【摘要】 利用ANSYS软件对筒形件3旋轮缩径旋压过程进行了三维有限元数值模拟, 获得了应力、应变的分布情况, 并对缩径旋压时起旋点附近的局部变薄及口部扩径现象进行了分析。模拟结果与实际旋压过程相一致。更多还原

【Abstract】 The spinning process of three roller neck spinning of tubes is simulated by the 3D ANSYS softwareThe distributions of stress and strain are obtained, and the local thinning at the starting point of spinning and the diameter expanding at the opening are analyzedThe simulation corresponds well with the practical spinning更多还原
