An Explosive Stress Test Device Based on Multiple Pulse Tests

Abstract

The invention discloses an explosive stress testing device based on multiple pulse tests. In the device, the upper pressing plate is a circular platform body, and the central part is a stepped through hole; along the stepped through hole of the upper pressing plate, stepping columns are sequentially installed from top to bottom. , manganese-copper sensor, data transmission line and lower base plate, the platform-shaped column is a stepped cylinder, the end with a smaller diameter is connected to the sleeve and the sample in the test bomb, and the end with a larger diameter is connected to the through hole with a larger diameter on the upper pressure plate One end of the manganese-copper sensor coincides with the center of the lower base plate; the lower base plate is a circular platform, and grooves are arranged on the end surface in contact with the upper platen, and the lower base plate is connected with the upper platen through a platform-shaped through hole. The invention reduces the number of experimental devices and test device components for multiple pulse tests, fixes the positions of the test bombs and test devices, and avoids the failure of the test parts to damage the connecting wires in advance due to vibration and other reasons during the impact process or the test parts are separated from the sensor and cannot obtain data. This phenomenon improves the test success rate and data accuracy.

Description

technical field [0001] The invention belongs to the field of explosive charge performance parameter testing, relates to an explosive charge stress test device, in particular to an explosive charge stress test device suitable for multiple pulse tests. Background technique [0002] When the penetrating warhead penetrates the multi-layer target, the internal explosive charge is subjected to multiple pulse loads. Under the periodic action of multiple pulse loads, the explosive charge may appear cracks, breakage and other phenomena, or even ignite. Multiple pulse tests can be used to study and evaluate the safety of explosive charges under multiple pulse loads. [0003] At present, single pulse is mostly used in the field of explosive safety assessment in China, and two or even multiple pulse tests are rarely used. Qu Kepen et al. In April, ZL2015 1 0697886.4), two pulses can be realized in this patent, but the test components (sensors) are not described in detail. (Measuring a...
