Structure Dynamic Characteristics Improvement Design of Pump Impeller |
| |
| Abstract: | Impeller is one of the key components of submarine stirring impeller. Its dynamic characteristics have a great impact on the later key characteristics,such as dynamics,vibration and noise,economics,etc. The paper brings focus on the study of a kind of impeller's dynamic characteristics 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 paper proposes a method of improvement design of submarine impeller basing on dynamic characteristics optimization. |
