It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.Under
Embodiments of the invention are described in detail with reference to accompanying drawing for face.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, is for only for ease of the description present invention and simplifies description, rather than indicate or imply signified dress
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to present invention protection
The limitation of scope.
The present invention proposes a kind of hyperbolic surface parts ballast, applies pressure loading to hyperbolic surface parts, it is ensured that load
Lasting application can be stablized.
Hyperbolic surface parts ballast of the present invention mainly includes rubber 1, wooden unit 2 and iron-clad 3, and the iron-clad 3 has recessed
Groove, and one end away from the groove is provided with auricle, one end of the wooden unit 2 is arranged to testpieces with song
The curve form that the outer surface of face shape matches, the other end of wooden unit is accommodated and is fixed in the groove of the iron-clad 3, rubber
1 laminating is arranged on one end with curve form of wooden unit 2.
With reference to Fig. 1 and Fig. 2, in the present embodiment, during to ensure to apply pressure loading to hyperbolic surface parts, load, which can be stablized, hold
Continuous application, it is necessary to assure each contact point active force is identical, and to ensure non-slip in hyperbolic surface, it is necessary first to explanation
It is that the hyperbolic surface refers to that tangent plane is in the surface of hyperbolic shape, the present embodiment refers in particular to that surface is smooth but examination of out-of-flatness
Part surface is tested, such as aircraft defends exceedingly high irdome outer surface.The structure of wooden unit 2 must be adapted to laminating on a surface, therefore, wooden unit
2 must have an end face that it can be fitted on testpieces outer surface completely, and complete fit refers to being somebody's turn to do for wooden unit 2
Arbitrfary point on end face can in the case of without external force contact test part outer surface, with reference to Fig. 1, remove beyond glue-line 6, wooden unit
2 have identical bulge-structure with the outer surfaces of testpieces/hyperbolic surface parts 6.
The other end of wooden unit 2 is fixedly mounted in the groove of iron-clad 3, and the groove of iron-clad 3 and wooden unit 2 stretch into the groove
End construction form is consistent, for example, can all be cylinder, all be square, fit system is generally interference fit, also may be used
To select the connected modes, the present embodiment such as welding, threaded connection as shown in figure 1, giving the connected mode of splicing, the cloth of glue-line 6
Put in the outer surface of wooden unit 2 or be arranged on the groove inner wall of iron-clad 3.
In alternate embodiment, the iron-clad 3 is riveted with wooden unit, perforate on the groove cell wall of iron-clad 3, and screw is described in
Perforate is simultaneously inserted in the wooden unit, for fixing the wooden unit.
In the present embodiment, the rubber 1 is glued with wooden unit 2, with reference to Fig. 1, and glue-line 6 is provided between rubber 1 and wooden unit 2.
It is understood that because rubber 1 is still suffered from testpieces outer surface because frictional force is smaller and adds carrying out load
The possibility skidded during load, rubber 1 is provided with glue-line 6 with testpieces outer surface.
In the present embodiment, the rubber includes the softer materials such as vulcanization rubber, sandwich rubber, foam rubber, is passed through with playing
Pressurized strut carries out the purpose of proportionality action power during load loading.
In the present embodiment, as shown in Fig. 2 iron-clad 3 is provided with auricle, such as monaural or double in one end away from groove
Ear, the end of pressurized strut 5 is connected to by bearing pin.
It is hyperboloid structure that aircraft, which defends exceedingly high irdome outer surface, when doing slow test, and pulling force is born at rear portion, and front portion is born
Pressure, this structure is employed when front portion applies pressure loading, loading is divided to or so two load(ing) points, is first sticked at load(ing) point
One layer of rubber, according at load(ing) point External Shape make two pieces of triangle wooden units, then do two with wooden unit cooperation metals connect
Jacking block is pasted onto on rubber by capitiform into jacking block, and pressurized strut is connected with jacking block, is loaded using this transition structure, load
From 0~120%, whole process is accurately, stably, safely.
The present invention is first pasting one layer of rubber on testpieces surface, then the wooden unit with profile is pressed on rubber, wooden unit top
Upper one metal joint of band, metal joint is connected with pressurized strut, piece surface, rubber and wooden unit is connected together with gluing,
Pressure loading is applied in hyperboloid piece surface with this, accurately, stably, continuity is good, protects loading system and testpieces, greatly
Experimentation cost is saved greatly.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
