VIBRATION-BASED METHODS FOR EVALUATING LINEARITY OF DC-COUPLED VIBRATION ACCELEROMETERS

Jeffrey Dosch, Mark Schiefer

Abstract

This paper describes a shaker technique for measuring nonlinearity of accelerometers. The method has application to acceptance testing of DC-coupled accelerometers where the use of a centrifuge is cost prohibitive. To demonstrate the utility of shaker-based methods, nonlinearity tested by both centrifuge andshaker is compared.
