The 3-dimentional sold modeling of nut picking arm of nut plucking machine was built up by means of CAD software Pro/Engineer.With the Pro/Engineer,3-D motion simulation for the designed plucking arm was made,and we studied if there existed interference effects among its parts and obtained the motion trajectory and of motion envelope curves.According to the result of simulation and analysis,the structure size of the picking arm was designed and optimized in order to obtained a rational 3-dimentional model of picking arm,provided a tec...
