The control method of this two-way hydraulic propeller based on marmem, concrete control method is: controller control
Make two shape memory alloy springs and replace power on/off, drive piston past in cylinder body under the effect of shape memory alloy spring
Multiple mobile, and coordinate by controlling multiple two position three-way valve break-makes in current unidirectional distribution module so that two sparge pipes are alternately
Water spray.
For there is following several state in concrete control method:
(1) original state
Now two equal no powers of shape memory alloy spring 13.No matter whether the electric magnet of four two-bit triplet solenoid directional control valves
During energising, piston 12 is respectively positioned on the centre position of cylinder body 11, the sparge pipe 21 equal non-water flow output of two-way hydraulic jet propulsion module 2.
(2) propeller is moved to the left
As it is shown in figure 1, when the equal no power of the electric magnet of four two-bit triplet solenoid directional control valves, four two-bit triplet electromagnetic switch
Normal position (left position) work of valve.Controller, makes in rod chamber 111 driving signal to be transferred to drive circuit according to related algorithm
Shape memory alloy spring 13 heats, and promotes piston 12 to move right, and now the hydraulic pressure of rod chamber 111 declines, in rodless cavity 112
Hydraulic pressure rise.Owing to the hydraulic pressure of rod chamber 111 declines, rod chamber 111 is in vacuum state, and current are the sparge pipe in left side from figure
21 enter, and through two position three-way valve 1 and check valve 1, enter in the rod chamber 111 of cylinder body 11, due to rodless cavity
Hydraulic pressure in 112 rises, and the water in rodless cavity 112 enters into right side in figure through check valve 4 322 and two position three-way valve 4 324
Sparge pipe 21 in discharge.When the magnetostriction linear displacement transducer 14 on cylinder body 11 detects that piston 12 reaches the limit of position
After, controller driving signal to be transferred to drive circuit, makes the shape memory alloy spring in rodless cavity 112 according to related algorithm
13 heating, promote piston 12 to be moved to the left.Now the hydraulic pressure in rodless cavity 112 declines, and the hydraulic pressure in rod chamber 111 rises.By
Hydraulic pressure in rodless cavity 112 declines, and rodless cavity 112 is in vacuum state, and current sparge pipe 21 in left side from figure passes into two
Position three-way valve 3 323 and check valve 3 321, enter in the rodless cavity 112 of cylinder body 11.Due on the hydraulic pressure in rod chamber 111
Rising, the water in rod chamber 111 is in check valve 2 312 and two position three-way valve 2 314 enter into the sparge pipe 21 on the right side of in figure
Discharge.Visible, when the electric magnet no power of four two-bit triplet solenoid directional control valves, no matter piston 12 is transported to the right or to the left
Dynamic, it is all sparge pipe 21 draining on right side in figure, under the counteracting force of discharging water, promotes propeller to left movement.So control
Shape memory alloy spring 13 in rod chamber 111 processed and shape memory alloy spring 13 alternate energisation in rodless cavity 112, make
Piston 12 bilateral reciprocation, it is achieved piston 12 round trip is done work.
(3) propeller moves right
As it is shown on figure 3, when the electric magnet of four two-bit triplet solenoid directional control valves is all energized, four two-bit triplet solenoid directional control valves
Right position work.Controller driving signal to be transferred to drive circuit, makes the shape memory in rod chamber 111 according to related algorithm
Alloy spring 13 heats, and promotes piston to move right.Now, the hydraulic pressure in rod chamber 111 declines, the hydraulic pressure in rodless cavity 112
Rise.Owing to the hydraulic pressure of rod chamber 111 declines, rod chamber 111 is in vacuum state, and current sparge pipe 21 on right side from figure passes through
Two position three-way valve 1 and check valve 1, enter in the rod chamber 111 of cylinder body 11.Due to the hydraulic pressure in rodless cavity 112
Rising, the water in rodless cavity 112 enters into the sparge pipe 21 in left side in figure through check valve 4 322 and two position three-way valve 4 324
Discharge.After the magnetostriction linear displacement transducer 14 on cylinder body 11 detects that piston 12 reaches the limit of position, controller root
According to related algorithm driving signal to be transferred to drive circuit, make the shape memory alloy spring 13 in rodless cavity 112 heat, promote
Piston 12 is moved to the left.Now the hydraulic pressure in rodless cavity 112 declines, and the hydraulic pressure in rod chamber 111 rises.Due to rodless cavity 112
Hydraulic pressure decline, rodless cavity 112 in vacuum state, current from figure right side sparge pipe 21 through two position three-way valve 3 323 He
Check valve 3 321, enters in the rodless cavity 112 of cylinder body 11.Owing to the hydraulic pressure in rod chamber 111 rises, in rod chamber 111
Water enters into the sparge pipe 21 in left side in figure through check valve 2 312 and two position three-way valve 2 314 and discharges.Visible, when four two
The electric magnet of position three-way solenoid valve is when being all energized, and no matter piston is to the right or to left movement, be all in figure on the left of water spray
Pipe 21 draining, under the counteracting force of discharging water, promotes propeller to move right.So control the shape note in rod chamber 111
Recall shape memory alloy spring 13 alternate energisation in alloy spring 13 and rodless cavity 112, make piston 12 bilateral reciprocation, real
Existing piston 12 round trip acting.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent；
And these amendment or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
