FEM Analysis on the Press Frame Design Based on ANSYS
ANSYS FEM software was applied to static analysis and model analysis of the press machine frame with two design plans.With static analysis, the stress and the displacement of the machine frame were obtained，and with model analysis，natural frequencies and mode shapes of the main frame were presented. It is indicated that the second design plan can reduce the material of machine frame and the production cost under the condition of guaranteeing the constant intensity of the machine frame. And the weight of the machine frame decreases by 22.6%，which achieves a great economic benefit.
