A 2-DOF MODEL FOR BACK-TO-BACK SHOCK TRANSDUCER

Henrik Volkers, Thomas Bruns

Abstract

By applying a two-degree-of-freedom system model (2-DOF) for an Endevco type 2270 back-to-back reference accelerometer, systematic deviations between measured and fitted 1-DOF transfer functions could be improved. Some key information for the identification of the model parameters is found in the frequency range beyond the first resonance, a range which was rarely considered in the past.
