Determination of the Dynamic Rigidity of Magnetic Controllable Hydromount Dependence on the Frequency of Vibration

Abstract

Building damping characteristic of magnetocontrollable hydromounts and their correlational relationship with dynamic rigidity is considered in this article. Damping characteristics of hydromounts primarily comprise their amplitude-frequency characteristics (AFC). Building damping characteristics of magnetocontrollable hydromounts unaffected by magnetic field was performed basing on vibration tests data on vibrostand Star28, generating broadband random vibration (Random), in order to determine their resonance frequencies at 50 m/s2 input root-mean-square vibration acceleration (RMS).
