摘要

某汽车稳定杆连接杆球头销发生断裂现象,采用宏观观察、化学成分分析、扫描电镜分析、金相检验、硬度测试等方法分析了其断裂原因,用有限元分析方法进一步分析。结果表明:未对球头销进行调质热处理,导致其力学性能降低,球头销在外界交变载荷的作用下发生了断裂。

Abstract

The ball head pin of the connecting rod of an automobile stabilizer bar fractured. The fracture causes were analyzed by means of macroscopic observation, chemical composition analysis, scanning electron microscope analysis, metallographic examination and hardness test, and further analyzed by finite element analysis. The results show that the mechanical properties of the ball head pin were reduced without quenching and tempering heat treatment, and the ball head pin was broken under the action of external alternating load.
