An experimental identification technique for joint properties of structures and machines is considered. The technique uses transfer functions of the objects before they are assembled. The technique requires neither application of the excitation on nor measurement at the joints. The technique can identify the joints with nonlinearity. The main procedures of the technique are: (a) to model the joints by springs and dampers as well as equivalent masses and moments of inertia, (b) to apply the periodic excitation and to measure steady state responses of the objects in the assembled state, and (c) to determine the joints properties by use of the transfer functions and by applying the principle of harmonic balance. Numerical simulation is conducted, and applicability of the technique is confirmed.
