Chapter 5 Vibrations - Brown University

Chapter 5 Vibrations Overview of Vibrations Examples of practical vibration problems vibration is a continuous cyclic motion of a structure or a component. Generally, engineers try to avoid Vibrations , because Vibrations have a number of unpleasant effects: Cyclic motion implies cyclic forces. Cyclic forces are very damaging to materials. Even modest levels of vibration can cause extreme discomfort; Vibrations generally lead to a loss of precision in controlling machinery. Examples where vibration suppression is an issue include: Structural Vibrations . Most buildings are mounted on top of special rubber pads , which are intended to isolate the building from ground Vibrations .
