| Abstract: | In this paper,measurement and analysis of the casing vibration model for sometype engine at its critical rotation speed is preserted. Meanwhile, the theoretical analysis of the dynamic characteristis for the engine casing has been made. The measurement and analysis and theoretical computation show that measuring casing vibration model by use of strain gauge is a ethetive measurement method and the theoretical basis for monitoring engine condition and revising structure is provided. |
