Embodiment Construction

[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0017] 1, the protected marine power equipment 1, intermediate mass 2, elastic shock absorber 3 and 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 A sensor 7, a DSP controller 8, a constant current source circuit 9, a DC power supply 10, and an 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, and the two signals are input in...

Abstract

The invention is concerned with the vibration reduction anti-impinge half-initiative controlling device based on the electromagnetism bump leveler, includes: the half-initiative bump leveler and vibration pick-up sensor setting on the protected power equipment, the impinge pike-up sensor setting on the hull basement, the vibration pick-up sensor and the vibration pick-up sensor connects with the DSP controller respectively, the DSP controller connects with the half-initiative passing the constant current source circuit, the constant current source circuit connects with the direct current power supply. The invention can satisfy the need of impulsion control, and improve the capability of the double-layer vibration isolation system.

Description

(1) Technical field [0001] The invention relates to a vibration reduction and anti-shock device, in particular to a vibration reduction and anti-shock device for propulsion power equipment or devices on board a ship. (2) Background technology [0002] The working environment of marine power equipment is that shock and vibration exist at the same time. In recent years, with the development of modern weapon technology, the explosion equivalent and impact duration of underwater explosions have increased significantly, and the hit rate has also increased. The threat to marine equipment is also more serious. Improve the impact resistance of marine power equipment It has become an urgent need to ensure the vitality of modern ships. [0003] At present, there are no literature records at home and abroad on the research on the anti-shock active control system of marine power equipment. (3) Contents of the invention [0004] The object of the present invention is to provide a sem...
