| Abstract: | In order to eliminate line spectra in the radiated noise from marine ships,chaos method was applied in vibration isolation.The method improves the ability in isolating the line spectra making use of the particularity of the nonlinear vibration isolation system in chaos.The principle of the chaos method in vibration isolation was presented and performance indices of chaotic vibration isolation system were also given.The method is experimentally verified. |
