Abstract

The objective of this research work is to analyze dynamic behavior of farm tractor passing over sine wave bump when the both side of the tires are passing through simultaneously. The model was formulated more effectively to express actual tractor motions by considering tire effective radius. And the tire stiffness that affects strongly to tractor motions were measured and evaluated by three methods.
