| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 101 === A multi-objective optimization design process for a toggle mechanism used in a automatic die-cutting machine is presented. For analyzing the kinematic and dynamic characteristics of this device, the mathematical model is first established. To reduce the dynamic reactions caused by the high working speed and load in operation, the dimensions of links of the toggle mechanism are considered. To optimize the links of the linkage, the Augmented Lagrange Multiple Method with Simplex Method is used. To demonstrate the multi-objective optimization design process, a practical case with a die weight of 1230kg of, a cutting force of 3.92MN, and a working speed of 150rpm is synthesized and analyzed. In addition, the optimized results obtained for the toggle mechanism with and without counterweight are investigated.
