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.
