摘　　要：近年来,无碳小车比赛越来越被大众所知,且赛道路径也趋于复杂。基于此,文中采用理论力学中的速度瞬心概念,结合机械结构建立了一个数学模型,并提炼出具有理论支撑的算法,通过凸轮储存转弯信息,并通过SolidWorks软件进行了仿真验证。该方法可以为后续比赛提供原理上的解决方案。文中提炼出的算法具有一定的通用性,可以应用到其他如路线规划的类似问题中。In recent years,race of carbon-free car has become more and more known to the public,and the track has become more complicated.On this basis this paper uses the concept of the instantaneous center of speed in theoretical mechanics,combined with the mechanical structure to establish a mathematical model and extract a theoretically supported algorithm.The track information is stored by the cam,and the simulation is verified by SolidWorks.This method can provide a theoretical solution for subsequent competitions,and the algorithm is universal that can be applied to other similar problems such as route planning.
