Abstract

A measurement chain dedicated to impulsive vibration is designed and tested to measure acceleration and force on the butt of a gun. The gun is the standard ordnance side weapon of the NATO Treaty and the bore is 9 mm. VPA on single and three shots were evaluated and the crest factor and the root mean square value of the weighted acceleration were computed. Power and energy absorbed, acceleration, and crest factor values, were computed. The higher standard deviation of the crest factor is found to be due to the variability of different subjects holding the gun. The results also show that higher force values tend to increase the crest factor, while they reduce the r.m.s. value. Gunshot absorbed power has a rather high value, if compared with other working activity involving vibration exposure. The absorbed power is found to be insensitive to increasing force because it is uncorrelated to the r.m.s. value.
