In order to discuss opening and cavity shear flow-induced vibration and structural coupling resonance,experiments of opening and cavity shear flow-induced vibration and structural noise control are carried out.The impact of the opening size,flow velocity and cavity thickness on shear oscillation noise,self-noise in the cavity and radiated noise are analyzed.The results show that the empirical formula of the opening shear oscillation in air is also applicable to the condition underwater,which the shear oscil...
