It is showed that the limit drawing height could be greatly improved as a variable BHF deep-drawing process was adapted.
结果表明，变压边力拉深工艺能够极大提高板料的极限拉深高度。
The simulated thickness with separation force is smaller than that with blank-holder gap because the BHF is variable in the flange region.
采用分离力时的模拟厚度比压边间隙小是由于法兰区域的变压边力。
