Single body effect target device suitable for measurement of target shock wave pressure of movable explosion field

Abstract

The invention discloses a single body effect target device suitable for measurement of target shock wave pressure of a movable explosion field. The effect target device is mainly characterized by being composed of a base, a response membrane, a pressing ring, a buffering pad, a bottom cover and pressing bolts; external shock waves act on the effect target device and a working area of the responsemembrane, so that the response membrane is plastically deformed and sunken towards a lower sealing hole, the maximal deflection value is measured, and the pressure peak of the shock waves is obtainedaccording to a dose-effect relationship of deformation of the membrane and the effect of the shock waves. The device has the significant advantages that the mass and size of the effect target device are greatly reduced, movement and disassembly are facilitated, the processing cost can be reduced at the same time, and the processing period can be shortened; the effect of fixing the response membrane is reinforced, the area where the response membrane is plastically deformed is controlled, and the measurement precision of the shock wave pressure is guaranteed on the condition that the mass of the device is reduced; a deflection testing unit interface is reserved for the response membrane, the upgradability of a shock wave pressure effect target of the movable explosion field is improved, andthe requirement of the target of the movable explosion field for the measurement of the shock wave pressure is met.

Description

technical field [0001] The invention belongs to the technical field of damage assessment, and mainly relates to a pressure effect target device, in particular to a single effect target device suitable for measuring the shock wave pressure of a target in a dynamic explosion field. Background technique [0002] Damage assessment is a process of comprehensively considering the power of weapons and ammunition, target vulnerability, projectile action environment and other factors, and comprehensively evaluating and evaluating the effectiveness / effect of ammunition on targets based on damage action laws and measured damage parameters. Shock wave is one of the important damage elements produced by explosion, and it is an important index to characterize the explosive power of ammunition. Target shock wave pressure, that is, the pressure load on the target structure during explosion, is the source of damage to the target structure and the basis for the evaluation of the target damage...

AI Technical Summary

Problems solved by technology

[0003] The engineering environment for the shock wave pressure measurement of the target in the dynamic explosion field is extremely harsh. Compared with the static explosion field, some targets are seriously deformed and even disintegrated. In this case, it is difficult for the pressure electrical measurement device to survive; There are many measurement points, sometimes hundreds of points, and the time is tight, the terrain is complex, it is difficult to use electrical measurement method to lay out, and the cost is high and unbearable

The invention patent "201711286128.9, an effect target device suitable for measuring the shock wave pressure of a target in a dynamic explosion field" largely solves the above problems. The design and material selection are debatable, so the mass (9kg) and volume of the effect target device are relatively large, and it is inconvenient to take, assemble and disassemble, and the on-site operation is time-consuming and laborious

Moreover, in the target shock wave pressure measurement of the dynamic explosion field, the shock wave pressure range of 0.09-1.5MPa is the most common, so for the shock wave pressure test determined as this range, it is not necessary to use the above-mentioned effect target device

[0004] The deficiencies and defects of the existing technology are: (1) The quality and volume of the effect target are large, it is very inconvenient to take, load and unload, and the on-site operation is time-consuming and laborious, and it is not safe; (2) The processing cycle is long, and it is difficult to meet some time constraints. 1. There is an urgent need for the effect target for heavy test tasks; (3) The effect target device does not reserve a response diaphragm deflection measurement interface, so it is difficult to upgrade the device
