Finite Element Analysis of Cold Extrusion Combination Mold Interference Fit


Article Preview

Aiming at the shortage of tradition design method of cold extrusion stress, and according to the basic equation of elasticity mechanics, the stress distribution at dynamic and static state interference fit of the interlining and outerlining of combination mold extrusion tube is analyzed by using ANSYS software .The result shows: The most fit stress is concentrated on the inner surface of interlining and the contacting surface with the value 1350 MPa, which does not exceed the material allowable stress.This method can fastly and accurately find the most stress of interference fit, which provides more convenience and accurate numerical computes method for design and optimization.
