Optimal mass ratio of vibratory flap for vibration control of clamped rectangular plate

Determination of the workflow of energy-saving vibration unit with polyphase spectrum of vibrations

“…There is no justification why the effect of friction in the contact between the working body and the environment is insignificant. In [12], a study is conducted to determine the optimal mass ratio of the vibration valve for control vibration and the mass clamped by a rectangular plate. The problem of a dynamic vibration damper in discrete systems, known from the theory of vibrations, is applied.…”

Experimental Study on Effect of Vibratory Flap Position on Dynamic Response of Clamped Rectangular Plate with Cut-Out

“…The position of the flap is symmetrical with respect to centre line along the length of the plate. The flap is fixed as a cantilever plate at a tilt angle of 45° at different locations on the plate with fixed edge of the flap perpendicular to length of the plate [7,8]. The schematic drawing of the plate with observation points and flap locations are shown Fig.…”

“…Ulz and Semercigil [6] introduced the use of cut-out to improve the performance of the plate by creating the flaps as incisions. The present authors investigated the effect of position and tilt angle of the auxiliary flap on vibration control of rectangular plate by the finite element analysis [7] and by experiments [8] and have shown that the optimum tilt angle is 45°.The authors also have investigated the use of flap to locate cut-out in plate by finite element analysis [9].…”
