该方法给出了基于面积值判断的快速终止条件，避免了异常情形的特殊处理，并能通过区域测试快速判定两多边形是否发生干涉。
QQH algorithm provides a fast terminate condition based on judging the area and avoids the special process for the exception, as well as determines whether interference occurs or not by region test.
应用动力显式数值模拟软件，研究了线性渐增和渐减变压边力下拼焊板盒形件的成形过程。建立了线性变压边力终止值随初始值变化的关系曲线，该曲线被拟合为二阶多项式曲线。
The forming of box with TWBs based on a series of linearly increasing and decreasing variable blank holding forces(VBHF)over the stroke were studied by means of dynamic explicit finite element method.
