The peak overpressure and impulse of the air shock wave generated when the explosive explodes in the air is an important parameter of the explosive's energy characteristics, and it is also an important indicator to measure the damage effect of ammunition, especially blasting and killing-blasting warhead. Significance. The overpressure test test device is generally shown in the figure:
The sensor receives the pressure signal generated by the explosion, and after it is digitized by the data collector through the signal adapter (amplifier), it is recorded and analyzed.
As the main provider of domestic data acquisition equipment, we assisted multiple units to complete the free field explosion shock wave pressure test, familiarized with how to deal with the problems in the field test, understand the problems of the existing test system, and are responsible for the establishment of a new set of Test system, presided over the completion of the test experiment, and got more ideal test data.
The common overpressure test currently consists of the following parts:
Sensors: In overpressure testing, piezoelectric signals and piezoresistive sensors are generally used for pressure signal testing.
Signal adapter: Piezo sensor needs to be equipped with charge amplifier. Piezoresistive sensors need to be equipped with data amplifiers or dynamic strain gauges.
Data acquisition and processing system: At present, there are two methods of data acquisition equipment: general-purpose dynamic test analyzer, remote data collector for field use.
