Finite Element Simulation on Thermal Mechanical Expansion of the Automobile Rear Axle Housing

摘要

Mechanical thermal expansion is a new metal processing method,which improved not only the properties of materials and the production efficiency,but also achieves better processing surface quality and comprehensive mechanical properties.Axle housing mechanical thermal expansion is simulated by DEFORM-3D,then by metal flow analysis,explored the deformation characteristics through stress-strain distribution and velocity,predicted possible forming defects types and locations and propose appropriate solutions.Through analysis of the influence of different process parameters on the axle housing mechanical thermal expansion,theoretical guidance for actual production is provided.
