Abstract:Attempting to suppress high frequency resonant vibrations of a hydraulic servo-valve torque motor, vibration characteristics of armature assembly in the torque motor with and without magnetic fluids are studied in this paper. The mathematical model of the resistance force that the magnetic fluids acts on the armature is established. The equivalent physical model of magnetic fluids which is taken as a spring and a damper, is studied according to the relationship between the resistance force and the squeezing di… Show more
