试验中还观察到在拉伸断口应力方向的断面上出现了熔化现象,这说明在拉伸断裂区局部存在着剪切现象,同时证明采用高能束改性后圆筒在爆炸载荷作用下可产生全壁厚剪切断裂。
A macro and micro and chemical element analysis was made on fracture of ruptured coupling bolts,torsion test was performed and stress analysis and calculation were made,the results show that when the steam turbine had failure,MP-LP rotor coupling bolts and generator-exciter rotor coupling bolts failure were classified as overload shear fracture with partial deformation .
对215MW汽轮机断裂的对轮螺栓做断口宏观、微观分析,化学元素分析,扭转试验及受力分析计算,结果表明汽轮机组在事故中,中压-低压转子对轮螺栓和发电机-励磁机转子对轮螺柱的失效类型为:过载剪切断裂,同时局部挤压变形,这是由于事故过程中轴系受到冲击扭矩作用而引起的。
