Dependence of Hydraulic Fluid Added Mass in Hydromounts Throttle Channels on Controlling Magnetic Field

Abstract

The method of finding added mass of hydraulic magnetorheological fluid (MRF) in choking channels of magnetorheological transformer (MRT) of hydraulic vibration mount (hydromount) considering controlling magnetic field is presented in the article. Calculation of MRF added mass of Fluid MRF-132DG mark developed by LORD (USA) is given, filling the hydromount with MRT designed for damping impact loads. Hydromount with MRT has two controlled inductive slit choking channels in which MRF is excited by external magnetic field. MRF added mass unaffected by magnetic field was considered in this article.
