多点响应谱抗震分析在核电设备中的应用

Application of Multi-Point Response Spectrum Method in Seismic Analysis of Nuclear Power Equipment

介绍单点响应谱法和多点响应谱法的求解原理,并以新燃料升降机为例,应用ANSYS软件,采用多点响应谱法进行抗震分析,并与单点响应谱法的抗震分析结果进行对比。结果表明,单点响应谱法的计算结果偏大,而多点响应谱法的计算结果更加合理,为这种类型的核电设备的抗震分析提供了一定的参考。

This paper provides a brief theory description of the single-point response spectrum method and the multi-point response spectrum method, respectively. Taking the new nuclear fuel elevator as an example, the seismic analysis is carried out by the two methods with the software of ANSYS. The results of the calculation are contrasted. It shows that the result obtained by the single point response spectrum method is too large and that obtained by the multi-point response spectrum method is more reasonable. And some reference can be provided for the seismic analysis of this type of nuclear power equipment.
