一种汽车综合制动性能检测系统的设计与研究

Design and research of automobile comprehensive braking performance test system

设计的汽车综合制动性能检测系统以现有的反力式滚筒试验台为基础,增加了制动踏板力、制动管路压力等测量装置,设计软件系统进行多通道数据测量、采集与处理,测量模拟车辆行驶时的实际地面制动力。该系统可以对测试车辆制动踏板采用手摇加载方式对制动管路进行加压,在制动器反应、制动力上升、持续制动和放松制动等制动过程中,实时、同步测量测试车辆的制动踏板力、制动管路压力和车轮制动力变化情况,进而将研究成果应用于由于交通事故导致制动管路损坏而4个车轮及其制动器均完好的这一类事故车辆制动性能鉴定工作中。

The automobile comprehensive braking performance test system based on the existing anti-force rolling brake testing platform,increased the measuring device of brake pedal force,brake pipe pressure,the designed software system had the ability of multi-channel data measuring,collecting and processing,measuring the actual ground brake force when simulate the moving vehicle.The system can boost the pressure of brake pipe by hand loading mode to the test vehicle brake pedal,synchronous measure the test vehicle brake pedal force,brake pipe pressure and the variation of the wheel brake force,when brake respond,brake force rise,continuously brake and brake relax,and then apply research achievement to accident vehicle braking performance forensic work that the brake pipe damaged but four wheels and brakes were in good condition.
