Paper Title:
Numerical Study of Springback Laws in Metal Forming of Diaphragm of Automotive Horn
  Abstract

The influences of four parameters such as young’s modulus, yield ratio, punch radius and blank thickness on the springback of diaphragm of automotive horn are analyzed by combining experiment with FEM (finite element method), and the springback laws of the parameters’ interaction are revealed. The results show that the springback of diaphragm is influenced by the yield ratio of material evidently, but is influenced by punch radius slightly when the parameters interact. However, the influence of punch radius increases greatly when the young’s modulus is very low. Therefore, the influence of the parameters’ interaction must be considered so as to control the springback effectively when the forming scheme of diaphragm is designed.
