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 system of car electromagnetics and frictional brakes, the hybrid theory is applied to the modeling and simulation of the integrated brake system. By analyzing the interaction between electromagnetic and frictional integrated systems, , Established the mode switch control model of electromagnetic and friction integrated brake system and the seven-degree-of-freedom dynamics model of the vehicle, and on this basis, using MATLAB / SIMULINK three different brake system of integrated electromagnetic and friction brake system Conditions for simulation analysis. The results show that the integrated braking system can simulate the performance of the integrated braking system. Under the prerequisite of meeting the braking strength, the integrated braking system can achieve the braking effect in a coordinated and stable manner according to the switching control strategy. Braking strength less demanding case, the electromagnetic brake can meet the needs of some of the braking force, thereby improving the friction braking conditions.
