对轮式拖拉机的转向过程进行了动力学分析,详细探讨了影响该阻力矩的因素,以JS―754拖拉机为例,推导了在不同地面条件下原地稳定转向时的转向阻力矩;结合拖拉机转向机构的特性,计算了稳定转向工况下转向活塞杆的推力,并实车测定了转向油缸的推力。结果表明转向油缸推力的理论分析与实测值是一致的,这为拖拉机线控液压转向的路感控制提供了理论与实用依据。

When a wheeled tractor makes a steering process, the dynamics is analyzed. The factors which affect the resistant torque are inquired. The static turn resistant torque in different ground conditions is calculated for JS-754 model tractor. The thrust of the steering piston rod is calculated according to features of the tractor steering mechanism. Also the thrust is measured in the tractor. The test result shows that the theoretical thrust of the steering piston rod is consistent with the actual thrust. This will provide a basis to design the road sensing for the tractor’ s hydraulic steering by-wire system.
