【摘要】 刹车片是制动系统中最关键的安全零件之一，在保障驾驶员行车安全中起着至关重要的作用，不同的制动工况对刹车片磨损量有不同的影响。为了探究制动工况对盘式刹车片磨损量的影响，利用Ansys Workbench仿真软件，基于Archard磨损模型建立刹车片的磨损仿真模型，并通过APDL命令流添加Archard磨损命令，实现对刹车片的磨损仿真，分析了计算刹车片的磨损量。搭建刹车片摩擦磨损试验台，并随机选取5组不同的制动工况进行刹车片磨损试验，对比分析试验结果与仿真结果，验证了仿真模型的正确性。研究结果表明，在设定的参数范围内，制动压力对刹车片磨损量的影响比制动初速度的影响小；在没有外界热源的干预下，刹车片表面温度对磨损量的单独影响比制动初速度、制动压力等其他参数对刹车片磨损量的综合影响更小。更多还原

【Abstract】 The brake pad is one of the most critical safety part in the braking system, and it plays a vital role in ensuring drivers safety. In order to investigate the effect of braking conditions on the wear loss of disc brake pads, using Ansys Workbench simulation software, the wear simulation model was built based on the Archard wear model; Archard wear commands were added through the APDL command flow to realize the wear simulation of the brake pad, so as to analyze and calculate the wear loss of the brake pad. The brake pad friction and wear test bench was built and five groups of different braking conditions were randomly selected for brake pad wear test, and the test results were compared and analyzed with the simulation results to verify the correctness of the simulation model. The results show that within the set parameter range, the effect of the brake pressure on the wear loss of brake pad is smaller compared to the effect of the initial brake speed; without the intervention of the external heat source, the individual effect of the brake pad surface temperature on the wear loss is smaller compared to the combined effect of other parameters such as initial brake speed and brake pressure on the wear loss of the brake pad.更多还原
