凹坑形非光滑表面的耐磨性分析及优化设计
Wear Resistance Analysis and Optimization Design of Pit-Shaped Non-smooth Surface
摘要
Abstract
The surface‐surface friction pair parts in engineering application were simulated by two rectangular blocks .The small block was built with square pit ,the big block was built with smooth surface .The parameterized analysis model of the blocks was built by ANSYS and APDL language .With the method of single factor experiment ,the effect of pit side length ,pit depth and pit spacing on the wear resistance was researched in the finite element simulation .The results in‐dicate that pit surface can even load and improve the surface wear resistance by producing more compressive strain energy and more bending strain energy in the process of contact .With the in‐crement of pit side length and pit spacing ,the wear resistance of pits surface increases at first , then decreases .With the increment of pit depth ,it increases gradually .Finally ,by the optimiza‐tion design of non‐smooth surface morphology ,the wear resistance of pit surface becomes optimal w hen the side length is 20 μm ,the depth is 80 μm ,the spacing is 90μm .关键词
