Abstract

Calculating the trimming line is an important step for the panel flanging. In this paper, we use the one step inverse finite element method to calculate the trimming line for auto panels flanging, the finite element model of flanging forming is established and completed the iterative solution of the equation, using the reverse deformation method to establish the linear elastic balance equation to solve the iterative initial value, and thus get the trimming line accurately and rapidly. Through the calculation of the trimming line of some flange part verified the effectiveness of the algorithm.
