The method is in fact that one excites forced fibrations of mechanical object fixed in table of vibro-=exciter in frequency range of resonance range at constant level of vibro-displacements of table, one registers signals x, y proportional to vibro-displacements of table of vibro-exciter and mechanical object, respectively, with determination of damping coefficient. One determines signal 2 proportional to respective vibro-displacement of table of vibro-exciter through determination of difference of signals x and y, with registration of maximum of signal 2 with respect to vibro-displacement, at that one determines value s of phase shift on frequiency at which signal 2 is maximal and damping coefficient is found from relation
