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

Abstract

The invention discloses a connection effect target device suitable for measurement of target shock wave pressure of a movable explosion field. The effect target device is mainly characterized by beingcomposed 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 three working areas, with different pressure measurement ranges, on the response membrane after passing through pressure guiding holes, the maximal deflection value of the response membrane is measured after testing, and the pressure peak of the shock waves is obtained according to a dose-effect relationship of deformation of the membrane and the shock waves. The device has the significant advantages that the mass and size of aneffect target are greatly reduced, and movement, assembly and disassembly of the effect target in the movable explosion field are facilitated; circular structures are adopted for all parts of the effect target device, and the processing period can be shortened; on the condition that the size and mass of the effect target are reduced, the wide effective measuring range is guaranteed, a shock wavepressure range within which the target can be damaged is basically covered, and the requirement of the target of the movable explosion field for the measurement of 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 conjoined effect target device suitable for shock wave pressure measurement 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 damag...

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, but because the effect target device has a large range of pressure measurement and a wide working area, and The design and material selection need to be improved, so the mass (9kg) and volume of the effect target device are large, it is inconvenient to take, assemble and disassemble, and the on-site operation is time-consuming and laborious

[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. , The urgent need for effector targets in heavy-duty test tasks
