Specific embodiment
The present invention is described further with reference to the accompanying drawing.
Embodiment 1:
A kind of model test apparatus for simulating submarine ice-breaking replaces the buoyancy of submarine using the elastic force of spring, is surveyed by spring
Power, which measures, measures the elastic force of spring, i.e. the resultant force size that act on submarine of water, the size and ice of stress when observation ice sheet destruction
The destruction situation of layer.Its principle is relatively simple, with one piece of rectangular block come command set when simulating submarine ice-breaking with ice sheet effect.Examination
Experiment device systematization, it is easy to operate.In addition, being equipped with the track slided up and down in experimental tank front and rear sides, controlled with this
The compression of spring processed increases spring to the pressure of plate, and simulation submarine floating discharges increased buoyancy, i.e. submarine when ballast and acts on
Power on ice sheet.
Embodiment 2:
A kind of model test apparatus for simulating submarine ice-breaking, is mainly used in submarine ice-breaking mechanism study and submarine ice-breaking
Journey simulation, including the experiment pond with glass sides, slideway, the bracket being mounted on slideway, weight beam, hanging ring, branch
The box of spring is supportted, spring simulates the rectangular block of submarine command platform.Experiment pond with glass sides lies in a horizontal plane in floor
On, ice is placed in experimental tank, and squeezes into sunpender on four angles of ice cube, and the horizontal stripe being connected with sunpender is fixed on pond two
The ice sheet that submarine is faced in polar region ice-breaking is simulated with this to limit moving up and down for ice sheet in side.Slideway is mounted on glass
The front and back front end in the experiment pond of glass side, bracket are mounted on slideway, and weight beam is rack-mount.Hanging ring is fixed on
On the box of support spring, the box of support spring is hung in below weight beam by hanging ring.The spring one end side of being connected to
On frame inner wall, the rectangular block of other end connection simulation submarine command platform.When test, first ice sheet is fixed, is slowly moved up
Bracket, rectangular block will receive the obstruction of ice sheet and can not move up, and spring starts to continue to compress at this time, and rectangle BOB(beginning of block) is to ice
Layer has squeezing action, by the change before and after observation dynamometer registration, can calculate rectangular block to the pressure size of ice sheet, into
One step compressed spring observes the destruction situation of ice sheet until ice sheet destroys.
The configuration of the present invention is simple simulates increased buoyancy when submarine floats using simple spring-compressed, and cost is relatively low.
Ice sheet stress when submarine floats can not only be simulated, and there is a situation where destroy, moreover it is possible to by changing the length of two dynamometers, mould
Ice-breaking situation when quasi- submarine trim floats, experimental rig folding and unfolding is simple, operates conveniently.
Embodiment 3:
As shown in Figure 1 and Figure 2, in figure with glass sides 1 fixed placement of experimental tank on a horizontal ground, ice cube 8
It floats in the water of the experimental tank 1 with glass sides.Sunpender 9 is fixed together with ice cube 8, and sunpender 9 is connected with horizontal stripe 10,
Horizontal stripe 10 is fixed on the two sides of the experimental tank 1 with glass sides.Before slideway 2 is mounted on the experimental tank with glass sides
Both ends afterwards, bracket 3 are installed on slideway 2.The upper end of weight beam 4 is connected with bracket 3, and hanging ring 11 is fixed on the side of support spring
On frame 5, the box 5 of support spring is hung in the lower end of weight beam 4 by hanging ring 11.One end of spring 6 is mounted on support bullet
On the inner wall of the box 5 of spring, the other end of spring 6 is connected with the rectangular block 7 of simulation submarine.
When experiment, weight beam 4 is nested together and is fixed with hanging ring 11, hanging ring 11 is avoided to go out during the test
Now wave.The position that is connected with ice cube 8 of sunpender 9 is handled well, avoids the occurrence of loosening, horizontal stripe 10 is fixed on the test with glass sides
1 two sides of pond, to realize the simulation of submarine big ice sheet in polar region ice-breaking.The registration of weight beam 4 when recording initial,
The slowly mobile bracket 3 being mounted on slideway 2 records weight beam 4 this moment when rectangular block and ice sheet just start to contact
Registration, continue to move up bracket 3, the deformation of the registration variation and ice sheet of observation weight beam 4, until ice sheet is sent out
It is raw to destroy, observe the failure mode of ice sheet.It can be calculated by the front and back variation of 4 registration of weight beam and act on ice sheet
