Study on the Forming Process Parameters of Automobile Front Panel Reinforcing Plate Using Orthogonal Experiment Method by Numerical Simulation Technology

Abstract

A methodology to design optimal forming process and relative parameters of the automobile front panel reinforcing plate, using the numerical simulation technology of forming sheet metal, is investigated. The digital model of the complex automobile part is established by computer aided design software. Dynaform software is used to simulate its forming process to acquire the feasible process parameters affecting its formability. Forming limit diagram and thickness distribution diagram are used to evaluate the simulation results of different process schemes. The orthogonal experiment method is adopted to design and simulate the process parameters to find out the optimum values for die design. The reasonable process design and optimum values of fillet radius of female die, friction coefficient and blank-holder force are obtained, which can reduce the tendencies of wrinkling, crackling and thickness reduction, and achieve sufficient plastic deformation of blank.
