某轿车操纵稳定性客观试验方法及评价

A Car Handling Stability Objective Test Method and Evaluation

文章主要通过对车辆的操作稳定性试验进行测试,根据8项操纵稳定性客观试验,从而为改善汽车的操纵稳定性、提高车辆的安全性提供依据。通过客观试验原地转向、滚动转向、斜坡制动、On Center(方向盘中间位置转向)、稳态回转、扫频转向、双移线、角阶跃等试验方法得到该样车操稳性能各个方面的关键参数和曲线。基于这些数据,可以对该样车各项操稳性能进行评判,得出结论为该车具备不足转向的特性,为该车型的操稳性能的优化提供依据,同时可为底盘调教提供数据支持,最终为车辆稳定性和安全性提升奠定基础,从而提高该车型的操作稳定性和安全性。

This article mainly tests the operation stability test of the vehicle,according to 8 operation objective stability tests,so as to provide a basis for improving the operation stability of the vehicle and improving the safety of the vehicle.Through the objective test of in-situ steering,rolling steering,slope braking,On Center(steering wheel middle position steering),steady state rotation,sweep steering,double shift line,angular step and other test methods to obtain the key parameters and curves of the sample vehicle stability performance.Based on these data,can judge the sample car each hold steady performance,concluded that the car has the characteristics of the steering,operation of the steady performance optimization basis,for the model can provide data support for the chassis adjustment,eventually lay the foundation for vehicle stability and safety,so as to improve the operation stability and safety of the model.
