N2 - Foreign object damage (FOD) is a frequent but dangerous failure of the compressor. Blade tip timing (BTT) is regarded as a promising on-line monitoring method for blades, but it is difficult to obtain the real FOD data in a laboratory environment. This paper proposes a virtual BTT measuremnt method for FOD. Firstly, we establish the dynamic response model of the multi-degree of freedom damped system, and use the modal superposition method to infer its response displacement under the impact of a foreign object. Secondly, we use the Johnson-Cook model to calculate the stress limit of the blade model. Thirdly, finite element analysis is employed to calculate the influence of different impact positions on the blade tip displacement and the blade failure. Finally, we use the Simulink module to simulate the blade vibration displacement signal, and the measurement process according to the principle of tip timing. By this means, the laboratory simulation of BTT measurement under FOD is realized.
