Abstract

Abstract

In this paper, the seismic analysis and seismic test of a nuclear vortex process fan are carried out. Based on the test, the seismic analysis method of this kind of fan is obtained. Firstly, the finite element model of the fan is established, and the main modal frequencies of the fan are obtained through modal analysis, which are compared with the dynamic characteristic detection test results; Then, the strain of the fan is analyzed and calculated by the response spectrum method, and compared with the strain results measured in the seismic test. The results show that the seismic analysis method used in this paper is reasonable and can obtain accurate seismic response results, so it can be considered as an alternative to the seismic test of this kind of fan.
