Embodiment Construction
[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0017] combine figure 1 , the protected marine power equipment 1, the intermediate mass 2, the elastic shock absorber 3 and the elastic shock absorber 4 constitute a double-layer vibration isolation system, which is placed on the hull foundation 5; the vibration pickup sensor 6, the shock pickup sensor 7, The DSP controller 8, the constant current source circuit 9, the DC power supply 10, and the electromagnetic semi-active vibration absorber 11 constitute a semi-active control system. The protected marine power equipment 1 in the double-layer vibration isolation system is equipped with an electromagnetic semi-active vibration absorber 11, and its vibration signal is measured by the vibration pickup sensor 6 as a vibration detection signal, and the shock pickup sensor 7 detects the hull foundation The acceleration signal of 5 is used as the impact judgment signal...
