Preferably, described surely swing installs additional mass on plate, surely swings the intralamellar part cavity number of plies, closing areola and opening
The arrangement of cavity is configured according to actual needs, improves energy dissipation efficiency；
The working principle that the present invention surely swings plate is that this surely swings plate under the load actions such as wind or wave, by surely swinging strip
Dynamic ambient water movement can produce surface viscous damping, the damping of edge corner cut, the energy dissipation of outside swirl generation, damping
The damping of grain impeller rotation generation, internal particle move energy conversion consumption, particle and the boundary that the electromagnetic induction to be formed generates
The various ways such as the energy dissipation generated are collided to convert simultaneously dissipative structure kinetic energy.Damper uses hollow type cavity structure, and
Increase damping particles rotary blade, it is appropriate to drain, enhance the interaction of platform and water flow, reduces water flow and pushed away to integrally-built
The phenomenon that movement is used, and initial concussion unstability is effectively reduced, so that platform is more stable.
Compared with prior art, beneficial effects of the present invention are as follows:
1) it in the present invention, by combining particle impeller rotation energy consumption and fixed damping particles chamber energy consumption, organically combines
Swaying control and heaving control technology, the vibration problem of more stable control ocean platform, while particle damping have controllable
The big characteristic of frequency range processed is obvious to the ocean platform excitation control effect of randomness.
2) electromagnetic induction technology is used in particle damping, kinetic energy is rapidly converted into electric energy, and then is converted into interior energy,
Simultaneously because this structural material uses heat-conducting, can be dissipated to interior rapidly in the big water of specific heat capacity, it is ingenious that consumption is utilized
Energy principle, significantly improves energy efficiency.
3) shell cavity for using hollow type, reduces opposite resistance to water-flow, can be quickly through in the case where initial wave swashs
A large amount of water flow, while the damping generated using rotary blade are reduced the intensity of first vibration, control the upheaval of total.
4) it is damped in the rotary blade cavity in the present invention containing particle, it can be on the normal impact that traditional particle damps
The bottom horizontal flow sheet direction of water flow can be changed, wash away the cavity being in communication with the outside by increasing horizontal friction and horizontal impact, rotary blade
Vertical outer surface is consumed energy；It can be consumed energy by damping particles electromagnetic induction, and increase the friction of rotation and rotating through
The effective distance of damping particles collision and friction is increased in journey.
5) trimming of airfoil water guide is used in the surrounding of cavity, is cut in upper layer and lower layer structure using the winglike of opposing face
Side, numerical simulation show that fluid dynamic energy effectively can be converted to thrust by wing, are placed on the contrary using upper and lower two panels winglike
Circular arc trimming can generate the substantially opposite thrust of size under fluid matasomatism, so that the steady plate that swings is more stable in vertical direction, machine
The edge of wing compares that traditional heave plate is thin, increases lower edges and falls off the probability of the mutual effect of impact of whirlpool, the trimming phase
Than pingbian, the contact area of structure and water is more increased, by the arrangement of viscous material, increases damping.
6) present invention surely swings plate, is increased by the number of plies, and relative size increases, and the partition amount used increases, and internal filling
Particle damping, whole self weight increases, so that the additional mass of platform increases, to increase damping.
7) present invention is just connect using upper and lower level truss structure, provides safer support while increasing loading,
The service life for increasing structure increases integral strength using truss structure, provides convenience on fixed impeller rotary shaft.
