摘　　要：从制动器制动全过程的动态仿真角度出发,重点考察了鼓式制动器摩擦系数、凸轮偏置角和摩擦片包角对制动器制动效能的影响。正交仿真试验分析表明:上述三个因素对制动器效能因数的影响按大小次序是摩擦系数、凸轮偏置角和摩擦片包角。制动器的效能因数随三个因素取值的增加而增大,同时,制动效能因数对摩擦系数的敏感性显著增大,而对凸轮偏置角及摩擦片包角的敏感性却在降低。这将为以后的制动器优化奠定基础。From the friction coefficient, cam Some conclusion can be whole brake process of dynamic simulation point of view of cam brake, on the influence of angle and friction-bias angle on the braking performance of cam brake is mainly focused. gained through the three factors orthogonal simulation analysis： the impact of the three factors on the brake performance is in order of the friction coefficient, cam angle and friction-bias angle. Along with the increase in value of the three factors, the brake factor also increased at the same time. The brake sensitivity about friction coefficient significantly increased, while the brake sensitivity about the cam angle and friction-bias angle reduced. This will be the base for the brake optimization.
