汽车后轴侧滑动态特性及稳定性研究

本文建立了汽车在制动时后轮抱死侧滑的力学模型，分析了汽车后轴侧滑的运动规律及其动态特性，结合汽车前后累的制动比例关系，通过计算机求解出了在汽车紧急制动时保证侧滑相对稳定的参数允许变化区域，为提高汽车的制动稳定性提供了一种有效的计算和分析方法。

Research on Skid Characteristics and Stability of Vehicle Rear Axles

A mathematical model has been developed to discribe the skid characteristics of a vehicle with rear wheels locking up ahead of front wheels. Based on the model, the angular deviation representing the skid movement is obtained and the effects of various factors are analysed. In addition, a critical measure, the time lag between front and rear wheel locking and its sensitivity to parameter variation is discussed. Finally, parameter margins for assuring relative skid stability are proposed.
