|
The conception,theory and significance of finite element model analysis were studied.Taking 300 MN hydraulic die-forging press as the investigating object,the frame's model factors were analyzed based on MSC.Nastran finite element analysis software.Then the frame's original frequencies and model vibration modes were got for the former six steps,which were evaluated in detail by the working practice.According to these results,the stiffness distribution of the frame and the weakness points were gained.From the view of the man-machine engineering aspect,the influence of original frequencies on the people and environment was disscussed.
