Abstract EN
This paper addresses the vibration and sound radiation of a nonlinear duct.
Many related works assume that the boundaries are linearly vibrating (i.e., their vibration amplitudes are small), or that the duct panels are rigid, and their vibrations can thus be neglected.
A classic method combined with Vieta’s substitution technique is adopted to develop an analytic formula for computing the nonlinear structural and acoustic responses.
The development of the analytic formula is based on the classical nonlinear thin plate theory and the three-dimensional wave equation.
The main advantage of the analytic formula is that no nonlinear equation solver is required during the solution procedure.
The results obtained from the proposed classic method show reasonable agreement with those from the total harmonic balance method.
The effects of excitation magnitude, panel length, damping, and number of flexible panels on the sound and vibration responses are investigated.
