Overview

NISTIR 7724: A Next Generation Electrodynamic Shaker for the Primary Calibration of Acceelerometers by U.S. Department of Commerce

A new shaker system was designed to allow direct primary calibration of accelerometers using both reciprocity and interferometer techniques over the frequency range 40 Hz to 10,000 Hz. The system uses dual magnets and a dualcoil moving element. The design uses damped flexures to support the moving element. The dual-coil feature eliminates the need for an additional shaker for reciprocity calibrations. To accommodate improved comparison calibrations, the moving element is compact in design and is equipped with axially-oriented mounting tables at each end. Provision of easy laser interferometer beam access to both ends of the moving element allows interferometric accelerometer calibrations.
