ABSTRACT
This paper presents a simple dynamic identification technique using Fast Fourier Transform (FFT) and least-square method to respectively estimate the system frequency and damping coefficient together with Coulomb or static friction of Magneto-Rheological (MR) device-plane frame system. This proposed technique was aimed to handle the presence of Coulomb or static friction in the system, which was not commonly be addressed by the available system identification methods. Validations between simulations and experimental results were performed to verify the performance of the characterized system dynamic properties prior use for dynamic simulations. Results showed that the free vibration responses of simulation models computed using the identified dynamic properties were in good agreement with the experimental results.
