dcterms:abstract
  • In this paper, finite element analysis of an automatic five stage precision cold forging process of a yoke, a steering part of a passenger’s car, is conducted with emphasis on spring back analysis at the yoke forming stage and its experimental verification is subsequently made. An elastoplastic finite element method with MINI element technique employed for the analysis of the entire process is explained. There is emphasis that the thin film of material formed between the punch and die in the stage may result to some errors especially in elastoplastic finite ele ment analysis of spring back due to frequent remeshing. The numerical robustness of the spring back analysis in regards to remeshing is hence shown first through investigation into its effect on the predicted spring back. Experimental measurement of displa cement due to spring back is carried out for comparison with the predicted results, and they are in a qualitative agreement with each other (xsd:string)
