Abstract Vehicle vibration influences human riding comfort directly. In order to evaluate human riding comfort (HRC) of human-vehicle systems in vibration environment efficiently, a biomechanical simulation model of human-vehicle systems was constructed in the ADAMS/View and LifeMOD. By simulating road roughness and inputting the road surfaces as a vibration excitation to human-vehicle systems, the simulation research on HRC was carried out on different roads and at various speeds. Then the human vibration experiments were done on the SA30-S802/ST random vibration table to verify the results of the simulations. Through comparison, it was concluded that the simulation result agreed with the experimental data generally, which verifies the correctness of the biomechanical simulation model of human-vehicle systems and reliability of simulation on HRC to some degree. The research has certain reference value for rapidly evaluating HRC of human-vehicle systems and provides efficient methods to forecast and evaluate HRC at the stage of vehicle design．

人-车系统的人体乘坐舒适性仿真及实验研究
汽车振动直接影响人体的乘坐舒适性.为了高效地评价振动环境下人-车系统的人体乘坐舒适性,运用ADAMS/View和LifeMOD软件构建了人-车系统生物力学仿真模型,通过对路面不平度的模拟,将不同路面作为振动激励添加到人-车系统的动力学分析当中,进行不同路面及不同车速的人体乘坐舒适性仿真研究.在SA30-S802/ST随机振动台上,进行相应路面及车速激励的人体振动响实验,并验证了人体乘坐舒适性.将仿真计算与实验结果进行对比研究表明,仿真结果和实验结果基本一致,一定程度验证了所建立的人-车系统生物力学仿真模型的正确性及其进行人体乘坐舒适性仿真的可靠性,对快速评价人-车系统的人体乘坐舒适性具有一定的指导价值,为在汽车产品的设计阶段进行人体乘坐舒适性预测和评价提供了有效方法.
