Chapter 54 An Advanced Structural Analysis Method for Connector Terminal Based on Multi-step Forming

摘要

Based on the history of multi-step stamping, an advanced analysis method is proposed to analyze the structural properties of metal part. This method combines multi-step stamping forming and structure analysis together. The forming of metal blank is simulated to obtain the shape (thickness) variation, spring-back, residual stress and hardening material properties by multi-step stamping using the Abaqus/Explicit software; then the non-uniform thickness stamped part obtained is used to analyze the subsequent structure properties through mapping residual stress and hardening material using the Abaqus/Standard software. The terminal of connector is taken as an example and its normal force is analyzed with the above proposed method to demonstrate its analysis process. The method presented here conduces to improving the precision and ability of structural analysis.
