摘　　要：为了提高越野汽车的平顺性,针对越野汽车的使用环境和特点,参照发达国家的相关规范,对越野汽车平顺性的工况确定及评价指标进行讨论,分析我国目前在该领域存在的不足,并提出相关建议。在对某一越野汽车进行理论分析和试验的基础上,验证了采用多工况方法进行平顺性分析和考核的可行性。采用多体动力学分析的方法建立了整车平顺性分析模型,结果表明理论分析与试验结果的误差较小,对改善越野汽车的平顺性具有重要的指导意义。The determination of working conditions and the evaluation indicators were discussed for offroad vehicles to improve the ride performance according to the characteristics of the driving conditions. The related specifications in the developed countries were referenced. The problems of current methods are pointed out and some suggestions were proposed. Based on the theoretical analysis and test data, the feasibility of using multi-working conditions was verified. Multibody dynamics was applied to set up the whole vehicle ride performance model. The results show very little difference between the theoretical results and test results. Therefore the model is important to improve the ride performance.
