摘　　要：根据大学生工程训练大赛的参赛要求,在结构设计上选择了曲柄滑块机构来控制无碳小车的运行方向,利用螺杆进行位移补偿,使运行轨迹近似于正弦曲线,从而达到避障的目的。通过构建小车的三维模型,进行结构优化,分析了小车运行轨迹并制作出实物,经运行测试,小车性能达到设计要求。According to the requirements of the competition of engineering training for college students,the crank-slider mechanism is selected to control the running direction of the carbon-free car in the structural design,and the displacement compensation of the screw is used to make its running track approximate cosine curve,so as to avoid obstacles.Through the construction of three-dimensional model of the car,structural optimization is carried out,the trajectory of the car and the production of a physical object is analyzed.Running test proves that the car performance can meet the design requirements.
