Vibration techniques become most useful for diagnostic and monitoring of operating turbomachine technical condition. One of the actual areas of diagnostics and monitoring to be developed is the detection of foreign objects entering the intake duct of running engines. When foreign objects impact the surfaces of the engine, this is reflected in its modal properties changing. Modeling the response to foreign objects entering into the inlet of a running engine, the modal properties of its casing parts have to be known. The paper presents FE modeling and the experimental study of the sensor network application to determine the modal properties of turbomachine casings. The study of modal properties was carried out using the technique of Operational Modal Analysis. A comparative analysis of simulated and experimentally determined modal parameters was performed. The conclusion was made about the possibility of using piezoelectric films as sensors for studying the modal properties of engine body parts in a wide frequency range. Analysis of the test results showed a high order of vibration modes due to the complex configuration of the housing parts. © 2024 Latvia University of Life Sciences and Technologies.
