摘　　要：利用Solidworks软件建立液压制动钳活塞和钳体的3D模型,在ANSYS Workbench软件中对液压制动钳耐压性能进行有限元分析仿真。在12MPa均匀正常工作载荷仿真中,钳体最大应力为238.56MPa,最大应变0.05mm;活塞最大应力为164.71MPa,最大应变量为0.04mm。在35MPa均匀过载载荷仿真中,钳体最大应力为543.94MPa,最大应变量为0.15mm。活塞最大应力为481.04MPa,最大应变量为0.13mm。试验结果表明,正常载荷下制动钳处于材料允许载荷下不会损坏,过载载荷下制动钳在薄弱区会出现损坏。In this paper,we use Solidworks software to establish the 3D models of hydraulic caliper piston and caliper body,and perform finite element analysis simulation of hydraulic caliper pressure resistance by ANSYS Workbench software.In the simulation of 12MPa uniform normal working load,the maximum stress of the caliper body is 238.56MPa and the maximum strain is 0.05mm;the maximum stress of the piston is 164.71MPa and the maximum strain is 0.04mm.In the simulation of 35MPa uniform overload load,the maximum stress of the caliper body is 543.94MPa and the maximum strain is 0.15mm;the maximum stress of the piston is 481.04MPa and the maximum strain is 0.13mm.The experimental results show that the brake caliper under normal load will not be damaged under the material allowable load,and the brake caliper will be damaged in the weak area under overload load.
