摘要

以某型橡胶球铰为研究对象,提出了一种结合开裂能理论和优化理论的橡胶元件的疲劳优化方法。该方法使用开裂能预测橡胶结构的疲劳寿命,利用应力作为结构优化参量,以疲劳寿命结果指导橡胶结构优化,实现了橡胶弹性元件结构的理论优化和疲劳寿命预测,并为缩短橡胶弹性元件的结构开发周期提供了工程指导意义。

Abstract

This paper introduces an analysis method,which combines the crack fatigue prediction theory and rubber elastic structure optimization,to optimize the structure of a rubber bushing. Using stress in rubber as the optimization parameters,the method can predict fatigue life of the rubber bushing by applying crack energy density. In summary,using the fatigue result,this new analysis method can predict rubber fatigue life and provide optimized structure of rubber parts. This combination of the crack fatigue prediction theory and rubber elastic structure optimization ensures the convenience of engineering application and provides a guidance to reduce rubber structure developing time.
