利用反力式制动试验台对前、后轮的加载能力进行了分析，并得出如下结论：（1）因存在系统的微观自激振动，致使滚筒对车轮的加载能力在一定范围内不停地波动；（2）加载能力一般不低于轴荷的60％，对于后轮行车制动力的检验，试验台加载能力的下限值可能低于60％；（3）为使后轮驻车制动力检验的加载能力不低于整车重力的20％，试验台应设置限制车辆后移的辅助设施，以提高驻车制动力的加载能力。
The load capacity of the front and rear wheels is analyzed by the reaction force brake test stand, and the following conclusions are drawn: (1) Due to the microscopic self-excited vibration of the system, the loading capacity of the drum to the wheels is not within a certain range (2) The loading capacity is generally not less than 60% of the axle load, and the lower limit of the loading capacity of the test rig may be lower than 60% for the test of the rear wheel drive braking force; (3) Vehicle braking test load capacity of not less than 20% of the vehicle gravity, the test bench should be set to limit the vehicle after the shift of auxiliary facilities to improve the parking brake force loading capacity.
