“…The frequency at Q =1 is named as ring frequency, which means that the wavelength of the axial wave is equal to the circumferential length of the shell as = 1 . All the coefficients A1 (Q) of the polynomial in equation ( 4) can be expressed in the form of the functions of non-dimensional frequency ) , and the detailed expressions are not given here for brevity.…”

“…The structural discontinuity is also used for control the vibration of coupled vibration wave in cylindrical shell filled with fluid. Xu et al [4] analyzed the vibration wave transmission and reflection at the wall joint in a fluid-filled shells, the transmission loss of vibrational power flow through the wall joint is investigated and an analysis of power flow transmission and reflection at the joint is presented. Parameters of the joint and frequency were found to strongly influence the results.…”

Theoretical analysis of active control of vibration in a cylindrical shell is presented in this paper. The forced vibration wave in a circular cylindrical shell is studied and the propagation of the vibration wave is controlled actively. The structural model considered is an infinite elastic circular cylindrical shell and excited harmonically by a primary force arranged in a line around its circumference. Active control is achieved by applying another line circumferential distributed force apart from the primary force. The input vibration power flow is theoretically studied and used to evaluate the performance of the active control method. Numerical simulation results demonstrate that it is possible to achieve a vibration reduction of 1 5 dB for only one control force. To realize this active control force, smart actuators such as the piezoceramic material can be used. It is hoped that the investigation will shed some light on the control ofvibration propagation in such structures by using smart materials.

Coupled vibration of arterial tubes is analyzed with the wave propagation approach and first-order shear deformation theory. Both the interior and exterior fluids are considered as compressible so that acoustic waves can be generated and propagated in the fluids. Results obtained using the theory have been evaluated against those available in the literature and the agreement has been found to be good. The theory can be used for future research on the vibration and acoustics of arterial walls. Vibration experiments were carried out on a silicone rubber tube in a water tank with a novel ultrasound stimulated optical vibrometry system. This system uses the radiation force of ultrasound to vibrate the tube at low frequency and records the resulting response by a laser vibrometer. Both the excitation and measurement are remote and noncontact. The silicone rubber tube was chosen because it has mechanical properties close to those of arteries. The fundamental frequency is well excited by the radiation force and measured with the laser. The measured fundamental frequency is in good agreement with the present theory.
