Problems solved by technology

[0005] In the dynamic explosion field, the impact point is uncertain, and the shock wave pressure of the target varies greatly. The effective range of the existing effect target is small, and cannot cover the entire pressure range that can effectively damage the target; The acting direction of the shock wave pressure is uncertain, so the rear end of the effect target must be sealed to prevent the interf

Abstract

The invention discloses an effect target device for shock wave pressure measurement of a target of a moving explosive field. The effect target device is characterized by comprising a base, an intermediate body, a response diaphragm, a cover plate, a sealing hole, a pressure leading hole, compression bolt holes, compression bolts, an auxiliary hole, and an auxiliary plate. When an external shock wave is applied to the effect target device, the wave is applied to five working areas of the response diaphragm through the pressure leading hole of the cover plate to cause plastic deformation and recession into the sealing hole below; a maximum deflection value is measured; and according to a dose-effect relationship between diaphragm deformation and an impact shock effect, an impact wave pressure peak value is obtained. According to the invention, the effect target device has the following advantages: the effect target device with the light weight is easy to arrange; the sealing performanceis good; the interference of the shock wave diffraction is eliminated; the effective range is wide; the pressure range capable of damaging the target is covered basically; a measurement problem of a large shock wave pressure changing range of the target of the moving explosive field is solved; the precision and reliability of the target pressure measurement in the moving explosive field are improved; and the need of the shock wave pressure measurement of the target of the moving explosive field 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 an effect target device suitable for target shock wave pressure measurement. Background technique [0002] Damage assessment is a process of comprehensively considering the power of weapons and ammunition, target vulnerability, projectile interaction environment and other factors, and comprehensively estimating and evaluating the effectiveness / effect of ammunition on targets based on the law of damage action and damage data. 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 effect. [0003] In the past, a lot of resea...
