摘要：以凸轮机构作为传动，设计了一款针对S环型赛道的无碳小车结构，基于逆向设计思维并结合比赛路线要求设计出合理的凸轮轮廓的设计方法。基于控制变量法，在确定无碳小车基本结构的情况下，获取摆角随步数变化规律，继而获取推杆运动规律，同时参照给定赛道在MATLAB平台不断调整，直至获取最佳参数与对应的最优推杆运动规律，最终推导出凸轮轮廓。实验表明，该方法操作难度适中，可行性强，可推广到其它较为复杂的赛道中去，为后续无碳小车的设计工作提供了一定的理论与技术支持。

Abstract：The National College Students' engineering training comprehensive ability competition is held every two years to improve college students' engineering innovation consciousness, practical ability and teamwork spirit, and promote the cultivation of innovative talents. The carbon-free car competition is a standing event in the competition. For the more complex track, it is more appropriate to use the cam mechanism as the trolley transmission mechanism. Designing a reasonable cam profile according to the requirements of each competition is the key to the accurate walking of the trolley. Based on reverse design thinking, a carbon-free car structure for the S-ring track is designed in this paper. The design steps have clear objectives and strong operability: base on the control variable method, after determining the basic structure of the carbon-free car, obtain the variation law of the swing angle with the number of steps, and then obtain the push rod motion law; at the same time, concerning the given track of the competition, continuously adjust it on the MATLAB platform until the optimal parameters and the corresponding optimal push rod motion law are obtained, and finally deduce the cam contour. The experiment shows that this method has moderate operation difficulty and strong feasibility, and can be extended to other complex tracks, which provides a certain theoretical and technical support for the subsequent design of carbon-free cars.
