Testing device and method for material dynamic response testing under high axial overload

Abstract

The invention discloses a testing device and method for material dynamic response testing under high axial overload, relates to a testing device and method for material dynamic response testing underhigh axial overload, and belongs to the field of material experiment mechanics under the high axial overload. The testing device comprises a testing bullet, artillery and a recycling device; the testing bullet comprises a testing device body for high axial overload testing of a material, a transformed standard bullet shell and a tested material full-size charge; the artillery is used for horizontally shooting the testing bullet to provide a shooting high axial overload environment; the recycling device is used for decelerating and recycling the testing bullet within the limited distance on thepremise that it is guaranteed that the structure of the testing bullet is complete, and testing data recycling is achieved; and the recycling device serves as a shooting target of the artillery. According to the testing device and method for material dynamic response testing under the high axial overload, recurrence of the shooting high axial overload environment is achieved, and effective testing data recycling is achieved.

Description

technical field [0001] The invention relates to a test device and method, in particular to a test device and method for dynamic response testing of energetic materials under high axial overload, and belongs to the field of material experimental mechanics under high axial overload. Background technique [0002] Gun-launched missiles, terminal-guided projectiles, and other weapons that use solid rocket motors to boost or increase speed, in the initial stage of launch, under the action of the internal pressure of the artillery, the charge of energetic materials in the projectile will withstand a short-term (10ms ~20ms) high axial overload may cause safety problems. Therefore, it is necessary to measure the dynamic mechanical response of materials under high axial overload. [0003] For the measurement of the deformation and response of energetic material charges within milliseconds under the high axial overload test environment of tens of thousands of g, there is currently no ...
