自支撑变频牵引绞车的结构设计与分析

应用SolidWorks、ANSYS、ADAMS等CAE辅助设计软件,对一种自支撑变频牵引绞车进行了设计,在有限空间内进行了总体排布和结构设计,并对其中主要结构件及参数进行了介绍。对自支撑固定装置进行了动力与运动学仿真,并对其四连杆参数进行了优化。根据运动学仿真得出的铰接点受力参数,并结合极端工况下的受力分析,应用ANSYS对结构件进行了应力分析,根据应力分析结果对结构进行了优化设计。从样机使用情况看,所设计的结构件结构合理、可靠,满足使用要求。

CAD/CAE system for the ring planetary reducer with small tooth number difference

A CAD/CAE system of the ring-type planetary reducer with small tooth number difference is presented. It is a parameterized CAD/CAE system adopting the object-oriented technique and comprising in itself the geometric feature database (including the modules of ring-plates with inner teeth, eccentric shaft modules and output shaft modules), standard component database and material database. In comparison with design by handwork , this computer aided design and analysis system has the advantages of improved quality, shortened design period and reduced cost. The reliability of the system has been verified by a illustrative example.
