硅油风扇离合器非故障性失效模式分析

Failure mode analysis of viscous fan clutch

本文分析了硅油风扇离合器在汽车行驶工况中的工作原理,得出由于多方面因素导致硅油风扇离合器原设定的温度类比关系与实际的温度类比关系不符是非故障性失效的根本原因,并且提出了非故障性失效模式的解决措施和思路。结果表明,解决措施的效果明显。

This paper analyzes the working principle of viscous fan clutch in the condition of the car,draws non-faulty of viscous fan clutch is the root cause of the failure mode,and puts forward solutions and ideas of non-fault failure mode.The results show that the solution effect is obvious.
