螺栓连接疲劳失效机理及其预防措施

Bolt Fatigue Failure Properties and Prevention Methods

螺栓疲劳失效是汽车设计开发中经常遇到的问题之一。介绍螺栓疲劳失效的特征及螺栓疲劳失效的影响因素,并通过案例分析,提出在汽车设计中通过设计优化预防螺栓疲劳失效发生的措施。

Bolt fatigue failure is a problem often happened during our vehicle development. The bolt fatigue failure; s properties and effect factors are introduced, and how to optimize the design to avoid fatigue failure is also discussed by some case analysis.
