头翻 meaning in Chinese

head dip
head kip
somersault on the hand

Through using abaqus software , a numerical simulation of equivalent stress field of flanging deformation process with cone - shaped punch was carried out , and compared with simulation of flanging deformation with column - shaped punch
摘要利用abaqus商用软件，对锥形冲头翻边变形过程的等效应力场进行了数值仿真，并与柱形冲头的翻边变形仿真进行了对比。
General rules were validated and a new rule was discovered : i . e . the shape 0f these two stress fields are same , the equivalent stress of the round corner in the bottom reached its maximum at the first phase , the equivalent stress of the edge of hole reached its maximum at the third phase , the equivalent stress of flanging with cone - shaped punch descend more than that with column - shaped punch at the fourth phase i . e . the phase of deformation completed
验证了一般规律，也发现了新规律，即两者的应力场形状相同，底部圆角处等效应力在变形第1阶段最大，孔口边缘处等效应力最大出现在变形第3阶段，第4阶段（变形终了时）锥形冲头翻边的等效应力比柱形冲头翻边时下降更大。
