Beneficial effects of the present invention are：
1st, the present invention is provided with several target sheets in casing, can estimate trajectory road according to the quantity and position of shell hole on target sheet
Footpath, so as to estimate the actual Penetration Depth of body.
2nd, because the quality of target sheet is softer, when filling granular media, target sheet can cause to become because of both sides unbalance stress
Slot in shape, the present invention can set backplate provided with three slotted eyes in the both sides of target sheet, so can when filling granular media
Ensure that target sheet will not be deformed, so as to ensure that target sheet injects direction perpendicular to bullet, make final measurement result more accurate.
3rd, the present invention is arranged in equal spacing with tinfoil paper target sheet in granular media perpendicular to the incident axial direction of Rigid Projectiles, and in target sheet
Upper connection NLG202G-2 type multichannel tachymeters, when body passes through tinfoil paper target sheet, passage is connected and timing, by recording body
By the time for determining position, so that it may calculate its average speed between each adjacent tinfoil paper target sheet.
4th, casing sectional of the invention is assembled, so conveniently can transport and assemble, be used while emptying granular media
The quick sand leakage of bottom sand outlet, improves test efficiency.
5th, bottom half of the present invention is provided with adjustable support, the site condition strong adaptability limited to field, and on support
With sand swash plate is led, facilitate the gathering of granular media, improve test efficiency.
