变形板式橡胶支座疲劳寿命估算

On fatigue lifespan estimation of rubber bearings of deformed plates

针对橡胶的特性,建立橡胶支座的疲劳损坏模型,通过对应变幅度的求解,估算支座的疲劳寿命,结合具体实例,对产生纵向变形的圆形板式橡胶支座进行疲劳寿命的估算,得出了一些有益的结论。

Aiming at the feature of the rubber, the paper establishes the fatigue damage model of the rubber bearings, according to the solution to the strain amplitude and the estimation of the fatigue life of the bearings, estimates the fatigue life of the round plate rubber bearing which form the longitudinal deformation by combining with factual examples, and concludes the beneficial results.
