸.在用inventor对其进行运动仿真后,发现结构运动平稳.然后我们又用matlab对机构进行建模,仿真.得出机构的角速度,角加速度等图形.发现机构角速度变化幅度不大,符合仿真动画,满足实际要求,因此,我们确定了我们的创新设计符合要求并将其作为最终的课程设计的方案.
