| Product List | 
The purpose of vibration testing is to make a series of controllable vibration simulations in the lab, no matter generated by natural or man-made vibration environments; such as waves, tidal flaps, wind, earthquake or rain, and so on. It is to test if the product is capable of sustaining the vibration environment exerted from transporting or usage along its effective life cycle and certify the standard of design & functional requirement of the product. The value of vibration testing is to confirm the reliability of products and effectively screen out the bad products in the factory; avoiding damages occurred at arrival; and to assess the failure analysis on the non-performing products; expecting to reach a high standard, high-reliability products. The vibration test stresses the continuity and fatigue; and contributes to the understanding of the product’s status under vibration circumstance in a normal environment, and avoids the product’s unpredictable damage caused under certain vibrating frequency for a long time.
A Vibration Test System consists of four major components (shown in Figure A-1):
1. The Shaker
2. The Power Amplifier
3. The Cooling Blower
4. The Measurement and Control System
a) Accelerometers and Cables
b) Charge Amplifier, depending on which type of Accelerometers.
c) Control System, sometimes including DATA Analysis Software
