On a fundamental level, vibration testing can be categorized into three broad categories, sine vibration, random vibration, and shock. There are more complex forms of vibration testing, however, that would be a topic for another day.

Vibration testing can be described as a process of introducing repetitive mechanical energy in a controlled manner, distributed over a specific frequency range into a product in order to simulate the stress cycles experienced by the product in a specific environment.
The main purpose of this test is to reveal possible problems which would only...
