Degree direction is evenly arranged, and 4 support arms 601,602,603,604 are arranged circumferentially in level, and two neighboring support arm is horizontal
Direction differs an angle of 90 degrees, and air can be set according to specific test requirements document on 4 support arms 602,603,604 and the top of standpipe 60
Pressure sensor 64 or piezoresistive pressure sensor 62.
The height of the standpipe 60 determines according to specific test requirements document.
Angle is 90 degree between every layer of cantilever of sensor stand, and four layers of sensor are in four mutually orthogonal directions, maximum
Limit reduces sensor interfering for the interference of BP and between itself, and most fully number is tested in collection
According to.
Measuring instrument is easy for installation, and sensor line avoids testing cumbersome repetition installation every time hardly with changing.
Preferably, the both ends of the intermediate plate 2 and side plate 31,32 respectively it is removable be fixed on main body frame 1 it is two long
Avris wall upper end, or be fixed on step and cushion block, described two shooting mouths 81,82 are located at two of main body frame 1 respectively
The middle part of short side side wall.
As shown in fig. 6, the side plate 31,32 is rectangular flat, as shown in fig. 7, the intermediate plate 2 include two it is parallel
Longeron 21,22 and vertical with longeron two crossbeams 23,24, the crossbeam both ends are connected with two side rail inners respectively, described
Two longerons and two crossbeams surround the experiment board slot 4 for accommodating breadboard 5, are set between every cross rail outer and two side rail inners
There is flat board 25,26, the upper surface of the flat board 25,26 is connected with the bottom of crossbeam 23,24 and two longerons 21,22, breadboard 5
Lower edge it is concordant with the lower edge of the flat board 25,26.
As shown in figure 8, optical glass baffle plate 7 includes optical glass 71, its periphery two sides respectively sets rubber seal 72 and steel

12 connections.
Displacement meter 63, foil gauge 61 and the sensor stand 6 installed in described supporting construction 10 are only distributed in support knot
The area of a quarter of structure 10, because experimental rig and reaction have symmetry, it is to waste all to install measurement apparatus
And it is not necessarily to.
The height of the sensor stand 6 will determine according to specific test requirements document.
Together with the step 11 is cast-in-place with the long side of main body frame 1, the bearing capacity of main body frame 1 had both been added, had been caused again
The bracket of the more conventional design in carrying of step 11 is safer.Higher point can be obtained by increasing cushion block 12 on step 11
With layer height, but lower distribution layer height can not be obtained.
The paper 64 that tests the speed is the photo at the same time interval taken using level height shooting machine, and mutually comparison obtains a certain
Diverse location during fragment different time on squared paper, so as to which the speed of the fragment be calculated.
The anti-bounce-back bolt 13 is to prevent that side plate 31,32 and intermediate plate 2 occur unexpected larger during testing
Amplitude rebounds and influences to test.
The steel construction of the sensor stand is hollow, the inside layout data line, and passes through supporting construction, therefore is being poured
During note experiment frame-types, several less holes are reserved in supporting construction, because hole is small and few, have not influenceed steel bar stress,
Therefore the influence to structural-load-carrying capacity can be ignored.
Laboratory operating procedures are：
1st, air pressure probe 64, pressure resistance type soil pressure sensor 62 etc. are calibrated, debugs high-speed camera, checks data
Circuit is gathered, guarantees to be normally carried out test measurement；
2nd, dielectric material 9 is spread in supporting construction 10, and covers side plate 31,32 and intermediate plate 2, breadboard 5 is lifted
In place.
3rd, anti-bounce-back bolt 13 is twisted, checks again for circuit and displacement meter 63 etc., checks optical glass baffle plate 7.
The 4th, explosive is placed on to the distance of test requirements document, it is ensured that explosive can smoothly be ignited, and then all personnel evacuates to peace
It is region-wide.
4th, after everything is ready, ignition charge, observed data acquisition instrument working condition and explosion phenomenon are paid attention to.
5th, after ensuring testing ground safety, explosion scene is recorded with slr camera, and measure the destruction shape of record breadboard 5
State, bolt is then unloaded, breadboard is sling and is placed on place special nearby, then intermediate plate is hung, observe and record lower section
Collapse state.
6th, all measuring instruments and circuit are checked, if there is damage to change in time.
7th, for unexpected test data and destruction situation, conscientiously to introspect to and guide and test in next step, if desired suspend
Then suspend, otherwise the repeatedly first step.
8th, the test data and phenomenon that collect are arranged and analyzed.
