The experimental provision answered is used to measure the active metal of various different formulations releasing under the conditions of different shocks can be horizontal extremely important,
It can be designed for the formula of multi-functional energetic material and data support is provided.At present the most common test method of this experiment be by
The closed container experimental provision of AMES design, the device are generally tubular, and target plate is in the middle part of cylinder, and front end is sheet iron.
Test sample obtains initial velocity by loading methods such as ballistic rifle, light-gas guns, enters inside container after penetrating the tagger in front, hits
For the target plate hit in the middle part of container to chemically react, the energy for chemically reacting generation causes the air pressure inside container to increase.Position
In container different parts sensor by not air pressure change in capturing vessel, so that measuring releasing for the sample can be horizontal.However
The shortcomings that this experimental provision, there are two aspects: 1, it reacts after material hits target plate, energy is in a manner of spherical wave
It propagates outward, and container is generally tubular, the time for reaching container different location so as to cause reaction energy is different.Lead to difference
The waveform that the sensor of position measures has the time difference.2, target plate is located in the middle part of cylinder, and space communicates after target front target, if target plate quilt
Puncture, can be collided in cylinder before target with the variation of superpressure caused by the energy after target, to cause measurement inaccuracy；If target plate
Not puncturing, reaction energy needs to propagate to the vessel space after target around target plate, when the energy of reactant release is lower, energy
Amount has different readings around decaying after target plate, so as to cause the sensor before target and after target.It is difficult to accurately calculate and releases energy
Energy value.
