Abstract

This manuscript describes a novel concept of triaxial shock measurement system with three combined laser Doppler vibrometers and Hopkinson bar. This system measures three-dimensional acceleration at one point for evaluating frequency response (sensitivity and phase shift) of triaxial accelerometers. At the conference, the experimental results will be presented.
