rotation of flange

Stress concentration often happened along the junction of some axial-flow hydraulic turbine blade and flange of pivot. The spindle blade of a spinning machine is characterized by high rotation speed and good wearability at ire pivot end.

轴流式水轮机转轮叶片进出口边与枢轴法兰连接的根部易出现应力集中。锭杆是纺机中一种数量大、转速高、尖端要求耐磨的杆状零件。

The results show that the welded joint can rotate largely in fire and flexure of column flange and shear deformation are main factors causing the rotation of joint, furthermore, column stiffeners can increase the critical temperature of joint by about 50 ℃.

试验表明：焊接节点在火灾下有较大的转动能力，柱翼缘的弯曲变形和腹板的剪切变形是引起节点转动的主要因素，柱腹板加劲肋可提高节点临界温度50℃左右。

The spiral winding gasket flange angle increased while the MMC gasket flange angle deceased, indicating that MMC gasket inner and outside ring limited the rotation of flange.

缠绕垫法兰受外载后转角增大，而MMC垫片的转角减小，说明MMC垫片的内外环起到了限制法兰转动的作用。
