汽车制动试验台驱动电流控制数学模型的建立

The Making of Mathematical Model of Current Control Driven by the Brake Testing

本文研究在试验台上模拟路试车辆的制动问题。通过对客观测量的分析,用驱动电流实现对电补偿惯量的控制,以达到最接近的路试模拟效果。而这一方法的实质正是能量守恒,即电流产生的电能来等效的弥补试验台与路试之间的动能差。以此为理论基础,实时地对驱动电流进行调整,从而得到尽可能逼真的模拟路试的情况,进而对汽车制动性能有一个准确的分析。

The article studies the problem that simulates the vehicles＇ brake in the platform.Through the analysis of the objective surveys,we can use the drive current to realize the control and achieve the best simulation effect.And the substance of the method is just the conservation of energy.In other words,use the electric energy which was made by the current to make up the difference of the kinetic energy caused by the platform.Taking this as the rationale,make the adjustment to the drive current instantaneously.So we can get the best simulation effect,and then we can have an accurate analysis to the brake performance of the car.
