Power mechanical components such as impellers vibrate more easily under external excitation or self power. To avoid harmful consequences such as fatigue damage and structural damage,it is important to analyze its vibration characteristics deeply. In this paper,the impeller of XA100 /32 single stage centrifugal pump in a dry state is taken as the object of study,organically combining ANSYS Workbench collaborative simulation platform,the Germany BBM vibration test and analysis system and the LMS Test.lab experimental modal analysis software. The first six natural frequencies and vibration modes of the impeller are obtained by simulation and modal analysis respectively. The relative error of the inherent frequency of the two methods is basically less than 10%.
