Method.
Background technology
The calibration that is carried out in national measurement department of shock wave test system is completed in standard laboratory, calibration it is sensitive
Degree can only represent the pressure under this kind of environment and the relationship between voltage.In the wild under working environment, shock wave tests system
Operating condition has sizable difference with laboratory.Since the sensitivity that shock wave tests system is influenced very by environmental factor
Greatly, while every time experimental condition cannot be identical, therefore in order to improve the precision of test system, needs before testing it
Field calibration.In demarcating at the scene, universal method is to generate shock wave as pressure source using high explosive, is impacted by measuring
At the time of wave reaches and the output signal of test system, and then the charge sensitivity of system is obtained.High explosive explosion time exists
Larger danger, test system are closely subject to destroy excessively, are unsatisfactory for the test request apart from 2 meters of shock wave source again too far.In addition, high
The preparation of energy explosive is comparatively laborious, and generated impact crest value is obtained by calculation.Although equivalent is the same, due to mixed
The uneven impact crest value that can cause explosion time different directions brought when conjunction has differences, even if the difference is little, but makees
It is calibration source using can seriously reduce stated accuracy, cannot be satisfied military mark at all through its calibrated test system and test precision
Alignment request.
