基于横向稳定杆的汽车操纵稳定性影响分析

文章基于横向稳定杆在整车的功能,分析车辆安装横向稳定杆和不安装横向稳定杆两个状态,研究了横向稳定杆对车辆操稳性能的影响,进一步在Trucksim软件中建立虚拟整车和驾驶员模型,模拟稳态回转和蛇形试验工况,并结合试验评价标准进行评分,对比分析结果表明,安装横向稳定杆的车辆对不足转向和车辆侧倾度性能影响较大,对转向性能影响较小。

Analysis of the Influence of Vehicle Handling and Stability Based on the Stabilizer Bar

Based on the function of the stabilizer bar in the whole vehicle,this paper analyzes the two states of installing the stabilizer bar and not installing the stabilizer bar,studies the influence of the stabilizer bar on the vehicle handling and stability performance,further establishes the virtual vehicle and driver model in the trucksim software,simulates the steady-state rotation and serpentine test conditions,scores and compares the results with the test evaluation criteria The results show that the performance of the vehicle with the stabilizer has great influence on understeer and vehicle roll,but has little effect on the steering performance.
