Abstract

The invention discloses a multi-parameter measurement system and method for a fragile type armor-piercing projectile dynamic target experiment fragment, and belongs to the technical field of fragile type armor-piercing projectile dynamic target experiment fragment parameter measurement. The measurement system includes a ballistic gun for firing a fragile type armor-piercing projectile, an armoredsteel plate, an experimental target, a speed measurement module which measures the speed of the fragile type armor-piercing projectile, a pulsed laser module which emits laser towards the fragment, aCCD camera group for recording holograms of the fragment at different moments, a timing control module and a calculation module. The fragile type armor-piercing projectile hits the armored steel plateto form the fragment. The timing control module is used for receiving a voltage signal of the speed measurement module and sending out a pulsed laser light-emitting voltage signal and a CCD camera exposure-starting voltage signal according to preset timing. The calculation module is used for collecting the holograms of the fragment recorded by CCD cameras and reconstructing software by using theholograms to obtain the size, shape, three-dimensional speed and acceleration parameters of the fragment. The size, shape, three-dimensional speed and acceleration parameter information of the fragment can be obtained.

Description

technical field [0001] The invention relates to the technical field of fragment parameter measurement for a dynamic target experiment of a fragile armor-piercing projectile, in particular to a multi-parameter measurement system and method for a dynamic target experiment fragment of a fragile armor-piercing projectile. Background technique [0002] With the rapid development of armor defense technology, anti-armor weapons emerged as the times require. Fragile armor-piercing ammunition is a new type of ammunition with the characteristics of armor-piercing ammunition and grenade. The core material of this ammunition can not only penetrate the protective armor of the tank like conventional armor-piercing ammunition, but also after the ammunition penetrates the armor and enters the interior of the target, under the action of the shock wave It is broken down into a large number of high-speed fragments to cause an effective secondary strike on the target behind the armor, achieving...
