A picking arm model is established using three-dimension entity software Pro/E and the kinematics analysis and forward and reverse solution calculation of the picking arm are made using D-H method. The kinematics simulation function of ADAMS is used for the simulation analysis of the kinematics features of the forestry nut picking arm and the feature curves of displacement, velocity and acceleration of the end effecter of a machine under a specific motion status are obtained, which provides reference evidence for the motion control and the optimal design of picking arms.

After analyzing and comparing, the method in reference (1) is improved. The whole boom, including jibs, is simplified as a combined structure and the rigid jibs and flexible ropes used on boom frame are analyzed and treated. Influences of adopting overlapping principle in force equation on calculation results of last inner forces in rigid jibs and flexible ropes are described.
