摘要
四轮底盘在小地块水田作业时,减少地头空行转弯时间是提高作业时间利用率的重要环节。为实现四轮底盘小半径转弯,以提高水田播插底盘作业率为主要研究目标,对四轮底盘在90°、180°等不同转弯形式下进行分析,得出适合小地块水稻播插作业时以较小转弯半径的转弯方式;前桥摆转四轮底盘在转向时,通过控制前桥驱动轮的转动,使前驱动桥主动围绕着转向装置转动,可以带动底盘以任意角度转向。采用ADAMS软件对四轮底盘后轮轨迹进行模拟,在确保后轮完全不吃入已完成作业区的倒U转弯方式的情况下,提出设计前桥摆转式四轮底盘转向系统的可行性。
Four-wheel chassis when working in a small piece of paddy field, reduce blank line turning time is an important link in work utilization rate operation time. In this paper, in order to realize four-wheel chassis small turning radius, increase the paddy field on chassis operation efficiency as the main research target, 90°,180° in the four-wheel chassis under different forms of turning modeling analysis, and concluded that suitable turning way of smaller turning radius for small plot rice sowing operations; When the front axle Swing four-wheel chassis steering, By controlling the rotation of the front drive axle, to the front drive axle can rotate active around the steering device, and drive the chassis steering in an arbitrary Angle; Through ADAMS software for simulating four-wheel chassis rear wheel track, and ensuring the rear wheels do not enter that the assignments section has been completed, put forward to design front axle pendulum type four-wheel chassis steering system operability.
