过山车动态仿真建模方法研究

随着过山车速度及运动复杂性不断提高,其研制过程的动力学分析、安全评价愈显重要,传统方法已很难满足要求。采用虚拟样机技术和图形学方法对轨道模型、车辆拓扑结构以及轮轨关系等过山车动力学建模中的关键问题进行研究,并在ADAMS软件中实现。通过仿真分析,在设计阶段就可获得过山车在不同工况下运行时各部件的速度、加速度及载荷变化曲线,为进一步的强度校核、安全性分析提供可靠依据。

Research on Roller Coaster Dynamic Modeling and Simulation

The dynamic analysis and safety evaluation is important during the period of developing a roller coaster for its high speed and complex motion. The traditional methods cannot meet the needs. The modeling methods of the rail track and vehicle of the roller coaster were researched by the virtual prototyping technology and graphics theories. A virtual prototype model of a roller coaster was built in ADAMS software. Velocity, acceleration and force curves of the roller coaster under different work conditions were gained through dynamic simulation. These are essential for its strength verification and safety analysis.
