| Abstract: | Based on MSC.PATRAN simulation platform,three-dimensional finite element model of giant forging presses frame is established in high-hexahedral unit.By finite-element dynamic analysis,the six-order natural frequency and the corresponding modal vibration mode of the frame are obtained.This paper analyzed the transient response of a sudden unloading frame,the distribution of the stress and deformation,providing reference for further study on mechanical properties and dynamic frame design. |
