    为研究S型轨迹无碳小车的运动特性,进而对其进行优化设计及调整。通过对利用连杆机构实现转向的S型轨迹无碳小车转向机构的运动特性进行研究,建立了曲柄转角与前轮转角的数学关系模型,并利用MATLAB对其转向机构特性进行了仿真,得到了曲柄转角和前轮转角的关系图;建立了小车运动轨迹的数学模型,得到了影响运动轨迹的参数及其规律,找到了轨迹幅值的相关量,并利用MATLAB对小车运动轨迹进行了仿真。最终得到了桩距为0.9 m、幅值为0.095 m的最优余弦轨迹,此时曲柄长度为21 mm,为S型无碳小车的设计及调整提供了理论指导。 In order to study the motion characteristics of S-type trajectories without carbon car, and then to optimize the design and adjustment. Through the use of connecting rod mechanism to achieve the steering of the S-shaped track carless car steering mechanism movement

The mathematical relationship between the crank angle and the front wheel angle is established, and the characteristics of the steering mechanism are simulated by MATLAB. The crank angle and the front wheel angle

The mathematical model of the trajectory of the trolley is established, the parameters and their regularity of the trajectory are obtained, and the correlation quantity of the trajectory amplitude is found.

Trace of the simulation. Finally, the optimal cosine trajectory with a pitch of 0.9 m and an amplitude of 0.095 m is obtained. At this time, the crank length is 21 mm, which provides the design and adjustment of the S-type carbonless car.
