Modeling and Characterizing of Electrodynamic Shaker ESE 211

Abstract

The Shaker actuator is a fundamental component in vibration testing and control systems, serving as a versatile tool for inducing controlled vibrations in mechanical structures. Knowing the characteristics performance is essential for selecting the right electrodynamic shaker for a specific testing application. This paper investigates performance parameters of electrodynamic shaker type ESE211 from VEB Schwingungtechink und Akustik, WIB, Dresden, for which there is no available performance data online. Using system identification techniques by measuring dynamic response and various electrical and mechanical parameters, we create an integrated electro mechanical mathematical model and simulation model in MATLAB/SIMULINK. Using this combined modeling technique, where part of the parameters are obtained with static measurements, and part with dynamic measurements, we create a model which gave an excellent result in comparison to the experimental results. The testing range of dynamical response of the shaker was from 1Hz to 100 Hz sinusoidal sweep input signaland payloads specimens from bare table to 975grams.
