| 摘 要： | 通过建立宜兴抽水蓄能电站地下厂房三维有限元模型对厂房整体结构进行了模态分析和共振复核,采用谐响应动力分析法及时间历程响应分析法分别计算了厂房结构在各种机组动荷载作用下的振动响应及从正常运行工况向飞逸工况过渡过程中的振动响应,并根据国内外有关规程提出了振动评价标准.研究结果表明,厂房结构共振的可能性较小,振动响应均在允许范围内.

| Abstract: | The mode analysis and the possibility of resonance in the underground powerhouse structure of Yixing Pumped Storage Station were studied by establishing three-dimensional finite element model.The harmonic and transient analysis methods were proposed to study the vibration response of the powerhouse structure under various generating unit dynamic loads and in transient process.The numerical results were evaluated according to the related rules and regulations both in China and abroad.The result shows that th... |
