摘要
综合考虑重型商用车横向稳定杆角刚度、轮胎垂直刚度和悬架组合角刚度等因素,建立了静态侧翻简化数学模型,计算出商用车的静态侧倾稳定角。基于ADAMS建立了商用车整车的刚柔耦合模型及翻转试验台,完成了模型求解。将模型结果与实车测试结果进行对比,结果表明:两者误差控制在1.4%。最后应用该数学模型分析重型商用车侧倾稳定角关键影响因素的主要参数。
A simplified mathematical model for static rollover of a heavy commercial vehicle is established, which can take into account the angle stiffness of anti-roll bar, the vertical stiffness of tire and the combined angular stiffness of the suspension, and the static roll stability angle of commercial vehicle is derived and calculated. At the same time, based on ADAMS, a rigid-flexible coupling model of commercial vehicle and a turning test bed are established to solve the model. The results of model simulation and real vehicle test are compared and analyzed. The results show that the error of the two models is controlled below 1.4%. Finally, the model is applied to analyze the key influencing factors affecting the roll stability angle of commercial vehicles.
