【摘要】 利用美国大型通用有限元软件ANSYS模拟缠绕拉拔式弯管工艺过程。通过模拟,计算管子弯曲变形所需的弯矩,计算管子弯曲部分外壁减薄率和椭圆度。利用ANSYS的参数化设计语言,使所做的分析适用于不同的管子直径、材料、弯曲半径。更多还原

【Abstract】 The general-purpose FEM software is used to simulate the manufacturing process of the twisting-drawing pipe bending.The needed pipe bending moment、wall thickness reduction and ovality of section are known by simulating.Using ANSYS parametric design language,this analyzing model can fit different pipe diameter、material and bending radius.更多还原
