摘要船舶动力设备是船舶振动噪声的重要来源，其运行过程中产生的宽带和低频线谱振动对舱室噪声和水下辐射噪声具有重要影响。针对船用动力设备质量大、振动强的特点，提出一种结构紧凑的低频橡胶隔振器与线性电磁作动器复合的主被动隔振器，并分别对被动隔振器的静态承载能力、电磁作动器的驱动力以及主被动隔振效果进行了仿真分析和测试，结果表明橡胶隔振器可承受15吨载荷，具有线性刚度，电磁作动器力常数可达72N/A，与频域加权的干扰重构Fx-LMS控制算法相结合，能大幅抑制300Hz以内的线谱振动，主被动联合隔振效果优异。

Abstract：The broadband and low-frequency tonal vibration generated by power equipment has an important impact on the cabin noise and underwater acoustic radiation of vessels. A passive/active vibration isolator is proposed to support heavy marine power equipment and attenuate vibration transmission. Since it is difficult for the conventional Fx-LMS algorithm to attenuate multiple harmonics of different amplitudes equally in practice, a frequency domain weighting technique is introduced to the adaptive algorithm to improve the frequency response characteristics of the control channel and increase the proportion of weakly controllable harmonic components in error signals. The static bearing capacity of the rubber isolator, the driving force of the actuator and the performance of the passive/active vibration isolation are investigated. The results show that the rubber isolator is of linear stiffness and able to bear 15-ton payload, and the estimated force constant of the actuator is 72N/A. Utilizing the frequency domain weighted Fx-LMS algorithm, the harmonics within 300Hz are greatly suppressed, which demonstrates the effectiveness of the passive/active vibration isolator and the improved adaptive algorithm.

Key words： power equipment vibration isolation passive/active vibration isolator low frequency tonal vibration adaptive algorithm
