摘要
针对舰船减振降噪问题,提出了一种由电磁作动器和空气弹簧集成的电磁-空气弹簧混合隔振器,对电磁作动器和空气弹簧进行了参数设计,利用Workbench分析了电磁作动器的作动力,并用ABAQUS分析了空气弹簧承载力;建立了隔振系统控制模型,采用LQR最优控制仿真分析其力传递率,表明电磁作动器有效抑制了空气弹簧的低频共振,空气弹簧有效隔离了高频振动,该混合隔振器融合了两者的优点,并避免了各自的不足。
Aiming at vessels＆#39;vibration isolation, a novel electro-magneto-pneumatic vibration isolator （ EMPVI） consis-ting of an electromagnetic actuator and a pneumatic spring was proposed.The electromagnetic actuator and the pneumatic spring were designed.Workbench was applied to analysis active force of the electromagnetic actuator, and ABAQUS was used to calcu-late the pneumatic spring＆#39;s bearing capacity.The control model of the vibration isolation system was built.The force transmissibil-ity was simulated with LQR optimal control theory.The results show that the electromagnetic actuator effectively suppressed reso-nance of the pneumatic spring in low frequency, and the pneumatic spring isolated well in high frequency vibration.The EMPVI was demonstrated to combine the advantages of the electromagnetic actuator and the pneumatic spring with avoiding their short-comings.
