摘　　要：通过分析单自由度蹄式制动器制动时的受力情况,考虑制动鼓和摩擦片之间的接触,利用ANSYS/Workbench软件创建二者之间的摩擦接触关系,通过模拟制动器的制动过程测试摩擦片的接触压力,并将得到的压力分布规律与理论规律进行对比分析,进而优化制动器的摩擦片起始角,获得更好的制动性能。Through analyzing a shoe-type brake of SDOF under load when applied, and in consideration of friction slide between the drum and the friction disc, we utilized ANSYS/Workbench soft ware to set up relationship of friction contact there-between. Besides, we tested contact pressure at the friction disc by simulating application process of the brake for the purpose of comparison and analysis between of the pressure distribution law so obtained with the theoretical law. And then, we went further to optimize initial angle of the friction disc in the brake, thus getting better brake functions.
