过山车轨道虚拟建模研究

In order to deal with the need to calculate the dynamics and kinetics parameters manually during the traditional designing process of roller coasters, the dynamic simulation method of roller coaster based on virtual simulation technology is studied in this paper. With the utilization of blend sweep function in Pro/E and ADAMS spline technology, the 3D track model of roller coaster is established, as well as the settlement of the crucial technology in virtual prototyping simulation of roller coaster. The influences of points selection to the movement and forces analysis of roller coasters during the construction of track spline is also mentioned in this paper. The results provide a basis to the improvement of design and safety of roller coasters.
