Description
Technical field
The invention belongs to primary and secondary class warhead test equipment fields, are used for more particularly, to what a kind of energy was reused
The trial assembly for testing impact acceleration of the bullet during shedding is put.
Background technology
Be presently used for strike ground large area target guided missile or guided rocket bullet polygamy for primary and secondary class warhead, bullet
It is seated in inside female body, bullet is shed into out housing when apart from ground certain altitude, target is killed.
Bullet will be subjected to larger transverse direction or axial impact overload during housing is shed out, be needed in development and design
The impact acceleration size suffered by it is tested, is improved for data analysis with design and foundation is provided.Simultaneously as impact during experiment
Power easily damages test cable or the sensor body that sensor carries, once test cable and sensor connector partial destruction,
It will cause scrapping for sensor.And the bullet quantity of single test test is generally more, and test number (TN) is also more, it is desirable to
Test equipment can possess the function of reuse.
For more than technical problem, some schemes for attempting to solve have been proposed in the prior art.For example, inside bullet
It arranges wireless impact acceleration test device, is mounted on after coating protection comprehensively to test device with padded coaming inside bullet, both
Impact acceleration can be tested, and physically eliminates the test cable for causing sensor degradation.
However, said program still has following deficiency：Wireless impact acceleration test device cost is higher, before use
It needs to charge to internal cell, having time limitation is tested to since charging complete.
Therefore, it is necessary to develop a kind of bullet impact overload measurement device of low cost, easy to use, timeless.
The content of the invention
For the disadvantages described above or deficiency of the prior art, present invention aims at provide a kind of bullet impact overload measurement dress
It puts, in structure, sensor support base combination transit cable and cable tabletting so that g sensor can also after having performed test job
Reuse, accordingly so that apparatus of the present invention it is of low cost, it is easy to use, without because battery charge when in use between it is upper limited
System.
To achieve the above object, the present invention provides a kind of bullet impact overload measurement device, including sensor support base, mistake
Set sensor, test cable, transit cable and cable tabletting, wherein,
The sensor support base is prepared for polymer composite, is fixed on bullet shell body inner wall, the mistake
Set sensor is fixed on sensor support base, and the test cable is connected to form entirety with the g sensor, the switching
Cable one end is connected with the test cable by adapter, and the other end and extraneous test equipment connect extraneous test equipment
One ends wound in cable tabletting, the cable tabletting is also secured on the bullet shell body inner wall.
Further, the polymer composite for preparing the sensor support base is the phenolic aldehyde tree of fiber cloth enhancing
Fat.
Further, the cable tabletting is arc-shaped, for matching the bullet shell body inner wall shape.
Further, the cable tabletting is fixed on by attachment screw on the bullet shell body inner wall.
The bullet that apparatus of the present invention can test when cluster warhead is shed radially overloads, and protects g sensor and its survey
It is not damaged to try cable, equipment coefficient of losses can be reduced while test parameter is obtained, improves the practicability of equipment.
In general, following advantageous effect can be obtained by the above technical scheme conceived by the present invention：
G sensor is installed by the sensor support base of lightweight non-metallic material in test device of the present invention, is reduced
Intermetallic contact vibration impact, while the test cable of sensor existence will be influenced by transit cable connecting test equipment,
Transit cable is broken by the influence of cable tabletting when shedding, and protection sensor cable is injury-free, reduces use
Cost, g sensor can also be reused.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.As long as in addition, technical characteristic involved in the various embodiments of the present invention described below
Conflict is not formed each other to can be combined with each other.
Fig. 1 is the front view that the bullet impact overload measurement device mounting structure of present pre-ferred embodiments is illustrated；Fig. 2 is
The top view of the bullet impact overload measurement device mounting structure schematic diagram of present pre-ferred embodiments；Fig. 3 is preferable for the present invention
The another top view of bullet impact overload measurement device mounting structure schematic diagram of embodiment.According to above three figure, the present invention
Bullet impact overload device includes sensor support base 2, g sensor 3, test cable 4, transit cable 5, cable tabletting 6 and connects
Connect screw 7.
Wherein, sensor support base 2 is connected by attachment screw 7 and bullet shell body 1；G sensor 3 passes through the company that carries
It connects screw thread and sensor support base 2 connects；It is fixed on after test cable 4 and transit cable 5 connection that sensor carries in bullet
Portion；It is connected after transit cable 5 is circumferentially wound in cable tabletting 6 with test equipment；Cable tabletting 6 passes through attachment screw 7 and son
1 phase of body is fixed.
Sensor support base 2 is lightweight non-metallic materials, can be for example specifically phenol aldehyde laminated cloth rod with phenolic resin, density
For 1.26g/cm3, compression strength 137.9Mpa, breakdown voltage 10Kv.
The course of work of apparatus of the present invention is：
More pieces of bullets are simultaneously in female bullet, and when carrying out shedding experiment, female bullet is fixed on experimental rig, central charge
After detonation, bullet is shed, and bullet is subject to detonation impact force at this time, and bullet outwards disperses, the overload sensing inside bullet
Device and cable etc. can be subject to strong impact, and transit cable 5 is caused to be broken at 6 winding of cable tabletting, so as to play protection
Test cable 4 is from the effect of damage, and test cable 4 and g sensor 3 are an entirety, and test cable 4 does not damage, so as to
G sensor 3 during follow-up test is enable to reuse.During reuse, transit cable 5 is only replaced.
In apparatus of the present invention, transit cable 5 is the weak spot of stress at 6 winding of cable tabletting, non-after bullet is shed
Often it is easily broken off.Be equivalent to extend on original test cable 4 and one section of transit cable 5, then on transit cable 5 design by
Power weak spot so that the point being easily broken off on test cable 4 has enough time being broken not yet, and transit cable 5 just has occurred and that fracture,
Test terminates, and has the function that protect g sensor.
A kind of bullet impact overload measurement device of the present invention, for testing when primary and secondary class warhead bullet is radially shed
Impact acceleration, and sensor body is protected to preserve from, it solves existing bullet impact overload and is difficult to test, and sensed after testing
The problem of device damage can not be continuing with.Which obviate the problem of wireless impact acceleration test device cost is higher, without will
Charge to internal cell, when in use between on also there is no limit.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, all any modification, equivalent and improvement made within the spirit and principles of the invention etc., should all include
Within protection scope of the present invention.
