V I B R A T I O N S L A B O R A T O R Y Operations Manual Eric Marsh Martin Trethewey Department of Mechanical and Nuclear Engineering Penn State University Version: Fall 2006
P R E F A C E This laboratory course provides an opportunity to apply the fundamental vibrations theory taught in ME 354 to actual mechanical hardware. The experiments have been designed to illustrate many of the fundamental concepts presented in ME 354, with many subtleties also apparent to the observant and inquisitive student. Please treat the equipment and facilities in this laboratory as if it were yours, because it is! All the equipment in this laboratory has been purchased with your tuition surcharge fees. The continued use and evolution of this laboratory is dependent on you. If you experience any equipment difficulties please alert the lab staff so it may be repaired. Comments and recommendations in regard to the lab operation and experiments are welcomed and encouraged. This manual is not designed to be completely self-contained, but does present the essential information you will require while performing the experiments. The manual will review the fundamental theory and present an overview of each experiment. During your preparation for the lab, you should review supplemental background material from your personal library and course notes. A conscious effort has been made not to make the instructions too cookbook in nature, since this tends to limit your curiosity and exploration of the equipment and testing procedures. During the course of the semester you may become frustrated at times when either the equipment does not function as you expect or your data makes little logical sense. Remember that even the most experienced experimentalist also encounters these situations often. Finally when all the pieces of the puzzle are fit together you can see that actual mechanical systems do behave as the fundamental theory predicts. Welcome to the exciting and rapidly changing world of experimental vibration analysis.
