Abstract
In this paper; the dynamic characteristics of a semi-active magnetorheological fluid (MRF) engine mount are studied. To do so, the performance of the
MRF engine mount is experimentally examined in higher frequencies (50~170
Hz) and the various amplitudes (0.01 ~ 0.2 mm). In such an examination, an
MRF engine mount along with its magnetically biased is fabricated and successfully
measured. In addition, the natural frequencies of the system are obtained by standard
hammer modal test. For modelling the behavior of the system, a mass-spring-damper
model with tuned PID coefficients based on Pessen integral of absolute error method
is used. The parameters of such a model including mass, damping ratio, and stiffness
are identified with the help of experimental modal tests and the recursive least square
method (RLS). It is shown that using PID controller leads to reducing the vibration
transmissibility in the resonance frequency (=93.45 Hz) with respect to the typical
passive engine mount by a factor of 58%. The average of the vibration transmissibility decreasing is also 43% within frequency bandwidth (50~170 Hz).
