| Abstract: | To more accurately manufacture an auto-body workpiece, a predictive compensation factor method was used to predict the workpiece’s
springback, and the factors influencing springback are introduced. Based on this method, a numerical simulation was produced
to simulate the springback compensation after distortion of the workpiece. After analyzing the simulation results, a compensation
method was introduced to reduce the springback influence on an actual workpiece. Here, we used a fortified B-pillar, which
is a kind of longitudinal stand-frame workpiece, made with a high-strength steel material (TRIP700). The simulation results
indicated that the proposed method is feasible and can be efficiently used for predicting the distortion of springback compensation
of an auto-body workpiece. |
