Abstract

The invention provides a test observation method for an electric explosion and energetic material synergistic explosion effect. The test observation method comprises the following steps: connecting a metal wire and an energetic material capsule between an upper discharge electrode and a lower discharge electrode; arranging an electrical parameter measuring unit; building and debugging an optical observation unit; controlling the trigger time sequence of the high-speed framing camera, the laser and the discharge trigger through a delayer, and setting the trigger delay; setting charging/discharging parameters of an energy storage capacitor according to the to-be-fed electric energy, and debugging an oscilloscope and setting to be in a to-be-triggered state; connecting a circuit; filling nitrogen into the explosion cavity; pressing a trigger button of the discharge trigger to form a synergistic explosion effect; calculating and analyzing an electrical parameter measurement result; and processing and analyzing framing image data. According to the invention, the circuit conduction time is prolonged, the energy fed into the energetic material is increased, the output energy reaches three times of the TNT equivalent, and the synergistic explosion of the electrical explosion and the energetic material is realized.

Description

technical field [0001] The invention belongs to the field of explosion and damage, and relates to an explosion effect test, in particular to an experimental observation method for the synergistic explosion effect of an electric explosion and an energetic material. Background technique [0002] The electric energy is fed into the chemical explosion reaction of the energetic material through the electric explosion of the metal wire, so that the energy of the two is coupled with each other to produce a synergistic explosion effect, which can realize the large equivalent energy output capability, simulate the explosion effect of new high-energy materials, and study its explosion effect. Intrinsic laws will help to rationally use the explosion effect of new high-energy materials in the future to achieve efficient damage to targets by weapons. [0003] On the one hand, the existing method of using wire electric explosion to drive energetic simple substances and mixtures (for examp...
