摘要
为了研究轮胎不同的扁平比对同一款车型操控性能差异的影响,首先用Carsim仿真软件模拟路况动态仿真和输出相关参数曲线,与真实操控车辆所得的数据进行比对后得到了质心侧偏角、横摆角速度和侧向加速度响应曲线,最终对获得的数据进行分析和偏差检验,得到信度较高的客观评价结果,可以为主机厂评价轮胎滑移特性提供一种验证手段。
In order to study the impact of different tire flatness ratios on the difference in handling performance of the same model,the Carsim simulation software was first used to simulate the dynamic simulation of road conditions and the output related parameter curve was compared with the data obtained from the actual control of the vehicle.Swing angular velocity and lateral acceleration response curves,and finally analyze and check the deviation of the obtained data,and obtain objective evaluation results with high reliability,which can provide a verification method for the OEM to evaluate the tire slip characteristics.
