【摘要】 本研究采用的优化方法是复合形法．在五维非线性约束的设计空间内选择和改进设计点，并通过平面问题的有限元法计算出每个设计点的目标函数值（机身体积）以及校验隐式约束所需要的单元应力和节点位移． 作为实例，本文还着重对Ｊ２３—６．３型开式可倾压力机机身的优化问题进行了分析计算．更多还原

【Abstract】 The "complex-method" is adopted for optimum algorithm of selecting and improving design points in a 5-dimensional nonlinearly contrained design space. The finite element methdoby way of plane stress is used for calculating the volume of the press frame, which is the objective function value, and the element stresses and node displacement. which are required for cheking implicit constraints. As an example, design optimization of the frame of Model J23-6, 3 Open Back Inclinable Press is studied.更多还原
