摘　　要：为提高无碳小车"S"形运行轨迹对称性,对整车进行了运动机构设计,建立转向机构数学优化模型,利用Matlab优化工具箱优化其相关参数,并探讨参数变化对轨迹对称性的影响。通过ADAMS仿真验证了优化后参数的正确性,轨迹对称度理论上达到96%以上。在实车试验中小车能够完成20个绕桩动作,表明了优化后机构的合理性。In order to improve the track symmetry of carbon-free car for‘S’shape,the movement mechanism of the car is designed,the mathematical optimization model of the steering mechanism is built,and the relevant parameter is optimized by using the Matlab Optimization Tools,the influence between parameter and track symmetry is discussed.The accuracy of the optimized parameter is confirmed by ADAMS simulation,the track symmetry achieved 96% theoretically.The test shows that the car can avoid 20 obstacles which verified the rationality of the mechanism.
