摘要
为了研究车辆侧翻风险因素对车辆侧翻的影响程度,运用ADAMS/Car软件建立了某轿车的多体动力学模型,基于仿真分析的方法进行了鱼钩转向侧翻试验设计,并选取横向载荷转移率作为度量车辆侧翻风险的指标。通过正交试验的方法,研究了路面摩擦系数、车辆行驶速度、方向盘角速度以及质心高度对车辆侧翻的影响程度。结果表明,在给定的水平下影响车辆侧翻的因素按其影响的强弱程度依次为:车辆行驶速度、路面摩擦系数、质心高度、方向盘角速度,其中车辆行驶速度对车辆的侧翻具有显著性影响。
In order to study the influence degree of rollover risk factors on vehicle rollover, a multi-body dynamics model of a car is built by using ADAMS/Car software. The fishhook rollover test is designed based on simulation method, and lateral load transfer ratio is selected to measure vehicle rollover risk. The influence degrees of road friction coefficient, vehicle speed, angular velocity of the steering wheel and centroid height on vehicle rollover are studied by using the orthogonal experiment method. The results show that under the given level, the significance of the influencing factors can be ranked as follows ： vehicle speed, road friction coefficient, centroid height of vehicle and angular velocity of steering wheel, among them vehicle speed has great influence on vehicle rollover.
