Rolling rear pivotal and rotary suspension equipment finite element analysis and optimum structural design

运用ANSYS软件,对某型滚柱式后枢轴回转悬挂装置在高载荷作用下的主接头组件进行了有限元计算和分析。通过对摩擦力学微观模型的分析,构建了滚珠的受力方程,并基于此提出了几类结构优化设计方案,从而解决了高载荷作用下该型机构卡死问题,为后枢轴回转投放悬挂装置在高承载能力上的设计优化提供了较强的工程应用及参考依据。

Utilizing ANSYS software,this thesis makes finite element calculation and analysis to main connector assembly of certain type rolling rear pivotal and rotary suspension under the actions of large load. By analysing friction force microphysics model,form the pressed equation of ball bearing, therefrom produce several kinds of optimum structural design programs ,thus settle the block problem of this type device under the actions of large load,and provide the potent engineer application and reference basis for optimum design of rear pivotal and rotary release suspension in high carrying capacity.
