Vibration testing is the shaking of a product or package to determine its ability to survive in real world conditions. It is, in brief, is the shaking or shocking of a component or assembly to see how it will stand up to real world conditions. It is used in applications ranging from circuit boards and aircraft to vehicles and household appliances. Conducting these tests in the field or the laboratory involves the use of data analyzers, climatic chambers, controllers, instruments and vibration exciters. The procedure for vibration testing involves placing the product or package on a vibration testing table, which is driven so that the surface of the table vibrates. Shock and vibration testing is a subset of product and component testing, a larger category that includes electrical, life, environmental, exposure, dynamic, ergonomic and other specialized tests. Common capabilities of shock and vibration testing services (dynamics) include testing and simulation, component and product comparison, certification and qualification, data acquisition and instrumentation, design verification testing (DVT), failure mode and effects analysis (FMEA), sample preparation, and research and development. Safety, liability, performance, and in-line or in-process testing services are also available.
