Abstract: To seek a track which consumes less energy for a wheel loader in a digging process, the track equations of two kinds of ideal tracks, a beeline and a curve, are given according to experience and relevant literature. The tracks are transformed from right-angle-space coordinate to joint-space coordinate, and from joint-space coordinate to drive space through track planning and kinematics modeling for the type of ZL40 wheel loader in a digging process. The drive equations of the lift cylinder and tilt cylinder are obtained. The force acting on the bucket in a digging process is given. A simulation for the ZL40 wheel loader model is presented in ADAMS software. The simulation result shows that the beeline track consumes less energy than the curve track does while the same load is completed in the same time.
