Vibration testing is the application of mechanical motion to a component, product, system or structure in order to observe its response or degradation over time. Although there is overlap between the two definitions, vibration testing is distinguished from mechanical shock testing by being applied for a longer period of time, ranging from a few minutes to many weeks.
