表面处理对柔轮材料力学性能影响的有限元分析
Finite element analysis on influence of surface treatments on mechanics of flexible gear material
摘要
Abstract
The influence of different surface treatment processes on the mechanics of 15-5ph stainless steel, which is commonly used for flexible gear, was studied. Firstly, a 15-5ph stainless steel specimen was tested by a nano-indentation tester. The obtained load?displacement curve was compared with that simulated by finite element method, verifying the effectiveness of the indentation model established by the finite element method. Based on the above results, the influence of different surface treatments on the flexible gear material was modeled and analyzed. The results show that increasing coating's elastic modulus can increase the equivalent hardness and stiffness of coating-matrix system; and that increasing carburizing layer thickness appropriately reduces the stress of flexible gear matrix without affecting engage precision. If the residual compressive stress caused by shot peening becomes larger, the equivalent hardness of the matrix material gets larger, and in the meanwhile, the equivalent stiffness will be improved to some extent.关键词
