Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Adjustable marine environment experiment boundary condition simulation device, comprise marine environment simulation system, motion platform and be positioned at and motion platform treats examining system, describedly treat that examining system comprises internal pipeline, described marine environment simulation system is separated placement with motion platform, described marine environment simulation system comprises the first side direction interface, and described motion platform comprises the second side direction interface; Described second side direction interface with treat that examining system is fixedly connected with, but be not fixed on motion platform;
Described first side direction interface is connected by flexible link with the second side direction interface; Described flexible link is fluid pipeline; The internal diameter of described first side direction interface, the second side direction interface and flexible link is all greater than more than ten times, any pipeline of internal system to be measured.
Provide a kind of embodiment of the present invention as shown in Figure 1, in Fig. 1, the left side is marine environment simulation system pond 1, can be such as possess the open pond or sealing type cistern of making unrestrained function, be provided with the first side direction interface 2 on border, pond, the fluid Movement transmit in marine environment simulation system pond 1 can be treated in examining system to motion platform.Side direction interface is by water pool inner water to motion platform system transmission, if under making unrestrained condition, then the flow transmitted changes in time, if water pool inner water is static, then and stability of flow.
For motion platform 6 with to be arranged on motion platform 6 to be tested treats examining system 5 on the right of Fig. 1, motion platform is provided with the second side direction interface 4, first side direction interface connects the second side direction interface by flexible link, the ocean simulation border of marine environment simulation system inside expands to motion platform by the transfer device be made up of the first side direction interface 2, second side direction interface 4 and flexible link 3, make the fluid in marine environment simulation system be delivered to loading on the moving platform treat in examining system, realize treat examining system inland sea ocean environment real simulation.
Motion platform self can six-freedom motion, but marine environment simulation system pond can not be positioned over because its load-bearing capacity is limited, therefore, originally can not move in static land in pond, but by appropriate design interface size, ensure that its water capacity and actual internal area are much larger than system interface pipeline to be measured, relative to treating the marine environment that can regard as large space for examining system, and utilize the same motion platform that is flexible coupling to be connected, in this, as the extension on marine environment border, pond inner fluid enters in motion platform system, can move together along with motion platform, solve land seawater and be delivered to problem on motion platform.
So-called six degree of freedom is three one-movement-freedom-degrees, three rotational freedoms, the coupled motions that six-freedom motion is three one-movement-freedom-degrees, three rotational freedoms and multiple single movement state superpose formation mutually.
Motion platform can carry out six-freedom degree motion by self hydraulic drive, the motion state of hull in simulation ocean; On motion platform, object to be measured is equivalent to heat transmission equipment in simulation hull, as heat interchanger, remaining row's heat interchanger etc.; In marine environment simulation system, aqueous medium is delivered in the Devices to test in motion platform by patent mode of the present invention, is namely equivalent to heat transmission equipment secondary side seawater in simulation hull.
Wherein, internal system to be measured comprises various pipeline, such as treat that examining system is engine of boat and ship, then may have oil plant pipeline, ooling channel, compressed gas pipeline etc., the internal diameter of the pipeline of the first side direction interface, the second side direction interface and flexible link should much larger than above-mentioned internal system pipeline maximal value to be measured, more than at least ten times, comparatively ideal marine environment can be regarded as relative to treating for examining system.
Flexible link is fluid pipeline, the metal hose that such as corrosion resistivity such as corrugated tube, flexible metal conduit is strong, the height of the first side direction interface is according to treating that the actual depth of water of examining system is determined, when examining system is in overwater service for a long time, then the first side direction interface is arranged on water surface position, until examining system be in for a long time underwater or comparatively depths time, then the first side direction interface height is arranged on corresponding depth of water place.For simulating different depth of water height simultaneously, the first side direction interface that multiple depth of water is different can be set, can simulate and dive with the different water depth treating examining system.Second interface to be measured is normally horizontally disposed with, described second side direction interface with treat that examining system is fixedly connected with, but be not fixed on motion platform, second interface to be measured freely can be promoted by the liquid thrust in flexible link, drive system motion to be measured, realize sea situation simulation, employing flexible link can also cushion the direct collision between the first side direction interface and the second side direction interface, stable motion platform.
Marine environment simulation system is the ocean that simulation possesses the suitable depth of water, usually possess suitable height, be significantly higher than the cumulative height treating examining system and motion platform, for convenience flexible link be installed, the interface section of the first side direction interface can be downward-sloping, is greater than 45 degree with horizontal direction angle.
Flexible link can adopt with the first side direction interface and the second side direction interface and weld and Flange joint, can also arrange buffer spring in junction, to reduce the probability of flexible link because of impaired movement.
