New equipment for producing and following the fatigue process, in metals, has been developed. The specimens, which must be in the shape of tuning forks, are resonated at high amplitudes. This is achieved by attaching small, powerful, samarium-cobalt magnets to the ends of the tynes, enabling them to be driven efficiently by a "U"-core electromagnet. A small, piezoceramic strain gauge provides a method of picking up the vibrations. To maintain resonance, the signal is used in a positive feedback loop, which incorporates an analogue multiplier to provide AGC. This also keeps the amplitude constant at any desired level, throughout the duration of an experiment. 2014-10-11T12:00:56Z 2014-10-11T12:00:56Z 1988 Master Thesis Masters MSc http://hdl.handle.net/11427/8324 eng application/pdf Department of Electrical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
