摘　　要：针对舰船机械设备存在的低频线谱振动,设计了一种电磁作动器与液压悬置结构有效并联的电磁液压主被动复合隔振器。该复合隔振器利用电磁作动器输出力抑制低频线谱振动,液压悬置结构隔离宽频振动且实现了对电磁力的有效放大,具有占用空间小、承载能力大、输出力大等优点。对主被动复合隔振器电磁和液压悬置部分进行了建模分析,提出了考虑通道耦合振动的分布式多通道修正解耦算法,保证了滤波器权系数正确收敛。开展了多线谱激励的多通道主被动隔振控制实验,结果表明该主被动复合隔振器对3根线谱取得平均35.12,39.51和38.35 dB的衰减,控制效果显著。Since low-frequency line-spectrum vibration exists in ship mechanical equipment,an electromagnetic-hydraulic active-passive vibration isolator is designed with an electromagnetic actuator and a hydraulic suspension structure.The composite vibra-tion isolator uses the output force of an electromagnetic actuator to suppress low-frequency line-spectrum vibration.The hydraulic suspension structure isolates broadband vibration and enlarges the electromagnetic force.It has the advantages of small footprint,large carrying capacity,and large output force.The electromagnetic part and hydraulic suspension part of the composite vibration isolator are modeled and analyzed,respectively.A distributed multi-channel modified decoupling algorithm is proposed by consider-ing the channel coupling vibration to ensure the convergence of filter weight coefficients.A multi-channel active-passive vibration isolation control experiment with multi-line spectrum excitation has been carried out.The results show that the active-passive com-posite vibration isolator can achieve an average attenuation of 35.12,39.51 and 38.35 dB on three line spectra,and the control ef-fect is significant.
