Abstract
It was presented that adds a magnetorheological fluid squeeze film damper on the wheel spindle of ultrahigh speed grinder as a assistant elastic sustain, to attenuate the vibration of the wheel spindle and realize semi-active control to it. Work principle of magnetorheological fluid squeeze film damper was study and the simulation analysis of the wheel spindle motion was done. Base on the theory research the damper was designed and experiments was done. Experimental result show the vibration causing by the unbalance weight of wheel spindle can be attenuated effectively by adding a magnetorheological fluid squeeze film damper on it. At the same the finishing quality of workpieces can be improved 10%~20%, and the work efficiency of the machine can be raised 15%~25%. Research works provides a new method for wheel spindle design of the ultrahigh speed grinder.
