The Application of Magnetorheological Damper in Machining the Impeller Blades of High Temperature Alloy

Abstract:

In this paper, it is described the vibration problems in machining the impeller blades of high temperature alloy and some Solution about Vibration Problems at present.Then in allusion to vibration and low efficiency in machining the impeller blades of high temperature alloy, a new and stiffness adjustable damper is designed according to extrusion mode. And we compose the performance of magnetorheological elastomers and the operating mode of magnetorheological elastomers. Then we experiment on the damper which we have designed using the test systems which has been erected. The experiments show that we can suppress the vibration through changing the current. And when the coil windings of magnetorheological elastomer damper are set as current, the stiffness of magnetorheological elastomer damper is adjusted and the vibration is suppressed. Therefore,we can suppress the vibration through changing the current. And the magnetorheological damper can meet the design requirements.
