铰接轮式车辆的转向阻力矩分析难以简单地应用汽车或拖拉机偏转导向轮转向阻力矩的计算方法,而铰接车辆的前、后车段相对偏转时,车轮相对地面都存在不可忽略的运动。本文主要讨论二段式铰接底盘原地转向时,轮胎与地面之间的阻力矩引起的整机转向阻力矩,运用运动与力平衡一致性原理,编制了计算程序,对运动及力平衡进行对应的多维搜索,最终求得数值解。
The analysis of the steering resistance moment of hinged wheeled vehicle is difficult to simply apply the method of calculating the steering resistance torque of the steering wheel of the vehicle or tractor. However, when the front and rear sections of the articulated vehicle are relatively deflected, the wheels can not ignore the relative ground movement. This article mainly discusses the two-stage articulated chassis in situ steering, the resistance torque between the tire and the ground caused by the resistance torque of the whole machine, the use of motion and force balance consistent principle, the preparation of a calculation program to exercise and force balance Multidimensional search, the final solution of numerical solution.
