“双8”字无碳小车的轨迹分析和结构设计

The Trajectory Analysis and the Structure Design of "Double 8" Shape Carbon-free Car

本文设计了绕行"双8"字轨迹运行的无碳小车。通过绕行轨迹分析,计算出无碳小车的"双8"字轨迹理想长度。采用不完全齿轮和曲柄摇杆机构相结合的组合结构,完成了小车转向机构设计。计算出无碳小车参数,并采用MATLAB仿真运行轨迹,优化结构参数,完成无碳小车整体结构优化。最后,采用CREO软件完成了无碳小车的三维建模,装配,并对无碳小车进行加工制作与调试,小车能完整走出"双8"轨迹,证明了该组合转向结构的合理性。

A carbon-free car that bypasses the"double 8"shape trajectory was designed.The optimized"double 8"shape trajectory of the carbon-free car was calculated by the detour.Combination mechanism of incomplete gear and the crank rocker mechanism were used in the carbon-free trolley steering.The mathematical model was founded and optimized parameters of the overall structure of the carbon-free car was calculated by MATLAB software.Finally,the CREO software was used for three-dimensional modeling and assembling the various components of carbon-free car,the carbon-free car was processed and debugged,the rationality of the combined steering structure was proved.
