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.
