Study on Testing System of the Dynamic Primary Pressure for the Controllable Detonation of Unserviceable Ammunition

摘要

In the controllable detonation of unserviceable ammunition, the dynamic primary pressure of explosion has the characteristics of transient and single impulse. Just on the basis of the press-resistant and frequency response properties of manganin pressure-resistance sensor and the characteristics of its low temperature coefficient, a testing system of the dynamic primary pressure for the controllable detonation of unserviceable ammunition, which is mainly composed of manganin pressure-resistance sensor, is established. Begin with the brief introduction for the testing system, the article introduces the technological constitute of the testing system as to the work principle of the manganin pressure-resistance sensor, the selection for the sensors, invariable power supply and transient recorder. At last, the practical application is presented.
