开环轨迹太阳能小车设计与仿真分析
Design and simulation analysis of open-loop trajectory solar-powered car
摘要
Abstract
To meet the requirements for open-loop trajectory motion of a solar-powered car,a design and fabrication method was proposed for a solar-powered car.Firstly,by using B-spline curves,the characteristic points were fitted to generate an ideal open-loop trajectory curve.MATLAB software was then utilized to analyze and optimize the planned trajectory to produce the cam profile.Next,based on the overall functional requirements,the overall structure,transmission mechanism,and steering fine-tuning mechanism of the solar-powered car were designed.Subsequently,simulation software was employed to perform simulation analysis and optimization of the cam trajectory,and the car's circuit modules were assembled.Finally,actual driving tests of the car were conducted.To improve the trajectory accuracy of the car,the front wheel offset angle was modified by adjusting the fine-tuning mechanism.Experimental results demonstrate that the car fabricated using this method operates stably and successfully passes through all predetermined characteristic points.关键词
