机械原理课程设计

1、机械原理课程设计1机械原理课程设计说明书自卸车倾卸机构创新设计学院:机械工程学院班级:组员:指导教师 :二一三年一月四日摘 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,并了解了现在常见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

2、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.abstractour group chooses dump truck dumping mechanism innovation

3、design as curriculum design questions. in order to complete the course design, we first lookfor the dump truck dumping mechanism about the history of the dump truck, understand the development course and present situation. then we find aboutdumping domestic and foreign patents, and analyzes the mech

4、anism, draw the mechanism diagram. know the dump truck, there are all kinds of differentorganizations, and to understand the present commonly used self-discharging institutions and self-discharging mechanism the future trend of development.in order to creative design, our site to the common dumpers

5、self-dischargingmechanism photos. body analysis and the kinematic chain of generalization, several comprehensive, specialization and shape and a series of process that. at last, we give 27 possible mechanism diagrams. in comparison, we chose a not current popular type of mechanism diagram as their i

6、nnovative design. accordingto 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 sizeof the inventor. the motion simulation,

7、found that the smooth movement structure. then we use matlab to mechanism modeling, simulation. draw mechanismof angular velocity, angular acceleration and angular velocity change graphics. find institutions range is not too much, in line with the simulation animation, meet资料内容仅供参考，如有不当或者侵权，请联系本人改正或
