Abstract:

The paper gives dynamic equations of climbing over obstacles, judging standard of climbing over obstacles capability was proposed based on dynamic equations. State motion of vehicle is analyzed based on climbing over obstacles by single front wheel, driving torque of climbing obstacle was obtained, and its influential factors gravity allocation was analyzed. Finally, the simulation analysis gives conclusion the theory inference result is correct.

Key words: vehicle engineering, oscillating body, climbing obstacle, driving torque, center of gravity position
