开式压力机刚度多目标优化设计

Multiple-Obiect Optimum Design on the Rigidity of Open-Back Inclinable Press

本文采用 Powell 直接搜索法和序列无约束极小化技术(SUMT),对开式压力机的刚度进行了多目标优化设计,所得结果表明,采用本文介绍的优化方法对提高开式压力机的精度效果明显。

This paper adopts Powell′s direct search method and sequential unconstrained minimization technique(SUMT) in the multiple-object optimum rigidity of open-back inclinable press.The re- sult obtained shows that the optimum method introduced in this paper has an obvious effect on the increasing of accuracy of open-back inclinable press.
