摘　　要：建立了客车操纵动力学仿真模型,根据仿真结果分析了影响稳态转向特性的主要因素.用中性转向点侧向加速度、不足转向度和车厢侧倾度三个评价指标对稳态转向特性评价计分,并根据计分值对悬架和轮胎参数进行调整以改善客车的操纵性能.Vehicle's steady state cornering performance (oversteer / understeer) has substantial influence on its handling and stability. Main factors affecting this performance are analyzed based on modeling of coach HFF6850 for simulation of the handling dynamics by ADAM. The steady state cornering performance is appraised by scoring of three indicatives, i.e. lateral acceleration at neutral steering point, understeer rate, and roll rate of the vehicle body, and then comprehensive scores are calculated. Suspension and tire parameters are adjusted according to the comprehensive scores to improve the coach's handling performance.
