基于设计参数的转向特性虚拟试验及评价

Evaluation and Stimulated Test of Steering Performance Based on Designed Parameters

基于新开发车型的设计参数,计算稳定性因数,估算汽车转向性能,提出增加横向稳定杆的改进方案。在ADAMS中建立改进后的虚拟仿真动力学模型,通过稳态回转虚拟试验进行验证,结果表明汽车的不足转向度增加,稳态转向特性得到优化。

Stability factor was calculated based on the design parameters of a new car to estimate the steering performance. Improvement method that a anti-roll bar was increased was proposed. A new dynamical model was established in ADAMS. A virtual steady static circular test was conducted to verify it. The result shows that the degree of under steer is improved which means steady turning performance is optimized.
