摘　　要：以丛林飞车为例,通过理论计算和虚拟样机技术,模拟滑行最大速度在不同摩擦系数下的仿真结果,表明轮轨系统的摩擦系数对丛林飞车的速度影响至关重要,讨论了滚动摩擦产生的机理,同时分析了影响摩擦系数的因素,根据力矩平衡推导出滚动摩擦系数的计算公式,说明滚动摩擦阻力不仅与法向载荷有关,而且与滚动体的材料、硬度及轮子半径等因素有关,为滑行车类游乐设施速度计算提供参考。Taking the jungle flying as an example, the theoretical calculation and virtual prototyping technology are used to simulate results of the maximum speed under different friction coefficients, show that the friction coefficient is crucial to the speed of the jungle speed, explore the mechanism of rolling friction, and the influence of friction coefficient Factors were analyzed. The calculation formula of the rolling friction coefficient is derived according to the moment balance, which indicates that the rolling frictional resistance is not only related to the normal load, but also related to the material, hardness and wheel radius of the rolling element, which provides a reference for the speed calculation of scooter type rides.
