The connection structure between the wall blocks 101 is stable, construction is convenient, and the design of the insertion blocks and the slots can change in various structures according to the situation.
After the projectile explodes, fragments fly out in a certain direction, and the distribution condition of the fragments in space is an important factor influencing a fragment killing action field. When multiple projectiles are stacked together and detonated simultaneously, the distance between the projectiles becomes smaller, potentially preventing the casing from expanding to the maximum velocity radius. In addition, when the fragments are scattered, the fragments may collide with each other, which may not only reduce the scattering speed of the fragments and change the scattering direction of the fragments, but also cause the fragments to be re-crushed and form new fragments, which may affect the quality, speed and spatial distribution of the final fragments. The research result shows that: the fragment distribution of the multiple shot in the explosion has the same rule as that of the single shot in the explosion, but the fragment flying density distribution probability of the multiple shot is smaller than that of the single shot in the normal direction of the shot axis.
After the fragment is formed, when the pressure of the detonation product acting on the fragment is balanced with the air resistance on the fragment, the velocity of the fragment reaches the maximum value, and the velocity of the fragment is called the initial velocity of the fragment. The initial speed of fragment is an important parameter for measuring the killing power of the projectile, so that the calculation is required to be performed as accurately as possible.
The utility model discloses once destroy ammunition TNT equivalent control within 50kg, ammunition will bury in the soil pit of degree of depth 1 meter during destruction, confirm danger radius region and personnel safe distance with the distance that flies apart of single shot blasting back fragment during consequently calculation.
The type of fragment generated after an explosion is related to the structure of the warhead. As most ammunition adopts a non-prefabricated fragment warhead, only natural fragments with irregular shapes and qualities are generated after detonation. Therefore, the present study sets the safe distance by calculating the fragment flying distance with non-prefabricated fragment ammunition.
Because the ammunition that most were treated to destroy belongs to cylindrical symmetrical structure, so the utility model discloses a cylindrical powder charge Gurney formula calculates the initial speed of rupture of a piece:
in equation 1-1: c is the projectile body charging quality, M is the projectile body quality,
the Gernik constant of TNT is 2438 m/s.
The criterion for killing the personnel by the fragments comprises a kinetic energy criterion, a specific kinetic energy criterion, a fragment quality criterion, an A-S criterion and a fragment distribution density criterion. The probability that a person is damaged by a fragment under the condition of no protection is suitable as a safety standard. Researchers in China think through research that the fragment function of more than 98J can cause killing effect to personnel.
According to the minimum personnel killing criterion, when the fragment kinetic energy E =98J, calculating the fragment storage speed at the moment:
the motion speed attenuation formula of the fragments in the air without considering gravity is as follows:
in equations 1-2 and equations 1-3: v0The initial speed of the fragment is; m isfThe fragment quality is obtained; cxIs the fragment resistance coefficient; rhoairIs the local air density;
the frontal area of the broken pieces; r is the flight distance of the fragments;
in order to reduce the fragment flying distance and the explosion noise, the ammunition to be destroyed is arranged in an explosion pit with a certain depth so as to increase the flying angle alpha of the fragments.
Thus, there are equations 1-4:
finishing 1-4 to obtain formula 1-5:
according to the characteristics of a parabolic trajectory in vacuum, the shot distance of the projectile is farthest when the firing angle is 45 degrees, so that the fragment flies farthest when the fragment flies out by taking the included angle between the far end of the initiation point and the top end connecting line of the wall of the detonating tower as the maximum flying angle.
When the design of the detonating tower is carried out, two destroying layout modes are considered, the first mode is that a detonating point I4, a detonating point II 5 and a detonating point III 6 are respectively arranged at three vertexes of an equilateral triangle, and the second mode is that a detonating point IV 7 is arranged at the center of the equilateral triangle.
No matter what arrangement mode the explosion points are arranged, the flying fragments at the surface close to the wall surface of the detonating tower are blocked by the wall surface of the detonating tower and fall back to the explosive personnel, and the flying fragments at the surface far away from the wall surface of the detonating tower are partially explosive. Therefore, the fragment flying angle alpha is considered when calculating the fragment flying distance in the detonating tower.
