Description
Technical field
The present invention relates to a kind of instruments used for education for demonstrating free surface effect, ship model, upset are specifically employed
The structure such as plate and multistage rotating disk, the experimental facilities of influence that can be with analog demenstration free surface effect to ship belongs to teaching and uses
Product field.
Background technology
Free surface effect refers to liquid and Small Solid, and the aggregation response wave and wind-force of such as seed or sandstone draw
, there is the phenomenon that posture changes in the freight house, deck or liquid storage tank in ship in the effect of hair and the situation of hull.Free surface
Effect is to cause one of the key factor of overturning of vessel, is ocean, machinery and ship domain major issue urgently to be resolved hurrily.But
The current teaching aid on free surface effect is unfavorable for colleges and universities and research institution to free surface still in the state of blank out
The cognition and popularization of effect.Therefore, a teaching equipment that can demonstrate the influence that free surface effect is caused to ship is researched and developed
As exigence.
The content of the invention
For above-mentioned deficiency, the invention provides a kind of instruments used for education for demonstrating free surface effect.
The present invention is achieved by the following technical solutions：A kind of instruments used for education for demonstrating free surface effect, are by reality
Test frame, returning face plate, ship model, preserving jar, channel bar frame, channel bar, multistage rotating disk and solid filler composition, it is characterised in that：
Returning face plate is arranged between the hole opened on experiment frame, and multistage rotating disk is arranged on experiment frame, is driven by motor, one end peace of channel bar
In any one hole of multistage rotating disk, in other end insertion groove bridge, ship model is placed on returning face plate, and preserving jar is laid
On ship model, solid filler is placed with preserving jar.
There is projection and pore structure respectively, the projection of ship model bottom is inserted into upset on described ship model and returning face plate
In hole on plate, the position of fixed ship model.
To be hinged between described multistage rotating disk and channel bar, channel bar can be rotated relative to multistage rotating disk, and the other end of channel bar can
Opposed slot bridge is slided, and the cylindrical protrusion on experiment frame is passed through in the groove of channel bar.
Several apertures are radially provided with described multistage rotating disk, can be installed with the one end fits of channel bar；Multistage rotating disk turns
It is dynamic, drive channel bar to swing, the channel bar other end drives returning face plate side-to-side vibrations by channel bar frame.
The usefulness of the invention is, using model ship, can be with vivid simulation free surface effect to ship
Influence, experimental result is intuitively three-dimensional；Multistage rotating disk is radially provided with several apertures, is connected from different apertures by channel bar, can
To be classified the Oscillation Amplitude of regulation returning face plate, operation is flexible；Experimental provision simple structure, is easy to installation and maintenance, and component is simple
Image, is conducive to the understanding and operation of student.

Specific embodiment
A kind of instruments used for education for demonstrating free surface effect, are by experiment frame 1, returning face plate 2, ship model 3, preserving jar 4, groove
Bridge 5, channel bar 6, multistage rotating disk 7 and the composition of solid filler 8, returning face plate 2 is arranged between the hole opened on experiment frame 1, many
Level rotating disk 7 is arranged on experiment frame 1, is driven by motor, and one end of channel bar 6 is arranged in any one hole of multistage rotating disk 7, separately
In one end insertion groove bridge 5, ship model 3 is placed on returning face plate 2, and preserving jar 4 is placed on ship model 3, is placed with preserving jar 4
Solid filler 8.
There is projection and pore structure respectively, the projection of the bottom of ship model 3 is inserted on described ship model 3 and returning face plate 2
In hole on returning face plate 2, the position of fixed ship model 3.
To be hinged between described multistage rotating disk 7 and channel bar 6, channel bar 6 can be rotated relative to multistage rotating disk 7, channel bar 6 it is another
End can opposed slot bridge 5 slide, the cylindrical protrusion on experiment frame 1 through channel bar 6 groove in.
Several apertures are radially provided with described multistage rotating disk 7, can be installed with the one end fits of channel bar 6；Multistage rotating disk 7
Rotate, drive channel bar 6 to swing, the other end of channel bar 6 drives the side-to-side vibrations of returning face plate 2 by channel bar frame 5.
The device is placed the device on horizontal table top or workbench when in use, first, and solid filler 8 is put into storing
In tank 4, one end of channel bar 6 is connected on the aperture nearest from the center of circle of multistage rotating disk 7, starting motor rotates multistage rotating disk 7,
Now the Oscillation Amplitude of returning face plate 2 is minimum, and ship model 3 will not topple；Stop multistage rotating disk 7, one end of channel bar 6 is connected to from many
On the remote aperture of some in level rotating disk 7 center of circle, motor is started, now the Oscillation Amplitude of returning face plate 2 becomes big, then observe the meeting of ship model 3 not
Can topple；Said process is repeated, until ship model 3 topples, record makes ship model 3 topple corresponding aperture series.Again by solid
Filler 8 takes out, and to injection in preserving jar 4 and the contour clear water of solid filler 8, repeats to test above, records aperture series.
By comparing it can be found that the corresponding aperture series that topples of ship model 3 in preserving jar 4 for solid filler 8 is greater than storing
Ship model 3 in tank 4 for clear water topples corresponding aperture series.The stabilization of ship can be reduced when illustrating in preserving jar 4 as liquid
Property, it is easier to make overturning of vessel, also just demonstrate free surface effect.
For the ordinary skill in the art, teaching of the invention, do not depart from principle of the invention with
In the case of spirit, the changes, modifications that are carried out to implementation method, replace and modification still fall within protection scope of the present invention it
It is interior.
