摘　　要：分析了某压机框架的结构特点,在合理简化的基础上,建立了有限元分析模型。对其进行了结构分析,获得了应力和应变的分布情况。分析表明,压机框架强度较弱的位置位于立柱和圆角处,强度和刚度满足要求。同时对有限元分析结果进行了试验验证,结果表明:分析值与测量值变化趋势一致,数据基本吻合,从而验证了压机框架强度和刚度分析正确,有限元建模方法合理。After analyzing the structure characteristics of cer- tain press frame, the finite element model of press frame was builtthrough the reasonable simplification. The stress and strain distribu- tion condition was obtained by carrying out structural analysis. The analysis results indicate that the location where the strength of the frame is much weaker is at the filleted comer and the column while the strength and rigidity can meet the requirements. Meanwhile, the experimental verification on FEA results was carried out, indi- cating that the change tendency of analyzed values and measuredvalues is same, which are matched basically. In this way, it has been proven that the strength and rigidity analysis of the frame is correct and the finite element modeling method is reasonable.
