Study on numerical simulation of automobile covering parts stamping forming process

摘要：

Fine blanking is a kind of advanced metal forming technology which is widely used in automobile industry. Perform the 3-D numerical modeling of the automobile covering parts by the Pro/E software, create both addendum and blank holding surfaces, and import them into the DYNAFORM so that a FEM model can be created. Use the DYNAFORM to perform the simulation calculation and analysis, and study the influences of the factors such as friction coefficient, die clearance and material parameters (n and r values) on the stamping formability. The results show that the parameters such as friction coefficient between die and blank, die clearance and the v value in the material parameters play the key role in the the blank flowability, and have the significant influence on the stamping result.
