摘　　要：针对国内研制的微型观光旅游电动汽车在行驶时产生振动,使人体感到很不舒适的情况,以唐山市电动汽车重点实验室前期研制的微型观光旅游电动汽车为基础,应用多体动力学理论,在ADAMS/Car汽车专用模块中建立整车多体动力学模型。采用ADAMS/Car Ride专用模块提供的路面生成工具,生成以Sayers经验模型为基础的路面,使整车模型在常用车速下进行随机路面的平顺性仿真。对仿真得到的微型观光旅游电动汽车质心处加权加速度均方根值进行分析和评价,为进一步对此型号微型观光旅游电动汽车平顺性的优化及其他性能的提高打下良好的基础,为其实际生产起到很重要的技术性指导作用。Aiming at the situation that the vibration of the micro tourism electric vehicles which are made in do- mestic can make people feel uncomfortable, based on the micro tourism electric vehicle of Tangshan electric vehicle key laboratory, application of multi body dynamics theory, a full vehicle multi-body dynamics model in the special module of ADAMS/Car is build. Using the road generation tool which is provided by ADAMS/Car ride, generate the pavement which is based on Sayers empirical model, then let the full vehicle to run in common speed on the random road to simulate the ride comfort. Analysizing and evaluating the micro tourism electric vehicle weighted ac- celeration RMS simulation, lay a good foundation for this mini tourism electric vehicle ride comfort further optimiza- tion an performance improvement. It will play an important role in guiding the actual production.
