Marine equipment double-layer vibration isolation device and design method

The marine equipment double-layer vibration isolation device comprises a plurality of independent double-layer vibration isolation units, the multiple double-layer vibration isolation units are installed at the corresponding positions of equipment according to the equipment vibration isolation design requirement, and each double-layer vibration isolation unit comprises an upper vibration isolator, a lower vibration isolator and a middle mass block; according to the double-layer vibration isolator, traditional overall frame type double-layer vibration isolation is replaced, so that the weight is reduced, the space is saved, machining is convenient, and universality is ensured. 本发明提出一种船用设备双层隔振装置及设计方法，包括多个单独的双层隔振单元，多个双层隔振单元根据设备隔振设计要求安装于设备的相对应位置，双层隔振单元包括上隔振器、下隔振器和中间质量块，上隔振器和下隔振器对称设于中间质量块的上下两端，本发明代替传统的整体框架式双层隔振，以减小重量、节约空间，且便于加工，确保通用性。
