摘要
Under harmonic excitation, nonlinear vibration isolation system exhibits chaotic response in a certain parameter range. When this system is used to eliminate the periodic component in the water-borne noise, the concealment capability. of warship can be improved. In order to design a practical chaotic vibration isolation system, this special parameter range of the system should be studied. At present, there are two methods available to determine this range, including experiment and numerical algorithm. This paper presents the numerical algorithm to determine the chaotic parameter range, and the variation of the parameter range when the magnitude of the excitation force is proportion to the square of the frequency.
