摘要：

为有效分析重载车辆的转向安全性,利用拉格朗日方法建立了整车转向模型和侧向平衡方程,定义侧翻余量和侧滑余量,并对侧翻和侧滑的顺序进行判定。在此基础上分析了路面横向附着系数等因素与车辆转向时侧向平衡性的关系,并进一步揭示了重载车辆侧倾和横摆惯性积对稳定性的影响。最后对某型实际重载车辆的转向特性进行了仿真验证,发现路面横向附着系数主要影响侧滑,车身质心高度和轮距宽度的比值主要影响侧翻,惯性积会影响系统的稳定性。

关键词: 重载车辆, 侧滑, 侧翻, 安全性分析

Abstract:

In order to analyze effectively the turning safety of heavy vehicles, the dynamic model and lateral balance equations of the whole vehicle were established by using the Lagrange method. The allowance of sideslip and rollover were defined, and the sequences of rollover and sideslip were determined.Based on the above analysis, the influence of the factors such as cross road adhesion coefficient to the lateral stability were analyzed, Moreover, the influence of roll-yaw inertia on the stability was further investigated. Finally, the turning characteristics of a heavy vehicle were simulated. It was found that the sideslip is mainly affected by the cross road adhesion coefficient, the rollover is mainly affected by the ratio between mass-center height and vehicle width, and the stability of the model is affected by the product of inertia.

Key words: heavy vehicle, sideslip, rollover, safety anylysis
