Estimation of electrodynamic exciter parameters by means of circle-fit method
Original language description
The electrodynamic inertial exciter is an electromechanical transducer extensively implemented in a number of technical applications. The exciter commonly operates in a wide frequency range and its performance strongly depends on the input excitation parameters and output loading. The identification of basic transducer parameters is thus necessary for the design and development of electromechanical devices or for modelling and simulation of exciter frequency response using a lumped-element model. The paper introduces an experimental and calculation method for electrodynamic exciter parameters estimation based on the circle-fit of measured frequency response functions, an approach common in a classic experimental modal analysis. The method is suitable for simple electromechanical or electroacoustic systems whose natural frequency falls within the operational frequency range. The procedure was verified on displacement to current and voltage to current transfer functions measured on a commercial electrodynamic exciter.
