| Abstract: | To solve the performance of the MP1040B moulding machines,optimization design of elbow-bar mechanism of moulding machines was investigated by utilizing the method of exterior penalty function and variational scale of BFGS for unconstraint problems.The result shows that the maximal gradient of lower moulding plank in one motion period declines by 25.6% after optimization,and the angular acceleration of the bottom moulding plank decreases by 21%.Clearly,it can be seen that kinetics performance of the elbow-ba... |
