Design Analysis and Field Try-out of Automotive Panel Dies
자동차 패널금형의 설계해석과 현장 트라이아웃
Abstract
This study suggested the practical method which can reduce the lead time of the field trial and design of the dies. The virtual manufacturing, with the die design is evaluated by computer analysis, reveals the impropriety of a design before making dies. Three methods for reducing the die making process occupying over 60% of the automotive development are like fellows : First, the crack virtually adjusting the blank holding force and draw bead force with a computer simulation. Second, the parts which can not remove the forming defects in spite of the adjustment of forming process parameters need to modify the part geometry or punch temporary shape. Third, the simulation before trial, field trial, and field trial simulation can be used effectively in the die design.
