摘　　要：为了研究随机路面对汽车平顺性的影响,文章采用多体动力学理论,基于ADAMS/Car建立某商用车的整车模型;介绍了汽车平顺性的评价方法;在随机B,C级路面输入下,以不同的行驶车速进行整车的平顺性仿真分析,结果表明:相对于随机C级路面,随机B级路面更能够有效地提高汽车的平顺性。该结论可为不同的路面激励对汽车平顺性的影响,提供理论依据和参考。In order to study how the random road surface affects the vehicle ride comfort, this paper adopts the theory of multibody dynamics to build a vehicle model with the software of ADAMS/Car. The paper introduces the evaluation method on ride comfort, with the input under the condition of the random B and C-grade road surface, vehicle ride comfort can be simulated and analyzed at different speed. The random B-grade road surface can further improve vehicle ride comfort compared with the random C-grade road surface.
