【摘要】：针对山西省大学生工程训练综合能力竞赛的主题,设计了一种将重力势能转化为动能且自动绕行"8"字轨迹的小车。首先,通过Matlab软件模拟计算出小车绕行的最佳"8"字轨迹,根据轨迹的大小确定小车后轮直径和齿轮机构的传动比;然后,通过不完全齿轮和曲柄摇杆机构相结合来设计小车的自动换向系统,当不完全齿轮有齿部分和无齿部分周期性地进入啮合时,小车相应地绕行"8"字轨迹的非圆弧部分和圆弧部分;最后,采用UG NX软件对小车的各组成机构进行三维建模、装配及运动仿真。在仿真取得理想的效果后,对小车进行加工制作与调试。经过参加省赛的实践检验,证明了该机构设计的合理性。
[Abstract]:In view of the theme of the comprehensive ability competition of engineering training for college students in Shanxi Province, a car is designed to convert the potential energy of gravity into kinetic energy and automatically detour the track of "8" word. The best "8" word trajectory of the car is calculated by Matlab software, and the diameter of the rear wheel and the transmission ratio of the gear mechanism are determined according to the size of the track. Then, an automatic reversing system is designed through the combination of incomplete gear and crank rocker mechanism, when the incomplete gear has teeth and the toothless part periodically enters meshing. The car correspondingly detours the non-arc part and the circular part of the "8" character track; Finally, the UG NX software is used to model, assemble and simulate the components of the vehicle. The manufacture and debugging of the trolley are carried out, and the rationality of the design of the organization is proved by the practice of participating in the provincial race.
