楼板孔上的"防水肩"如何翻译? hole-flanging 1.圆孔翻边 research on hole-flanging limit and distortion with tc1mδ2.5 titanium alloy sheets tc1mδ2.5钛板圆孔翻边成形极限与翘曲的研究 2.翻孔 the forming mechanism of hole flanging on a thick-wall heavy cylinder forging is simulated by deform3d, and it is 4390mm in length and 390mm in thickness. 采用deform3d[wiki]软件[/wiki]对径向尺寸和壁厚分别为4390mm和390mm的大型厚壁筒体翻孔工艺进行了模拟研究。 网上查了下,貌似和楼板孔上的"防水肩"毫无关系,期待答案。查看更多
