摘要

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。

Abstract

To study the motion characteristics of S-typed trajectory carbon-free car,and thus to optimize the design and adjustment.Through using the steering link mechanism to achieve carbon-free car S-type trajectory motion characteristic of the steering mechanism,the mathematical model of the relationship between the crank angle and the angle of the front wheels is built and its steering mechanism characteristics simulation is carried out by using MATLAB,the relation diagram of crank angle and the front corner of the is obtained.The mathematical model of the car trajectory is established,the parameters influence on the motion trajectory and their influence law are obtained,the relevant amount of the trajectory amplitude value is found and trajectory motion simulation of the car is carried out by using MATLAB.Eventually,the optimal cosine trajectory with the pile of 0.9 m,the amplitude of 0.095 m is got,the crank length is 21 mm at this time,a theoretical guidance for S-type carbon-free car design and adjustment is provided.
