Abstract
Vibration intensity measurement using a three channel method is proposed as a means for the identification of the impact sources in a machine structure. The envelope intensity technique is also employed to catch the transient feature of the intensity vectors. The application limits of the three channel method and the intensity pick-up are discussed. Vibration intensity measurement is applied to an engine structure in order to clarify the direction of the vibration energy flow caused by combust ion impact.
