An Effective Small Electrodynamic Shaker Modeling Method

Abstract Currently, the discussion on the modeling method characterized by the small electrodynamic shakers, especially the mathematic analytical method, is relatively sparse. In this paper, taking BK4809 as an example, a modeling method for small shakers based on analytical formulations is discussed. The detailed mathematical analysis and derivation process for the small shakers are performed, and the corresponding modeling formulations are concluded; then, the simulation tests are carried out in MATLAB. Through comparison with the reference data, the validation tests show that based on analytic formulations combined with the MATLAB built-in system identification functions, the results of modeling methods match well with the experiment data, and the concluded method is effective.
