摘　　要：研究了涂层对凸轮接触应力分布的影响。通过有限元仿真的方法,为涂层赋予不同弹性模量的属性,对凸轮的应力分布进行分析。结果表明,涂层能有效的减小凸轮基体表面的应力,但涂层过大的弹性模量会使导致涂层与基体的材料失配。The stress distribution of timing valve cam with coating is researched in this paper. Finite element Method is used to simulate the contact stress of cam with different types of coating. As a result, coating can prohibit the stress of cam effectively. But coating with high elastic module will lead to a damage to the part.
