摘要
为了研究轿车电磁与摩擦制动集成系统的制动性能,将混杂理论应用到制动集成系统的建模和仿真研究中,通过分析电磁与摩擦制动集成系统的相互影响、协调作用的混杂特性,建立了电磁与摩擦集成制动系统模式切换控制模型和整车七自由度动力学模型,并在此基础上,采用MATLAB/SIMULINK对轿车电磁与摩擦制动集成系统的3种不同制动工况进行仿真分析。研究结果表明:电磁与摩擦集成制动模型可以对集成制动系统性能进行仿真分析;在满足制动强度的前提条件下,集成制动系统可以按照切换控制策略协调稳定地达到制动效果;在制动强度要求不高的情况下,电磁制动可以满足部分制动力的需求,从而改善了摩擦制动状况。
In order to study the braking performance of the integrated electromagnetic and frictional brake system of car,the theory of hybrid system was applied in the modeling and simulation of this system.A switch control model among different modes and a car dynamic model of 7DOF were established by analyzing the hybrid characteristics of mutual influence and coordination function in the integrated braking system of electromagnetism and friction.And on this basis,simulation analysis of three different braking modes was carried out by MATLAB/SIMULINK.The results show that the established simulation model of integrated electromagnetic and frictional brake system can make the simulation analysis of the integrated brake system.On the premise of satisfying the braking intensity,the integrated braking system can achieve the desired braking effect harmoniously and steadily according to the switching control strategy.When the requirement of braking intensity is not high,the electromagnetic brake can satisfy part of the requirement of braking force,which can improve the frictional brake condition.
