Accounting for The Effects of Induction Hardening in The Modeling of Automotive Parts 2001-01-0639
This paper describes a method to account for the effects of induction hardening in computer simulation of automotive parts. This method, which is currently being used at PSA Peugeot-Citroën, enables the rapid optimization of shapes and heat treatments (usually for weight reduction purposes). It is a two-stage method. The first stage is based on simple topological geometries accounting for the heat treatment, which are implemented directly in the finite element model Abaqus®. This first stage allows for a succession of quick iterations. The second stage of the method consists of linking the various relevant process simulation softwares (Forge3®, Sysweld®, etc.) and Abaqus®, in order to confirm the optimized shape and treatment obtained in the first stage. Simulation of transmission auto parts will be presented as illustrations of this method.
