　　Blade-casing rubbing can occur under the small blade-tip clearance,which may lead to the rubbing damage,excessive vibration of whole unit,and efficiency loss caused by the increasing tip leakage flow.In most cases,only acceleration signals from the casing can be picked up,and it is difficult to obtain the vibration displacement data in actual aero-engine.
