摘要
采用有限元方法模拟了1台含缺陷冷凝器的应力状况,并进行了静强度分析。针对焊接缺陷,采用断裂力学方法分析了该含缺陷结构的安全性。利用模糊分析方法讨论了冷凝器的使用风险。结果认为,该冷凝器满足安定性理论且合乎使用原则,在使用过程中用户应承担严重的风险。
The stress situation, the static strength, the fracture strength and in-service risk for a condenser with welding defects were discussed. Upon these analysis, it reaches the conclusion that the condenser has the “serious” risk , although the condenser is satisfied with the shakedown theory and fitness for purpose theory.
