摘要
为了研究拖挂式房车的分配问题,建立拖挂式房车制动过程中的动力学模型,在Simulink中搭建了仿真模型、轮胎模型、滑移率模型。该方法很直观地展现了在不同的滑移率情况下拖挂式房车各轴地面制动力的关系。通过制动器制动力的速率来模拟紧急制动和缓慢制动情况,对比三轴制动抱死顺序以及地面制动力大小情况,验证了分配系数的合理性,同时为拖挂式房车防抱死制动系统研究提供了数据支持。
In order to study the problem of the distribution of trailer-type RVs,the dynamic model of the trailer-type RV’s braking process was established,and the simulation model,tire model and slip rate model were built in Simulink.This method intuitively shows the relationship between the ground braking force of each axle of the trailer RV under different slip rates.Simulate emergency braking and slow braking through the rate of brake braking force,compare the three-axis brake lock sequence and the ground brake force,verify the rationality of the distribution coefficient,and provide data support for the research of trailer RV anti-lock braking system.
