摘　　要：针对在进行过山车承载安全评价时,工程实际中一般采用在座椅上方特定位置添加质量块模拟加速度传感器进行仿真,难以真实反映乘客在乘坐过山车时的真实加速度响应的问题,提出通过虚拟样机技术,应用人体动力学仿真软件LifeMod建立数字人体模型,将人体坐姿模型与过山车座椅和安全压杠模型在ADAMS中进行耦合,进而将人椅耦合模型与轨道耦合,添加约束,施加载荷,进行动力学仿真。对仿真获得的人体模型加速度数据,以及人体模型不同部位在过山车运行过程中承受的反作用力大小进行分析,结果表明人体模型不同方向加速度与组合加速度符合安全规范要求,且在过山车运行过程人体模型的腿部相比较于头部和肩部承受的反作用力最大,验证了过山车乘载人体模型的合理性,为评估过山车安全性提供参考。In order to evaluate the safety of roller coasters, mass blocks are generally used to add a specific position above the seat to simulate the acceleration sensor in engineering practice, which is difficult to reflect the real acceleration response of passengers in the roller coaster. The digital human body model was established by using LifeMod, the human body dynamics simulation software, and the human sitting model was coupled with the roller coaster seat and safety compression bar model in ADAMS,and then the human-chair coupling model was coupled with the track, adding constraints and applying loads to carry out dynamics simulation. The acceleration data of the human body model obtained from the simulation and the reaction force suffered by different parts of the human body model during the operation of the roller coaster were analyzed. The results show that the acceleration in different directions and the combined acceleration of the human body model meet the requirements of safety specifications, and the reaction force borne by the legs of the human body model is the largest compared with the head and shoulder during the operation of the roller coaster. The rationality of the roller coaster mannequin is verified, which provides a reference for evaluating roller coaster safety.
