Description
Technical field
The invention belongs to shock wave pressure field tests, relate generally to a kind of explosive field shock wave pressure measuring method, especially
It is related to a kind of effect target structure for measuring movable object shock wave pressure peak value and average peak load and test side
Method.
Background technology
Explosion wave superpressure is to weigh the Important Parameters of brisance, is also the key factor for causing target Damage, right
The measurement of superpressure can be using equivalent pressure tank method, equivalent target plate method, biological assays, electrical measuring method etc..Generally adopt both at home and abroad at present
With electrical measuring method, its advantage is that accuracy is high, can reflect whole change procedure, is easy to signal storage record, has the disadvantage easily to receive
Electric measuring system is acted on to factors such as interference, high temperature, HI high impact and electromagnetic environments, stronger ghost effect can be produced, it is right to need
It carries out dynamic compensation or amendment, and electrical measuring method wiring is numerous and diverse, relatively costly, and multi-measuring point is laid more in large-scale explosive field
Difficulty, almost cannot carry out particularly with some complex environments such as gully, hilly country.
When explosion wave is studied to vehicle, the damage effect of the similar target of container, generally want to obtain these typical cases
The shock wave pressure average load of target surface.And because pressure sensor pressure-sensitive face area is relative to target size very little, survey
The pressure for obtaining is only the pressure loading at the point, so as to need to arrange that more channel pressure sensor can just measure target plane
Well-distributed pressure load；In addition, in the presence of shock wave, these targets can occur large deformation and can knock several meters away very by shock wave
To tens meters, if using electrical measuring method measuring shock waves pressure loading, the transmission line of sensor has no idea to ensure intact at all, passes
Sensor is likely to be destroyed and is difficult with.Under this pressure measurement operating mode, electrical measuring method is substantially infeasible, not only may be used
Cannot ensure by property, workload it is big, and cost is very high.
In view of the shortcoming of electrical measuring method, can adopt effect target method of testing as another kind of approach for obtaining shock wave parameter.It
General rectangle or circular metal film using different-thickness, evaluates quick-fried according to the plastic deformation of Explosion Loading rear film
Fried power, during in particular by some light material (such as aluminium alloys), its deformation under varying strength Explosion Loading
Difference is obvious, and the repeatability of result is preferably, can be used as a kind of assembling means of testing simple, with low cost, it is to avoid existing electricity
Examining system loses the risk of data.Existing effect target diameter is larger, only monofilm measurement pressure, and precision is poor, and without that
Big calibrating installation calibrates the relation of its deformation and impact wave load；In addition major diameter effect target weight is larger, installs not side
Just；According to criterion is injured, major diameter effect target resonant frequency is relatively low, injures criterion for P-I criterions, it is impossible to only using P criterions
Or I criterions, can otherwise produce larger error.
In view of the above shortcoming of conventional effect target, the effect target is not used to measure removable target shock wave pressure and flat
Equal load.For the acquisition of movable object surface impacts wave load under shock, minor diameter diaphragm effect target without
It is suspected to be larger advantage.On the one hand, because diaphragm diameter is less, thickness is little, and resonant frequency is higher, can use P criterions (peak value pressure
Power criterion) deform criterion as it；Further, since diameter is little, can according to P criterions in shock tube to diaphragm deformation and shock wave
The relation of pressure is demarcated；The shock wave that measuring point on target in many pressure-sensitive diaphragm effect target measurement smaller ranges can be designed is average
Load, with higher precision；Little effect target is transported and easy for installation, and cost is relatively low, can be in the multiple positions in target pressure measurement surface
Install.To sum up analyze, a kind of little effect target structure can be used to measure the removable target shock wave pressure of explosive field and average load.
