核电站用轴流风机是核电厂工程重要设施。因此,必须在设计过程中考虑轴流风机在地震作用下的工作性能,从而保证轴流风机在各载荷工况下的完整性与安全性。通过对轴流风机有限元模型的计算和谱分析验证轴流风机在各工况下的抗震安全性,能满足我国核电设施的相关规范要求。
Axial fan for nuclear power plant is an important facility of nuclear power plant engineering. Therefore, it is necessary to consider the working performance of the axial fan under earthquake action in the design process so as to ensure the integrity and safety of the axial fan under various load conditions. Through the calculation and spectrum analysis of the finite element model of the axial fan, the anti-seismic safety of the axial fan under various conditions can be verified and the relevant specifications of nuclear power facilities in our country can be met.
