ABSTRACT
According to design requirements, the total length of the roller coaster orbit is 567 m, the maximum height of the roller coaster orbit is 30 m, the distance of two orbits is 960 mm, and the maximum running speed is 80 km/h. As shown in Figure 2, two space curves were used to simulate the roller coaster orbit in the global coordinate system of ADAMS. The orbit is mainly composed of the platform, the lifting section, the transition section, the floating ring, the vertical ring, and the spiral
the traction of the carrying car, and the wind loads (Li, 2009; Tian, 2006; He, 2006). In order to ensure the accuracy of the simulation data collection, the sampling frequency must be more than 20 Hz according to the sampling theory, i.e. the simulation step’s length must be less than 0.05. Considering the computer performance and the simulation time, the simulation step length was set to 0.01.
