Abstract
The vibration equation of a stiffened plate is derived and the solutions are obtained by using the Laplace transformation. Input and transmission vibrational power flows of the plate are studied theoretically and experimentally. The studies indicate that Non-Obstructive Particle Damping (NOPD) can restrain the peak values of power flow and its propagation. The effects of different NOPD on the vibrational power flow of structure are discussed. The conclusions provide a theoretical basis for structural optimal design and damping optimal allocation. The method of reducing noise and vibration with NOPD can give some guidelines for engineering.
