Abstract：

Modal analysis of the lower composite beam of 165MN large free forging hydraulic press machine was presented through finite element analysis software-Marc.The fore ten natural frequencies and corresponding vibration modes of the lower beam of forging hydraulic press machine were obtained.The results show that the natural frequency f2=61.3Hz and f7=127.1Hz of second order and seventh order modal should be avoided.The method has a important reference value in understanding the dynamic behavior characteristics of the lower beam of forging hydraulic press machine and structural optimization designing.
