摘    要:针对采用独立轮毂电机驱动的新型海底铰接式复合轮式行驶机构,研究其在水平路面转向过程中各驱动轮的相对转速关系,为各驱动轮电机在转向工况下的转速输出控制策略提供了理论依据;利用虚拟样机仿真模型模拟该行驶机构通过不同高度的台阶、越过壕沟及爬坡时的运行过程,得出各驱动轮电机的转矩输出特性;根据驱动轮组中各个车轮对地面正压力的变化规律,确定在不同越障工况下各驱动轮电机的转矩控制策略依据。

Abstract: Based on a new type multi wheels travel mechanism driven by hub motors in deep sea environment, the velocity relationship of the driving wheels was studied when the articulated body was steering on flat road, which provided scientific basis for each hub motor speed control rule while steering. Virtual prototype was used to simulate processes of crossing obstacles and slope climbing. The torque output character of each motor was obtained and analyzed. According bearing force change law of each wheel, the basis for torque control strategy in these cases was determined.
