Design of controllable flexible bearing based on magnetic fluid damping
Abstract：The damping controllable flexible bearing of the magnetic fluid is a new type of shock absorber, and the main magnetic fluid is the magnetic fluid as the medium，The magnetic fluid damper has the characteristics of fast response, convenient control， small size, compact structure, easy connection with computer and damping force．In view of the magnetic fluid shock absorber is a new type of intelligent actuator, it has wide application and broad prospect, so it is very important to design a good magnetic damper with good performance． For this purpose，the author hopes that the structure of the magnetic fluid damper can be changed by simulation and experiment to improve the performance of the magnetic fluid damper．
Firstly, according to the characteristics of MR fluid and considering the design experience of the economy and other scholars, the damping controllable flexible bearing is designed．This paper on the design of magnetic fluid controllable damping of flexible bearings are software ANSYS simulation of the internal magnetic field．Simulation results show that the reasonable design of the magnetic fluid damping controllable flexible bearing structure, basically meet the design requirements. In order to study the influence of the gap to the damping force, a system of the performance measurement of the shock absorber is built. The relationship between the clearance and damping force of the controllable flexible bearing is studied by the test system．Through the research of this paper, the influence of the gap on the damping force of the controllable damping force of the damping of the magnetic fluid is verified．
Key words：damping controllable flexible bearing； Ansys； testing system；clearance．
