A kind of air bubble multitube mass-sends moveable platform
Technical field
The present invention relates to a kind of bird impact tests device of aviation field, and in particular to a kind of air bubble multitube mass-sending is removable
Platform.
Background technology
Aircraft is often possible to encounter the small bird of flight in high-altitude flight, and " bird knocks machine away " is currently global problem.
Counted according to International Airways Association, since 1912, bird, which is hit, at least results in the accident of 63 frame civil aircrafts;Military spacecraft speed
Hurry up, bird hit harm it is even more serious, since nineteen fifty document record major accident more than 353, at least 165 people are wrecked.
Why at most several kilograms of a weight, the relatively slow bird of flying speed, it can be contrasted and much huge flown
Machine causes so big injury, and " bird knocks machine away " described in us is actually that " aircraft hits bird, " problem has its source in aircraft
Operating high speed, rather than the quality of birds in itself.According to momentum theorem, 800 kilometers of one 0.45 kilogram of bird and speed per hour
Plane collision, 153 kilograms of impulsive force can be produced;One 7 kilograms of curassow is hit on the aircraft of 960 kilometers of speed per hour, impact
Power is up to 144 tons.
High-speed motion makes the destructive power of bird reach surprising degree, and a sparrow just is enough to smash aircraft engine during landing
Machine.And the biological nature of birds, it is determined using distance rather than speed as the judgment standard of " whether flying away ", but the height of aircraft
Speed allows it also to have little time to react, and has reformed into " assailant " and victim.
Bird in face of taking place frequently hits aircraft accident, and aircraft can be taken when manufacturing and be doomed defensive design, can to aircraft
It can be launched by the parts of bird collisions using air bubble and hit dynamics progress stress performance test to imitate bird.But the current country is directed to
The emitter of air bubble, substantially single tube fix single tube transmitting, can not simultaneously on testpieces carry out larger area by
Power performance test.
The content of the invention

The lower end inside of two longitudinal framing body columns 211 is symmetrically connected with horizontal beam 213, the inner of horizontal beam 213 and standing for corresponding side
Cant beam 214 is connected between post 211.
Support frame 21 is removably connected to longitudinal branch by the connecting plate 215 of the downside of horizontal beam 213 and the bottom of column 211
The upper end of support 13.
Column 211 and crossbeam 212 are made using rectangular tube, and the inner side of column 211 up connects from the junction of cant beam 214
Longitudinal porous plate 216 is connected to, the width of longitudinal porous plate 216 is more than the width of column 211, and its length direction both sides opens up respectively
There is row's connecting hole.
Can be seen that guide assembly 22 with reference to Fig. 2, Fig. 4 and Fig. 6 includes upper rail 221, lower guideway 222 and leads upper and lower
The end connecting seat 223 and middle part connecting seat 224 that rail connects as one, upper and lower rails position correspondence are arranged in parallel, above led up and down
Rail 221 is cold drawn chromium plating pole, and lower guideway 222 is rectangular tube.
Can be seen that end connecting seat 223 with reference to Fig. 2, Fig. 4, Fig. 6 and Fig. 8 includes lower connecting base 2232 and upper connecting base
2231, lower connecting base 2231 is L-type seat, and upper connecting base 2231 is T-shaped seat;Upper connecting base includes pedestal and pressing plate;Lower connecting base
2231 are connected fastening by riser with the connecting hole on longitudinal porous 216 plate.The pedestal of upper connecting base 2231 and lower guideway 222
End is connected to the upper side and lower side of the level board of lower connecting base 2231, the pedestal upper end and pressing plate lower end of upper connecting base 2231
Corresponding position has circular groove, two circular grooves fixed after upper rail 221 is clamped respectively.Above and below guide assembly 22
Position changes to be realized by connecting the connecting hole of different height position on longitudinal porous plate 216.
Can be seen that middle part connecting seat 224 with reference to Fig. 2, Fig. 4 and Fig. 6, Fig. 9 includes upper connecting base 2231 and lower fixed seat
2241, lower fixed seat 2241 includes level board and the supporting plate being symmetrically connected on the downside of level board, and level board is welded in lower guideway
222 upside, supporting plate and a pair of sidewalls of lower guideway 222 are welded;Upper connecting base 2231 clamps fixed upper rail 221.
Can be seen that gun tube secured adjusted component 235 with reference to Fig. 2, Fig. 4, Fig. 6 and Fig. 7 has some groups, each guide assembly
Multigroup gun tube secured adjusted component 235 is connected on 22, every group of gun tube secured adjusted component 23 is included from the bottom up successively
Π types connecting seat 231, slidable adjustment seat 232, adjusting screw rod 233 and the adjusting nut 234 and gun tube fixed seat 235 of arrangement.
Gun tube fixed seat 235 includes bedplate 2351, riser 2352 and gland 2353, and riser 2352 is vertically connected at base
On the length direction median plane of plate 2351, gland 2353 is placed on the upper end of riser 2353, passes through the upper end of riser 2352 and gland
The arcuate socket of 2353 lower ends is fixed after gun tube is clamped.The length direction both sides of the top plate of Π types connecting seat 231, which are symmetrically connected with, wears
The guide rod 236 of slidable adjustment seat 232 is crossed, guide rod both ends pass through nut lock with Π types connecting seat and gun tube fixed seat respectively
Tightly.Adjusting nut 234 is welded on the median plane on the downside of the length direction of bedplate 2351, the upper end of adjusting screw rod 233 and regulation
Nut 234 connects as one, lower end peaks at the upper end of slidable adjustment seat 232.
Lower guideway 221 passes through from the clip slot of Π types connecting seat 231, and upper rail 221 is linked as one from slidable adjustment seat 232

The upper end of bar 233 connects as one with adjusting nut 234, lower end peaks at upper end with slidable adjustment seat 232, adjusting nut 234
Center screw length be more than adjusting screw rod 233 screw thread segment length.The side wall of adjusting screw rod 233 has the circular hole of radial direction, can lead to
Cross through the boosting-rod in circular hole to rotate adjusting screw rod 233, make adjusting nut 234 drive gun tube fixed seat 235 to change up and down
Position, to ensure the axiality of gun tube.
It is connected between can be seen that the column 211 of the both sides relative position of support frame 21 with reference to Fig. 2, Fig. 4 and Fig. 6
Multigroup parallel guide assembly 22, the multigroup gun tube to stagger position is connected on neighbouring guide assembly 22 fixes and adjust
Save component 23.
The cross-brace frame and longitudinal bracing frame of the present embodiment base platform component only have one layer respectively, other implementation situations
Cross-brace frame and longitudinal bracing frame can be combined height as needed.
The change of shell bomb-release point position realizes that the lateral attitude of gun tube of the present invention, which changes, to be led to by adjusting the position of gun tube
Cross position realization, lengthwise position change of the adjustment gun tube secured adjusted component on guide rail and pass through guide assembly on the support frame
Link position and the longitudinally adjust of gun tube secured adjusted component be engaged realization.Guide assembly connects height on the support frame
Change realize the larger adjustment of gun tube height and position, gun tube secured adjusted component realizes the small adjustment of gun tube height and position.It is first
First pass through guide assembly and carry out larger position adjustment, be then finely adjusted by gun tube secured adjusted component, ensure each
Gun tube it is front and rear with one heart, so as to ensure the smooth transmitting of gun tube, to testpieces imitate flock of birds hit carry out stress performance test, fill out
Mend the blank of current technology.
