摘要
结合中型注塑机对双曲肘合模系统优化设计进行了研究,指出中型机以功效系数最大建立的优化数模属非凸函数,非凸集,具有多解性。所取得的满意解明显优于现行设计。文中还讨论了设计变量与目标函数间的关系,并进行设计变量的灵敏度分析,为实际工程设计的方案选择、公差合理制定提供了依据。
Study of the optimum design of the double arm link clamping system has been made based on a middle sized plastic injection machine, it is pointed out that for middle sized machines, the feasible regions bounded by constraints are nonconvex sets and the objective function with the highest efficiency coefficient is nonconvex function as well, which has more solutions, the satisfied solution in the paper is far better than the realistic design. This study provides the reasons for the choice of configurations and reasonable decision of tolerance in the design of plastic injection machines.
