摘要: An application of composite elements in machinery design became very popular due to the unique properties these materials. Therefore, it is obvious develop appropriate methods for their diagnostics and monitoring. One group methods, intensively developed last decades, analysis vibration data structures using wavelet transform. The method proposed this paper based on normal modes damaged order detect identify singularities signal, which conclusion about damage presence location could be made. fractional B-spline wavelets during transform signal improves sensitivity allows tuning-up an applied achieving most adequate result investigated problem.
