Addressing deformation characteristics of the shell during rotarypiercing operation, wall thickness unevenness is calculated by means of the FE simulation method.
通过有限元模拟针对斜轧穿孔过程中毛管的变形特点,对其壁厚不均进行了计算。

Piercing efficiency is one of the critical parameters concerning deformation under rotarypiercing and there is no existing mathematic model for accurate calculation therefor.
穿孔效率是斜轧穿孔变形中的重要参数之一,至今尚无精确计算的数学模型。
