采用大型通用有限元分析软件ANSYS对缠绕式弯管制造工艺进行数值模拟分析 ,计算出弯管在弯制成形后的外壁减薄率和内壁增厚率、弯管的应力应变分布等相关工艺参数 ,并比较了不同的相对弯曲半径对壁厚减薄的影响
A large general finite element analysis software ANSYS was used to simulate the manufacturing process of the winding elbow, and the related process parameters such as the wall thinning rate, the wall thickening rate and the stress-strain distribution of the elbow pipe after bending were calculated The effects of different relative bending radii on wall thickness reduction were compared
