Calibration and Characterization of the WL/MNMF VHG Tester.

Abstract

The WL/MNMF constructed a very high acceleration (vhg) tester to be used in testing a whole fuze or fuze components under a controlled severe shock environment. This document present the calibration and the characterization of the vhg tester which were conducted to evaluate the range of application and to quantify the performance of the tester. The calibration defined as the peak acceleration generated as a function of the operating pressure is presented for different payloads. A 100 kg peak acceleration can be achieved even for the largest (10 lb) payload. The introduction of a cardboard mitigator between the piston and the anvil is shown to act as a 20 kHz low-pass mechanical filter. Frequency analysis is used to determine to which extent the vhg tester reproduce shock similar to those encountered in hard target penetration by a kinetic energy penetrator. It is shown that the tester can simulate the hard target penetration environment for the frequency range exceeding 25 kHz.
