Structure optimization research of forging box of 10 MN precision hydraulic forging machine

运用FEM解析对10 MN四锤头液压精锻机的主要零部件锻造箱进行结构强度有限元分析,并以减小锻造箱处应力为目标对锻造箱进行结构优化设计。以锻造箱各尺寸参数作为优化设计变量,以断裂处单元应力最小为优化目标,编制锻造箱优化设计程序ODPST,对锻造箱进行结构的优化。通过优化使锻造箱危险点应力减小约15.5%,锻造箱的强度提高效果明显,延长了其使用寿命。

The structure strength finite element analysis of the forging box of 10 MN four hammer precision hydraulic forging machine was carried out by using ANSYS software,optimal structure design for the forging box was carried out by taking the stress at the forging box as the object.By taking the various dimension parameters as optima design variables and taking minimization of the unit stress at fracture as the target,the optimum structure design program（ODPST） for the forging box was made to carry out optimization of its structure.Through the optimization of forging box structure,maximum stress at fracture is reduced by 15.5%.The improvement effect of the forging box strength is obvious, prolonging its life operation.
