As a basis for developing experimental identification techniques for boundary conditions of a linear vibratory system, a technique for a beam is proposed. The proposed technique enables one to determine, using data of dynamic responses of a beam, the boundary conditions in terms of spring constants, damping coefficients, and equivalent masses and moments of inertia. Numerical simulation is conducted, and the applicability of the proposed technique is show.
