根据第五届全国大学生工程实训大赛的要求,设计并制作基于圆柱凸轮结构的"8字形"无碳小车。根据规划的无碳小车理论轨迹,对小车的传动机构和转向机构进行了设计和参数计算,得出了小车的运动方程,结合SolidWorks中的Motion分析对小车运动轨迹进行仿真,并对圆柱凸轮等关键参数进行优化。试验结果表明,该无碳小车能完成11次"8字形"寻迹运动,实现了按预定轨迹行走的目的,验证了该机构的合理性。

According to the requirements of the Fifth National College Students' Comprehensive Ability Competition in Engineering Training, the design and production of cam structure based on the 8-shaped carbon-free car is completed. According to the theoretical trajectory of the carbon-free car, the design and parameter calculation of the transmission mechanism and the steering mechanism of the car are carried out. The kinematic equation of the car is obtained, and the motion trajectory of the car is simulated according to Motion analysis in SolidWorks. Parameters such as cylindrical cam are optimized....