The correlative analysis and calculation are carried out on four army common typical large-caliber bomb species of 155 mm bomb, 152 mm grenade bomb, 130 mm bomb and 122 mm bomb.
Because the four types of ammunition are destroyed by adopting the ammunition natural fragments, aiming at the four types of ammunition, according to the classification method of the ammunition body fragmentation record table in the appendix M of GJB2425-95 conventional weapon warhead power test method, the maximum fragment natural fragment quality flight distance in each fragment quality classification interval is calculated respectively according to the personnel destruction criterion E of more than or equal to 98J, and the fragment quality of a killer is preferably controlled within 5 g-10 g. Table 1 thus lists the maximum fly-away distance of the fragments for different placement conditions with a fragment mass of 10 g.
Table 1: the maximum flying distance of the fragments under different arrangement conditions when the fragment mass is 10g
As can be seen from the equations 1 to 5, in an ideal state, the larger the fragment mass, the longer the fragment scattering distance. Therefore, the maximum fragment mass calculation formulas 1 to 6 of the projectile are introduced, the maximum fragment mass of the four projectiles used for calculation is determined, and the fragment flying distance is calculated, and the calculation result is shown in table 2.
In formulas 1 to 6, mmThe maximum mass of the fragments; m is the shell mass of the projectile; n is a radical of0The number of the broken pills is.
N in formulas 1 to 60The calculation formula of the broken pill quantity is
In equations 1 to 7
The calculation formula of (2) is as follows:
in the formulas 1-8, K is the coefficient of explosive and takes 4.5, QUOTE
；t0: the thickness of the elastomer wall; diThe inner diameter of the projectile.
Table 2: theoretically calculating the maximum mass of the fragments and the flying distance of the fragments of 200g
The utility model discloses a blasting tower explodes and destroys the processing, and landfill soil, hole wall can weaken the fragment around the projectile body and scatter and the shock wave propagation effect. In view of the above, the present study mainly determines the reasonable radius X of the dangerous area by analysis and calculation, and thus sets the optimal personnel safety distance Rdf。
From table 1, it is known that: the utility model discloses when this detonating tower fried the operation, in four kinds of bullet types that are used for the calculation, destroy the worker's size for length x wide x high (25 x 30) m time, the flying apart distance of 155 millimeters explosive bomb 10g nature rupture of pieces reaches 59.3m farthest.
From table 2 it follows that: when the blasting operation is performed on the blasting tower, if the size of the destruction work in four types of bullets used for calculation is (25 × 25 × 30) m, the maximum mass natural fragments of the 155 mm blasting bullet scatter at a distance of 353.2m at the maximum.
Considering comprehensively that the maximum number of fragments of 5 g-10 g in the process of forming the natural fragments of the projectile body can be formed, fragments with large mass can be formed, but the relative number is small, the shape of the fragments with large mass is irregular, the windward resistance is large, and the speed is attenuated, therefore, when the dangerous radius X is determined by the research, the farthest flying distance of the natural fragments of 10g of the projectile with 155 mm of the calculation result in Table 1 reaches 59.3m as the farthest flying distance of the fragments, so the radius of the dangerous area is as follows: x =59.3-20=39.3 m.
Consider when the utility model discloses the detonating tower explodes, landfill soil, hole wall can weaken fragment distance that flies apart around the shot, and the shock wave reflection in the hole also can be disturbed the flight orbit of fragment, nevertheless does not get rid of the possibility that individual big fragment falls outside dangerous radius area, considers certain factor of safety (k = 2), consequently, prevents that fragment from flying apart and hurts people's safe distance RdfPreferably, = k × X =78.6m ≈ 80 m. The 30-meter deep detonating tower designed according to the terrain can be well suitable for the destruction work of the scrapped ammunition.
The formula of the safety distance of the explosion shock wave to personnel is
In equations 1-9: w is the TNT explosive quality.
If the destruction amount is within 50kgTNT, the safety distance of the shock wave to personnel is as follows: rK=92.1m。
Therefore, the safety of personnel can be ensured by destroying operators and field commanders in the protective shield which is 80m away from the mouth of the detonating tower. The safety distance is considered without considering the catching net, and the designed catching net can further improve the safety of the destroying operation.
