Abstract

Steadied forced vibrations of a linear stationary mechanical system are considered. Requirements at which fulfilment, interaction interference of oscillations with the contiguous natural frequencies can be neglected are determined and the system in a environ of a resonance can be considered as a system with one degree of freedom. The problem is decided in the supposition, that elements of a damping matrix are proportional to elements of quasielastic coefficients matrix are or elements of a inertia matrix. Operation is carried out at a support of the Russian Fundamental Researches Fund (the design No 06-08-01005).
