In-situ Capacitance Sensing for the Settlement of Magnetorheological Fluid: Simulation and Experiments

In light of the insurmountable sedimentation magnetorheological (MR) fluid, it is great significance to ensure performability an MR damper by introducing a sensing method for fluid settling, and key indicator identify health status critical. However, settling monitoring system can nowadays only function in laboratory with transparent non-magnetic tubes, which not qualified in-situ steel-made cylinder. Under analysis open plate capacitor (OPC) configuration, relationship between concentration capacitance investigated simulation experiments, based on OPC, settlement designed. Long-time carried out home-made fluids, test results show that effectively reflect settled has potential be utilized identification compression points, provides strategic signal probable active or operational re-dispersing fluid.
