摘　　要：过山车相对轨道做高速运动,其动态响应对过山车的舒适性、安全性有重要影响.利用ADAMS建立过山车动力学模型,对其进行了动力学仿真分析,阐述了建立过山车动力学分析模型的关键问题处理方法,并进行正常风速下的动力学分析.分析比较了风速对过山车动力学运动速度的影响.过山车的整个运动过程仿真分析速度结果与实际实验测试结果误差在6.4%以内,表明模型是合理的.With regard to the high-speed movement against the track,the dynamic response of roller coaster significantly impacts on its comfortableness and safety.By using ADAMSTM to establish the dynamical models,the dynamical simulation analysis is conducted,mainly including the vital problems of dynamical analysis model establishment;the dynamical analysis under normal wind speeds;and the impact comparison and analysis of wind speeds upon movement speeds.From the simulation analysis results,it is found that the simulated model for roller coasters is reasonable.In particular,the error between simulated and tested speeds is below 6.4%.
