Vibrations . 5.1 Overview of Vibrations . 5.1.1 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.

The concept of damping is also very important in the study of noise and vibration. Energy within a system is dissipated by friction, heat losses and other resistances, and any damped free vibration will therefore diminish with time. Steady-state forced vibrations can be maintained at a specific vibrational amplitude because the required

1 The Mechanics of Vibration By R. E. D. Bishop, D. C. Johnson The Mechanics of Vibration By R. E. D. Bishop, D. C. Johnson Originally published in 1960, the primary aim of this book was to give the reader an insight into the vibration characteristics of a machine or structure rather than to present them with a recipe for formal calculations.
Any vibration is described by the time history of motion, where the amplitude of the motion is expressed in terms of displacement, velocity or acceleration. Sinusoidal vibration is the simplest motion, and can be fully described by straightforward mathematical equations. Figure 1 shows the amplitude time plot of a sinusoidal vibration,
