摘　　要：针对某款微型电动汽车平顺性不尽理想的情况,以实车参数为依据,应用多体系统动力学软件ADAMS建立包含人-座椅模型的微型电动汽车仿真模型。分别对实车及整车仿真模型完成相同频率及振幅的正弦激振试验,提取实车驾驶员座椅端面处及整车仿真模型人-座椅模型座椅端面处的时域信息进行对比分析,验证所建模型的正确性。最后,参照平顺性试验方法 GB/T 4970—2009完成整车不同车速满载工况、B级路面平顺性仿真试验,对该车行驶平顺性进行分析研究。结果证明,该微型电动汽车当车速超过50 km/h时,不具有理想的行驶平顺性能。Aiming at the ride comfort of a mini electric car is not ideals,with the real mini electric car parameters,full vehicle simulation model contains human-seat model is established based on dynamics software ADAMS.The same frequency and amplitude sine experimental study of real vehicle and simulation model are finished respectively,getting the domain information in the same place of the driver＇s seat to verify the authenticity of full vehicle simulation model by contrastive analysis of the domain information information. And conferring the standard of GB /T 4970—2009; ride comfort experiment is finished on B level road under different speed and full load condition.The simulation results indicate that when the mini electric car running at the exceed speed of 50 km / h,the mini electric car doesn＇t have good ride comfort.
