M. Beshara et Aj. Keane, VIBRATIONAL-ENERGY FLOWS BETWEEN PLATES WITH COMPLIANT AND DISSIPATIVE COUPLINGS, Journal of sound and vibration, 213(3), 1998, pp. 511-535
In this work, the transmission of energy through a compliant and dissi
pative joint between two thin rectangular plates is investigated using
a receptance approach. Exact formulae for the spectral density of the
energy flow through the joint, the energy dissipated at the joint, th
e power input by the external excitation and the vibrational energies
of the two plates are established when the plates are subject to rando
m ergodic forcing. The more general case of a row of plates which are
simply supported along the two longitudinal edges and coupled through
compliant and dissipative joints is also investigated. The aim of this
study is to examine the effect of joint damping and compliance on the
magnitudes of energy flows through the joints and energy levels of th
e plates. Interest is focused on the energy dissipation at the joints
and the conditions for which it is maximised. (C) 1998 Academic Press
