A two-chamber quasi-airtight container experimental device

Abstract

The invention discloses a two-cabin type quasi closed container experiment device, which is mainly applied to the measurement of multifunctional energetic material impact energy release. The device comprises a front hemispheric shell, a first cylindrical ring, an annular cover plate, a front window, a front sensor mounting hole, a target plate fixed ring, a target plate, a rear hemispheric shell,a rear sensor mounting hole, a rear window, a second cylindrical ring, a third cylindrical ring, a front protective wind cap and a rear protective wind cap. The initial speed of a test sample is obtained through the loading modes such as a ballistic rifle and a light-gas gun, the test sample enters a container after penetrating through a thin iron plate, the target plate in the middle of the container is struck to perform a chemical reaction, and generated energy cause that the air pressure inside the container is increased. The pressure change is captured by using a sensor, and then the energy release level of the sample is balanced. The device has the advantage that the excess pressure values before and after the target are measured by a front hemispheric container and a rear hemisphericcontainer respectively, and time difference of data of the respective hemispheric containers does not exist in theory. The protective wind caps can preferably protect the sensor from being damaged bybroken plates.

Description

technical field

[0001] The invention belongs to the research field of impact energy release of materials, and in particular relates to a two-chamber quasi-airtight container experimental device. Background technique

[0002] Chemical reaction and energy release under impact conditions are important properties of multifunctional energetic materials. Therefore, it is very important to design corresponding experimental devices to measure the energy release levels of various active metals with different formulations under different impact conditions. The formulation design of functional energetic materials provides data support. At present, the most commonly used test method for this kind of experiment is the airtight container experimental device designed by AMES. The device is generally cylindrical, the target plate is located in the middle of the cylinder, and the front end is a thin iron plate. The test sample obtains initial velocity through loading methods such as ballist...
