| Abstract: | A method to eliminate the effects of a transducer mass on modal parameters in modal tests is presented. The method is suitable for the usual experimental case-fixing exciting point/ moving single transducer. It does not change the experimental setup or increase the amount of measurements. The effects of the transducer mass are eliminated by an analytic routine. Simulation and experimental study on a beam prove that the method is correct and efficient. |
