汽轮机高强度螺栓设计方法探讨

Discussion of High-Strength Bolt Design Method in Steam Turbine

通过比较国内外高强度螺栓设计计算方法的异同 ,指出了传统螺栓计算方法在确定螺栓预紧力、螺栓应力分类以及确定螺栓载荷等方面存在的不足 ,并试图给出一个适合我国螺栓材料的螺栓设计方法供设计人员计算。

By comparing the differences of bolt design methods both at home and abroad,the article states the limitation of traditional high-strength bolt design method in the areas of determining the bolt pre-stress,classifying the bolt stresses and determining the bolt forces,and hopes to give a new bolt design method which can be used as calculation and verification to designers.
