Following present a kind of structural representation of Fluid pressure charger.
Incorporated by reference to reference to Fig. 2, Fig. 2 is that in a kind of specific embodiment of the present invention, Fluid pressure loads
The structural representation of device；Wherein, illustrate only both direction in Fig. 2 to load, vertical direction
And horizontal direction.
Specifically, in a kind of specific embodiment, Fluid pressure charger 4 includes body 41,
Sample containing cavity 4a, at least one fluid media (medium) chamber is offered, sample houses inside body 41
Chamber 4a is used for accommodating and fixing sample；The inside in each fluid media (medium) chamber is all equipped with piston, and piston will
Corresponding fluids dielectric cavity is isolated into two chambers, and wherein one chamber passes through the internal setting of body 41
Oil communication external hydraulic medium, another chamber sample containing cavity 4a, and each piston court
Can extend inside sample containing cavity 4a to one end of sample containing cavity 4a；Fluid media (medium) chamber and work
Plug forms and loads cylinder.
Sample, when sample is carried out with power loading, is placed in charger by this embodiment first
The inside of body 41, then drives fluid media (medium) intracavity within to body 41 for the external agency source
Fluid media (medium) is filled in portion, under the promotion of incoming fluid dielectric cavity fluid media (medium), is placed in fluid media (medium)
The piston in intracavity portion moves towards sample containing cavity 4a, with the continuous injection of fluid media (medium), piston
Against sample and apply certain power in sample.Operator can be according to fluid media (medium) in pipeline
Pressure, piston area, calculating put on power on sample, thus realizing the loading of sample power.
This sample power load mode passes through the embedded cylinder that loads provides the pressure of different directions, with liquid
As a example body medium, pressure can reach 200mpa, and can achieve three axles, two axles, single shaft
Load test, charger is relatively simple for structure, and volume can mate sample design.
Wherein, body 41 can be manufactured using high-strength light aluminum alloy materials, had both met big load
Lotus writes the intensity requirement of body 41, has the requirement that when meeting ct scanning, ray penetrates, also
Reduce tank body to conduct oneself with dignity to meet the requirement that turntable limits to scanned copy weight.
When the power on sample that puts on is two dimension mutually vertical forces (two axles), fluid is situated between
The corresponding quantity in matter chamber is two, respectively first fluid dielectric cavity 4b and second fluid dielectric cavity
4d, accordingly described piston specially first piston 42 and second piston 47, first piston 42 is put
In the inside of first fluid dielectric cavity 4b, second piston 47 is placed in second fluid dielectric cavity 4d
Inside, and first piston 42 is axially and the axially vertical arrangement of second piston 47.Herein
In the horizontal direction, second piston 47 is axial vertically for first piston 42, certainly, first
The axial direction of piston 42 and second piston 47 can be arranged according to the demand of actual loaded power.
When simulating three-axis force, fluid media (medium) chamber also includes the 3rd fluid media (medium) chamber, and the described 3rd
The inside in fluid media (medium) chamber is also equipped with the 3rd piston, and axial, described the second of described 3rd piston
The axial direction of axial, the described first piston of piston constitutes three-axis reference.Though not providing herein the
The schematic diagram in three fluid media (medium) chambeies, but the word description according to this paper, technology people in the art
Member is readily appreciated that and carries out implementing this technical scheme.
Further, in order to sample is obtained than larger loading with less loading cylinder interior pressure
Plunger designs can be variable cross-section, that is, the cross sectional dimensions of the first end face of piston are more than by power
The cross sectional dimensions of second end face, described first end face is the end face towards fluid media (medium) end,
Described second end face is the end face towards described sample containing cavity 4a end.
In actual tests, the operating pressure loading cylinder interior is less, and oil pipe connects and pump
Pressure is easier to meet, and the pressure ratio being added in sample is larger, facilitates implementation larger adding
Load power, does not affect ray particularly with z direction (vertical direction) this part and penetrates, for chi
Very little no particular/special requirement.
In addition, for x, y both direction loads, on the premise of ensureing loading force size, also
To reduce impact when ray penetrates, sample being produced, the therefore overall dimensions of body 41 will as far as possible
Sufficiently small, but it has to be ensured that its experiment load, therefore work in-process, body 41 adopts non-
