摘　　要：针对某纯电动汽车,在整车轴距、车身大小等基础参数不变的情况下,分析研究车轮偏距对车辆动力学性能的影响;结合基本理论原理,对在不同车轮偏距下车辆动力学性能的表现进行主观评价,并利用测试设备进行客观测试。结果表明:在整车其他基础参数不变的情况下,随着车轮偏距的逐渐减小,会加剧车辆行驶控制性和稳定性的衰退,主观评价与客观测试结果基本保持一致。For electrical vehicle,wheel offset influence on the vehicle dynamics is analyzed and studied under the circumstance that wheel-base、body size and other parameters keep unchanging;Vehicle dynamics performance under different wheel offset is subjective evaluated and objective tested with test facilities according to the basic theory.The results show that vehicle driving controllability and stability degradation is deepened with the decrease of wheel offset when other basic parameters are unchanged.Subjective evaluation is consistent with the objective test results basically.
