摘　　要：为了研究绕“S”行走无碳小车的运动特性与解决方案,在基于曲柄滑块的无碳小车转向机构上进行了创新设计,提出“余弦-摆杆”机构,利用SolidWorks软件进行无碳小车建模,并对MATLAB软件迭代算法进行了优化,分析小车的微调结构及几何参数,得出了应对加工及装配误差的小车整体设计方案。优化后的无碳小车能在很大程度上实现预先的目标与需求,为无碳小车机构设计及路径模拟提供了思路,也为此后类似的设计以及调整提供了理论及实践基础。In order to study the motion characteristics and solution of the“S”tracked carbon-free car,an innovative design on the steering mechanism of the car based on the crank slide mechanism is carried out in this paper.The“cosine-pendulum mechanism”was proposed and 3D modeling was established using SolidWworks.Besides,the iterative algorithm was optimized using MATLAB to analyze the geometric parameters and the way of fine-tuning,and finally came out the design proposal of dealing with machining and assembly errors of the carbon-free car.The optimized carbon-free car can meet the requirements properly and provide a theoretical and practical basis for similar designs.
