Abstract

The invention belongs to the field of experimental mechanics of energetic materials and relates a testing device for high-axial-overload test of the energetic materials. The testing device comprises afront shell cover and a powder shell, and the powder shell mainly comprises a data storage system mounting space, a connection thread, a displacement sensor mounting groove, a full-size powder loading and mounting space, strain foil mounting grooves and a wiring groove. The testing device realizes mechanical response data measurement of energetic material full-size powder loading in a gun-launched high-overload environment and has the advantage of saving of testing cost and time, high axial overload refers to 6000g-12000g, and further adaptability to a wider overload range can be realized byadoption of a high-overload-resistant sensor, adjustment of a sensor measuring range and increase of data storage system caching.

Description

technical field [0001] The invention relates to a test device for mechanical experiments, in particular to a test device for high axial overload testing of energetic materials, and belongs to the field of experimental mechanics of energetic materials. Background technique [0002] At the initial stage of the artillery-launched missile launch or when the penetrating projectile penetrates the ground, the energetic material will withstand an axial overload of up to tens of thousands of g (gravitational acceleration), which may cause safety problems. Universal material testing machines, hydraulic servo testing machines, separate Hopkinson pressure bars, drop weight test devices and other equipment are widely used at home and abroad to study the thermodynamic characteristics of small-sized samples of energetic materials, and use simulation methods to predict the dynamics of full-sized charges. Actual response, but there is a lack of comparison and verification of full-scale charg...
