摘要： A gravity-powered toy vehicle, such as a model roller coaster, with an energy-storing flywheel coupled to the wheels to reduce the vehicle velocity so it approaches that which is proportionately realistic for the model scale. The initial potential energy of the vehicle is mostly conserved over the course of the track just as with a real roller coaster. At all points on the track the velocity of the model vehicle is reduced by a constant proportion compared to an unrestrained free-fall vehicle. Thus the dynamic velocity profile of the toy vehicle is the same as for a full size vehicle throughout its descending and ascending journey, but at a proportionately reduced speed.
摘要翻译：重力动力的玩具车，例如模型过山车，具有耦合到车轮的储能飞轮，以减小车辆速度，使其接近对于模型规模成比例地实际的飞行器。车辆的初始势能在轨道上大部分保守，就像真正的过山车一样。在轨道上的所有点上，与无限制的自由落体车辆相比，模型车辆的速度减少了一定的比例。因此，玩具车辆的动态速度分布与其在整个降序和上升行程中的全尺寸车辆相同，但是速度相对降低。
