摘　　要：采用虚拟样机技术建立过山车轨道与列车模型并进行运行仿真,保证了数字样机符合游乐设施安全规范要求,但是在进行过山车实际安装过程中,难以保证物理样机与数字模型完全一致,在实际工况下与仿真运行结果也会有一定的偏差,因此必须对物理样机进行测试,依据采集的数据应用Matlab进行分析,找出不合格数据点,判断不合格数据点的位置,指导设计人员针对性的改进过山车轨道,并进行反复检测分析与调整轨道,直到达到安全标准的要求。Virtual prototype technology was adopted to establish the model of a roller coaster track and train. Then the operation simulation was done with the model to ensure the digital prototype to meet the requirements of the safety standard of entertainment equipment. But in the actual installation process of a roller coaster,it was difficult to guarantee the physical prototype and its digital model to agree well,the operation state under the actual working condition and the simulation result had a certain deviation. The physical prototype was tested to measure its accelerations. The acceleration data collected were analyzed with Matlab to find out unqualified data points,and judge their locations. The designers were guided to improve pertinently the roller coaster track with repeatedly tests and analyses,and adjusting the track until it met the requirements of the safety standard.
