| Abstract: | Impeller is one of the key components of submarine stirring impeller. Its dynamic character-istics have a great impact on the later, key characteristics: dynamics, vibration and noise,economics, etc. the paper brings focus on the study of a kind of impeller, dynamic charac-teristics with the combination of experimental modal testing theory and finite element theory.After having the conclusion of the two methods having a consistent relationship, the paperproposes a method of improvement design of submarine impeller basing on dynamic char-acteristics optimization.. |
