- Abstract
method suggested earlier for searching for sources of vibroactivity and maintenance defects in complex mechanical structures has been experimentally implemented. The method is based on joint use of a numerical finite-element design model and coherent vibration measurement at several control points. The search for defects is implemented by analysis of vibration field measurements at a control point related to scattering on the arising defect. Results are given from a study of the method's efficiency depending on the number of control points for measuring vibrations and the type of the source's spectrum.
