摘　　要：车辆高速行驶时的中心区操纵稳定性受到越来越多的关注,中心区"路感"是评价该性能的重要依据。转向系统是影响中心区操纵稳定性的关键系统,本文基于多体力学软件ADAMS建立了包含传动比、干摩擦、刚度等环节的转向系统,并嵌入整车模型中,通过改变相应参数,研究其对中心区操纵稳定性的影响,从而为车辆性能的完善提供一定的参考依据。On-center handling performance for high speed vehicle is becoming more and more concerned. Road feel is the most index to evaluate the on-center handling performance. Steering system is the key part of the whole vehicle which affects the performance,which includes steer ratio, dry friction and stiffness etc. In this paper, steering system model is set up by ADAMS, and embed into the whole vehicle model to study the effects of these nonlinearities on on-center handling performance.

关 键 词：中心区操纵稳定性 路感 转向系统 非线性环节
