    Abstract

    A systematic Finite Element design and optimisation procedure is implemented for the development of piezoelectric accelerometers. Most of the specifications of accelerometers can be obtained using the Finite Element simulations. The deviations between the simulated and calibrated sensitivities and resonance are proved to be within 8%. The computerised design and optimisation makes it possible to minimise the development time and cost to a maximum extent. As examples, the Finite Element simulations for standard Brüel & Kjær OrthoShear accelerometer 4506 and ThetaShear accelerometer 4507 are given.
