摘要
用多体动力学仿真软件ADAMS/Car分别建立了车辆模型、道路模型和车-路耦合模型,通过改变路面的附着系数,仿真了弯道路面附着系数对行车安全的影响。通过对侧滑角、后轮所受侧向力、垂向力的分析得出路面附着系数对弯道行车安全有着很大的影响。仿真结果显示:附着系数越小车辆在弯道行驶时越容易发生侧滑的危险;降低车速是减少雨天车辆弯道侧滑的有效方法。
In order to research the influence of tire-road friction coefficient on running safety, vehicle dynamics model, road model and vehicle-road coupling model were set up by using muhi-body dynamics software ADAMS/Car. It can be found that tire-road friction coefficient for the curve has a great impact on traffic safety by analyzing the side-slip angle, lateral force and vertical force on rear wheel. Computation result indicates that the smaller the tire-road friction coefficient, the bigger the risk of skidding the vehicle driving on the curve; reducing the speed of the vehicle is an effective method to avoid the side slip in rainy day.
