| 摘 要： | 研究的目的是建立一种运动机构强度可靠性优化设计方法.在用基本杆组法进行机构运动分析和动力分析的基础上,分别以构件材料强度、密度、截面尺寸为随机变量,机构质量为目标函数,可靠性指标为约束函数,构件截面尺寸为设计变量,将传统优化设计与可靠性分析相结合,建立基于基本杆组法运动机构强度可靠性优化设计的均值模型.以曲柄滑块机构为例,用一次二阶矩法进行实例仿真,得到设计变量的最优解.

| Abstract: | The aim of the research is to establish the optimization theory and method of strength-reliability about operating mechanism.In the first,mechanism was analyzed at kinematics by using Assur-group.Secondly,reliability was combined with optimization.Random variables included material strength,density and component section sizes.At the same time,mechanism mass was taken as objective function,reliability as restraint function and component section sizes as design variable.Finally,the mean model of operating mec... |
