履带车辆转向时最大驱动力矩的计算

履带车辆转向时不仅要克服行走阻力，还要克服转向阻力，该文对不考虑车体重心偏移时的转向驱动力矩进行了研究，并在此基础上着重研究了考虑重心偏移时的转向驱动力矩的计算方法，进行了实例计算和比较分析，可知横向偏心距对总的转向阻力矩没有影响，而纵向偏心距对其有影响，且随纵向偏心距的增加转向阻力矩减小；只考虑纵向偏心距，而不考虑横向偏心距时，转向时驱动力矩小于不考虑重心偏移时的驱动力矩；当只考虑横向偏心距，而不考虑纵向偏心距时，转向驱动力矩最大。当履带车辆原地转向，且只存在横向偏心距时靠近偏心一侧的履带的驱动力矩最大。

Method for calculating maximum tractive torque of tracked vehicle while steering

Tracked vehicle need to overcome not only longitudinal resistance but also lateral resistance during turning. Based on the study on that of having no center gravity offset, tractive torque were determined while having center gravity offset. Through comparative analysis and example calculation, conclusions could be drawn that the lateral center gravity offset had no effect on the gross turning resistance, but the longitudinal offset had great effects on it. With the increase of the longitudinal offset, the turning resistance decreased. The minimum tractive torque was acquired while longitudinal offset was only considered and the maximum was acquired while the lateral offset was only considered. The track which is nearer to the lateral center gravity offset has the most tractive torque while two tracks rotate to the opposite direction.
