可调附着力汽车制动试验台研发

The development of the ABS experimental platform with adjustable adhesion

研制开发了硬件在环ABS试验台,其轮速与车速等数据信号都是由传感器真实测量所得,避免了模拟信号所产生的误差,也减小了简化数学模型时因忽略因素所产生的不可避免的误差。提出了制动时通过对汽车载荷的调整使附着力发生改变的方案,解决了ABS试验台无法精确改变模拟汽车附着力进行试验的难题。最后通过对ABS试验台的试验,得到了较为理想的制动轮速、车速与车轮滑移率的曲线,并测得制动时间与制动距离,为ABS试验台功能的继续完善奠定了基础。

It introduces a new ABS experimental platform.Using the sensors to measure the signal of the wheel velocity and the car velocity from the real vehicle, the platform avoids the unavoidable errors generated from sim-ulation or dynamics models.It proposes the changing adhesion project according to changing vehicle load.To continuously simulate the diverse qualities of the vehicle, the project fits the inertial wheels and a continuously adjusting single inertial.Finally, the platform provides the perfect wheel velocity curves, the vehicle velocity curve and the slip rate curve, and shows the measured brake time and brake distance.This achievement establi-shes the foundation for the ceaseless completing functions of the ABS experimental platform.
