发动机凸轮轴断裂失效分析和预防

Engine Camshaft Fracture Failure Analysis and Prevention

凸轮轴是活塞式发动机配气机构的重要组成部件,在发动机领域有着广泛的应用,如果凸轮轴出现断裂失效将会对发动机的正常功能造成致命性的影响,本文通过运用各种失效分析的方法对凸轮轴的断裂失效进行合理分析,并给出相关建议以便改进质量,预防类似的失效模式。

The camshaft is an important component of valve-train piston engine,has been widely used in the field of the engine,if the camshaft appear fracture failure will be fatal influence on the normal function of the engine,this paper use many kinds of failure analysis method to analysis the reason of fracture failure of the camshaft,and gives Suggestions to improve quality,to prevent the similar failure mode.
