Abstract

Based on the ODS, the dynamic characteristic of the fan impeller is obtained using ODS FRF method, and traditional experimental modal method (impact hammer testing) is also done on the same impeller for comparison. The compared results show that the result by the ODS FRF method is more desirable than that by the traditional impact modal method.
