【Abstract】 Tailor-welded blank(TWB),which is welded with the same material and different thickness or different material and the same thickness or different material and different thickness,has abroad applications in automobile industry.Deep drawing of square box part of tailor-welded blank(TWB) were studied by experiment and simulation.The movement of the weld-line was acquired.The weld-line moves toward the thick part on the bottom of the square boxes and toward the thin part on the wall of the square boxes.The effects of blank holder force and drawing ribs to the movement distance of the weld-line were analyzed.更多还原
