摘　　要：利用ANSYS软件,以平板试件为对比基准,对具有仿生非光滑通孔结构试件的耐磨机制进行了有限元分析。分析表明,仿生非光滑通孔具有削弱应力集中、均匀分布应力的功能,使试件整体受力均匀、接触状态良好,从而提高试件的摩擦磨损性能;通孔附近前大后小的应力分布方式,有利于收集润滑油、切削磨粒,改善其润滑状态,减小磨粒磨损。Applying the software of ANSYS,based on the flat plat specimen, the finite element analysis about the wear resistance of bionic non-smooth through-hole specimen was given. Analysis result shows that the functions of cutting stress concentration and rectangular distribution stress of bionic non-smooth through-hole make the stress of the specimen uniformity and have a good contacting condition, which could promote the property of the frictional wear ; the large forward and small backward stress distribution mode near the through-hole makes the through-holes have the functions of collecting lubricating oil and cutting abrasive grain, improving lubricate state, decreasing the wear of abrasive grain.
