摘要
应用NX-NASTRAN对核级阀进行抗震分析,计算了阀门的固有频率。采用等效静力法计算阀门在承受地震载荷及组合载荷共同作用下的应力及变形,并根据ASME AG1标准作出了应力评定和强度校核。从而验证核级风阀在预定载荷下能满足结构完整性。
Seismic analysis of classified blow valve w as done by NX- NASTRAN. Firstly,natural frequency of valve w as calculated,secondly stress and distortion of valve under seismic load and the combination load w as calculated,thirdly stress evaluation and strength check w ere performed in accordance w ith ASM E AG1。And then it satisfies structural integrity under the specified load combination.
