doi:10.3901/JME.2016.08.029

Abstract

Abstract: The present work is about the dynamic model and the experimental testing of the magnetorheological fluid(MRF) mounts, especially at wide frequency. A squeeze MRF mounts is adopted, according to Bingham model, the react force of the mounts is divided to three parts which contains coulomb damping force, viscous damping force and elastic force. An advanced polynomial Bingham parameterization model is built by analysing the relationship between the frequency, magnetic field and the each part force. The applied current and the excitation frequency in this model as variable, nine variable parameters of the second order polynomial are found by testing different operating conditions. A verification test shows the reliability and the performance of the proposed model.

Key words: dynamic test, engine isolation, magnetorheological mounts, parametric modeling
