Description
Technical field
Shaken the present invention relates to a kind of ship's space underframe, more particularly to a kind of can subtract with vibration damping and with generating function
Ship's space underframe, belongs to ship stabilization dampening apparatus technical field.
Background technology
Cabin dynamic power machine is the primary oscillation source of ship, vibration is passed into basis during work, then be transferred to from basis
Cabin bottom plate, produces cabin interior vibrating noise, influences normal work and the rest of crewman, crewman is also resulted in when serious and is vomitted
Tell, the symptom such as dizziness.In recent years, with the development of shipping interest, the tonnage of ship, the speed of a ship or plane and the continuous of power set power carry
It is high so that the pollution of ship's space vibration noise is increasingly serious, more have impact on the comfortableness of crewman.
In addition, ship is in the process of running, due to wind wave action, ship can be produced and waved, and waving for ship can be divided into
Rolling, pitching, vertical shake and be vertically moved up or down four kinds of forms of motion.Violent swaying can reduce the speed of a ship or plane, cause goods damage, damage hull and
Machine, makes passenger seasick, influence crewman's live and work etc..Wherein, rolling is influence ship's space internal environment comfortableness
Main factor, in recent years, with environmental degradation, the bad weather in ocean is more and more frequent so that ship is in boat in the sea
Row unstability is strengthened, and Ship Swaying is more severe, causes waving also with aggravation for ship's space, this is easily reduced crewman's work
The efficiency of work.
Ship's space vibration isolation is shaken with subtracting to shake to belong to passive vibration isolation and subtract, and is delivered to the purpose is to the vibration for reducing hull with waving
Cabin bottom plate, so as to reduce the vibration in cabin and wave, traditional method is to dispose a certain amount of vibration isolator, cloth in cabin bottom
Put after vibration isolator, there is certain vibration isolating effect to cabin, but almost without anti-rolling effect.So, research and exploration are a kind of suitable
Subtract the new technology for shaking vibration damping, new method for ship's space, have for the comfortableness and operating efficiency for improving vessel operation personnel
It is significant.Design a kind of cabin of taking into account and subtract the device for shaking vibration damping, have so as to effectively reduce cabin vibration and wave
Important engineering application value.
Application No. CN201310215233.9, the invention of entitled " ship's space leg be combined resistance shake sound insulating structure " is special
Profit, discloses a kind of ship's space leg and is combined resistance and shake sound insulating structure, including outer layer panel, nexine panel, framework, gusset, resistance
Shake mass, damping block and filler, and the framework is provided with the vibration isolation mass block being connected with framework left and right side frame, framework it is upper
Gusset that is equidistant and being connected with framework and vibration isolation mass block is vertically arranged with lower frame, the two sides of framework is connected to
Outer layer panel and nexine panel, centre form in some cavitys, cavity and are provided with filler and in outer deck panels and nexine panel
In at least one of deck panels at least one piece damping block is laid with by rule.Cabin wall structure vibration damping sound insulation work(is had both in the invention
The vibration noise inside ship's space can be effectively reduced in one, and improve the fire resistance property of cabin leg, also allowed for
Ship blockization manufacture, installation, effectively shorten the manufacturing time of ship's space fitting-out, improve efficiency of construction.Though however, the invention
A certain amount of vibration transmission can be so reduced, but the low frequency sway in cabin can not be reduced, so engineering practical value is by one

A kind of operation principle for subtracting the generating ship underframe for shaking vibration damping：
Vibration is produced when main frame or the operating of other marine machineries, these vibrations are transferred to hull again, then are transmitted by hull
To lower floor's bearing support 4, by spring 2, most of vibration can be weakened, when vibrating excessive, due to the stroke of hydraulic piston 312 limit
System, can cause vibration displacement within the stroke range of hydraulic piston 312, so as to carry out position limitation protection to cabin vibration.
Due to the effect of ship gravity and wind load, ship's space is waved and waved with hull, and this wave is a kind of big
Displacement is low-frequency to wave, and waves and is transferred to hydraulic package 3, so as to cause the upper and lower cavity of two symmetrical hydraulic cylinders 37
Occurs the flowing of hydraulic medium 315, so as to increase the torsional rigidity of cabin underframe, reduction is waved.
As shown in figure 1, relative to ship direction of advance (with shown in arrow), when cabin counter-clockwise swing, left side hydraulic pressure
Piston rod 31 is moved down, and the right liquid presses piston pole 31 is moved up, and upper left cavity and bottom right cavity become big, and lower-left cavity and upper right cavity become
It is small, cause the flowing of hydraulic medium 315.Specifically, the hydraulic medium 315 of lower-left cavity flows into upper right cavity, bottom right cavity
Hydraulic medium 315 flow into upper left cavity so that left side liquid presses piston pole 31 again move up, the right liquid presses piston pole 31 again under
Move, similarly, it is also such work that cabin, which is swung to the right, is waved so as to finally reduce.
Because cabin is waved, and cause the flowing of hydraulic package internal hydraulic pressure medium 315, and connection liquid in the middle of hydraulic tube 6
Pressure motor 51, the flowing of hydraulic medium 315 can drive the rotation of hydraulic motor 51, and the output shaft sending and receiving motor 52 of hydraulic motor 51 enters
Row generates electricity, and being connected to rectification electrical storage device 54 by wire 53 carries out electric power storage energy storage.
A kind of assembly technology for subtracting the generating ship's space underframe for shaking vibration damping：The first step, by 3 groups along cabin longitudinal centre line
Symmetrical hydraulic package 3 is fixedly attached to lower floor's bearing support 4 by bolt B 314.Second step, is carried out to all hydraulic packages 3
Hydraulic medium 315 is filled, and the correspondence of hydraulic tube 6 is connected.Specific connection method is, left side hydraulic package 3 it is upper
The lower hydraulic connector of side hydraulic connecting head connection right side hydraulic package 3, the lower hydraulic connector of left side hydraulic package 3 connects
Connect the upside hydraulic connecting head of right side hydraulic package 3.3rd step, hydraulic package 3 is rotated be connected to upper strata branch by bolt C7
The runing rest of bolster 1.4th step, two of spring 2 is respectively welded between upper strata bearing support 1 and lower floor's bearing support 4.
In the present embodiment, the quantity of spring 2 is preferably 12.Wherein, two row's springs 2 are uniformly arranged in the both sides of every group of functional unit 8,
