- Abstract
A calculation-experimental method is presented for determining the contribution of individual mechanisms to the vibrational and acoustic field of complex structures. The method is based on measuring vibrations in a set of points on the vibration energy propagation path from an operating mechanism, as well as on the subsequent calculation of the dynamic forces and external field using a numerical model of the structure. Experimental implementation of the method has shown that the contribution of an individual mechanism can be evaluated with high accuracy, including in the presence of vibrations at its base induced by external sources, the magnitude of which may significantly exceed the eigenvibrations of the mechanism.
