Abstract
In a hydraulic drive control system,the structural design of traditional mechanical valves is complex and the volume is large.According to the superparamagnetism of ferrofluid,a novel hydraulic driver control method is presented based on the robot hydraulic drive control system.The magnetic field is directly added to the traditional hydraulic fluid modified by the ferrofluid,and the pressure of this hydraulic driver system achieves the dynamic deflection.A mathematical model of ferrofluid flowing in the air field under the magnetic field is established based on the Ferro Hydro Dynamics (FHD).A model of Eulerian is presented to describe the ferrofluid jetting in the air under different magnetic flux densities with the secondary development of the software Fluent.Numerical simulations are performed to obtain velocity distributions and the dispersion behavior.The result shows that when the outlet height is 30 mm,the offset of liquid flow is 1.1 mm under the magnetic field of 0.08 T.Then the correctness of the model is verified by experiments.In the new ferrofluid hydraulic drive system,the high-pressure liquid flow is excited by the magnetic field without moving parts.This method has the advantages of simple and compact structure,easy adjustment of applied excitation parameters and quick response.关键词
