摘　　要：基于伪刚体模型,以机构疲劳强度为优化目标函数,考虑各个随机变量的影响和各种约束条件的概率形式,建立了一种柔性曲柄滑块机构的优化设计模型。算例表明,该模型正确可靠,计算结果显示机构的结构尺寸和材料特性对疲劳强度影响较大。Based on the pseudo-rigid-body modal, taking the fatigue strength of mechanism as the objective function of optimization and considering the effects of each random variable and various probability forms of constraint conditions, a kind of optimization designing model of the flexible crank slider mechanism was established. A calculational example showed that this model was correct and reliable, and the result of computation demonstrated that the structural dimensions of mechanism and the material＇ s characteristics bear rather big influence on the fatigue strength of the mechanism.
