【Abstract】 A method of three-degree-of-freedom tandem mechanics optimization based on trajectory is proposed. The rigid body dynamics model is established under the trajectory and motion state of the known manipulator. The optimization of the manipulator is carried out with the minimum of the joint moments and the maximum value of the joint, and the optimized manipulator is compared with the original machine. The engineering example shows that the maximum value of the joint torque and the optimization of the optimized manipulator is about 10.8512%, and the dynamic effect is improved obviously.更多还原
