Cook-off test device for testing reaction level of slapper detonator with regard to high-temperature stimulation

Abstract

The invention discloses a cook-off test device for testing the reaction level of a slapper detonator with regard to high-temperature stimulation. The cook-off test device is used for carrying out a cook-off test on the slapper detonator, and comprises an electric heating ring, a barrel body, a barrel cover, a test support and a witness plate used for bearing an impact of the slapper detonator after burst during the test, wherein the electric heating ring is installed outside the barrel body in a sleeving manner and used for heating the barrel body; the test support is installed in the barrel body; the barrel cover is installed at one end of the barrel body; the slapper detonator and the witness plate are installed on the test support respectively; and the witness plate is located between the slapper detonator and the barrel cover. The cook-off test device disclosed by the invention is convenient for adjusting the power of the electric heating ring to control the temperature rising rate of air in the barrel body through heating of the electric heating ring, thus controlling the temperature rising rate of the slapper detonator on the test support in the barrel body; and the reaction level of the detonator is calculated through the degree of destroy of scattering fragments of a shell of the slapper detonator on the witness plate when the slapper detonator reacts with regard to the high-temperature stimulation.

Description

technical field [0001] The invention relates to an experimental device for testing the reaction level of a shock-sheet detonator to high-temperature stimulation, in particular to a heat-baking experimental device for testing the reaction level of a shock-sheet detonator to high-temperature stimulation. Background technique [0002] The shock plate detonator is a detonator with high safety and reliability because of its strong resistance to mechanical shock, static electricity, stray current, radio frequency, etc. It is currently widely used in advanced insensitive ammunition. Thermal safety is an important research content of the safety of insensitive ammunition. The hot-baking experiment is the main method to study the thermal safety of ammunition. The known hot-baking experiments usually only study the response characteristics of explosives in ammunition under external thermal stimulation, ignoring the characteristics of ammunition.

Thermal safety is an important research content of the safety of insensitive ammunition. The hot-baking experiment is the main method to study the thermal safety of ammunition. The known hot-baking experiments usually only study the response characteristics of explosives in ammunition under external thermal stimulation, ignoring the characteristics of ammunition. The reaction characteristics of the detonator in the ammunition under the external thermal stimulation, the detonator in the ammunition will also react to the thermal stimulation, and its reaction level will affect the thermal response characteristics of the explosive. Therefore, it is very important to study the response characteristics of the detonator in the ammunition under the external thermal stimulation. Necessary
