Abstract
A realistic study of high-cycle fatigue in turbo-machinery is dependent on a means of reproducing, in an evacuated test facility, the vibration of turbine blades caused by inhomogeneous flow in the engine. An apparatus and method are described which use magnetic eddy currents to generate such vibration. The apparatus makes use of an array of magnets to produce blade vibration of the magnitude and period characteristic for turbo-machines.
