| 中文摘要: |
| 目的 对除气塔液体冷却器进行抗震分析，以确保其在地震下必要的安全功能。方法 以福清5/6号核电工程为背景，通过有限元软件ANSYS建立除气塔液体冷却器有限元模型，采用反应谱法进行设备的抗震分析与评定。结果 通过抗震分析评定，发现设备鞍座为设计薄弱区域，故修改鞍座的结构形式，包括新增筋板、增加壁厚，使该设备的设计满足了相关规范的要求。结论 通过修改鞍座的结构形式，确保其必要的安全功能得以实现，满足实际工程的需要。 |

| Objective To carry out seismic analysis for the degassing tower liquid cooler to ensure necessary safety function under the earthquake. Methods With FuQing 5/6 nuclear power station as an example, the finite element model of the degassing tower liquid cooler was established with software ANSYS, and the response spectrum method was adopted for seismic analysis and evaluation of the equipment. Results Through seismic analysis evaluation, the calculation process and characteristics of spectral analysis was learned and the weak area of equipment was found out. Therefore, the structure of the saddle was modified by increasing rib plate and wall thickness to make the equipment meet requirement of relevant code. Conclusion The structure of the saddle is modified to guarantee its functions and meet the needs of the practical engineering. |
