Embodiment Construction
[0036] see figure 1 , place the explosive grain column 2 on the test site, and leave the detonation position 1 set for the test, use two high-speed scanning cameras to align the waveform of the section of the explosive to be studied, and adjust the slits of the two cameras to make the slits The slits are perpendicular to each other, and the detonation waveform of the explosive is observed.
[0037] For specific tests, follow the steps below:
[0038] The test explosive sample is made into a cylindrical powder column 2 of required specifications, the explosive column 2 is left with a position for installing the detonation position 1, and the explosive column 2 is stored in the explosive temporary storage area;
[0039] Measure the resistance of the detonator, place the measured detonator in the temporary storage area of the detonator, and keep the lead wire of the detonator short-circuited during the temporary storage;
[0040] Arrange the test site, check and debug the hi...

The invention discloses a grid-type detonation waveform scanning test method, which solves the problem that the prior art method cannot quantitatively evaluate the variation law of the detonation wave propagation speed, direction and waveform of explosives under eccentric detonation. The method of the present invention adopts two mirror-rotating high-speed cameras to simultaneously perform multi-slit scanning on the cross-section of the charge to be studied in two mutually perpendicular directions, thereby recording its detonation process in an eccentric detonation mode. Interpretation and data processing can obtain the propagation characteristics and waveform variation law of detonation wave in two vertical directions, so as to quantitatively evaluate the detonation wave propagation velocity, direction, and waveform variation law of explosives under eccentric detonation. The method of the invention is mainly applied in the field of charge optimization design and damage capability estimation of eccentric detonation warhead.
Description
technical field [0001] The invention relates to a detonation waveform scanning test method, which is mainly applied in the field of charge optimization design and damage capability estimation of eccentric detonation warhead. Background technique [0002] As a new type of high-efficiency damage warhead technology, the eccentric detonation warhead has the characteristics of high energy utilization rate, high damage power, and easy engineering. Fragment density and fragment velocity. Quantitative evaluation of the propagation velocity and direction of the detonation wave, and the variation of the waveform is the key to increasing the fragment density and velocity in the target direction, and it is also an important way to improve the damage capability of the warhead. [0003] In the eccentric detonation warhead, there is no unified evaluation method and standard for judging the propagation speed and direction of the detonation wave in China, "Detonation Wave Characteristics of...
