【Abstract】 Based on the 3-DOF kinematics model of wheel loader, the kinematics analysis is carried out, and two kinds of scooping trajectories (including position/orientation, velocity and acceleration,), called triangle type and trapezoid type respectively, were discussed both in joint space and Descartes space. With numerical simulation, the dynamic resistance of bucket, which is produced by the material in bucket, was investigated. It shows that the dynamic resistance is less than 10% of vertical statistic resistance.更多还原
