Vibration testing is done to introduce a forcing function into a structure, usually with the use of a vibration test shaker or vibration testing machine. These induced vibrations, vibration tests, or shaker tests are used in the laboratory or production floor for a variety of things, including qualifying products during design, meeting standards, regulatory qualifications (e.g. MIL-STD 810, etc.), fatigue testing, screening products, and evaluating performance.
Most often electrodynamic and servo hydraulic shakers are used, depending on the frequency range and displacement required. Data Physics, incorporating a long history of Ling Electronics technology, produces industry standard electrodynamic vibration and shaker equipment for vibration tests, vibration testing and shaker testing. Data Physics is a turnkey supplier of vibration test systems from electrodynamic shakers to intuitive and advanced vibration controllers.
Electrodynamic (ED) shakers are well suited for most vibration tests and offer several advantages over alternative approaches. Compared to hydraulic shakers, ED shakers are capable of much higher frequencies. These high frequencies can be very important in testing electronics and electronic assemblies. ED shakers are also capable of reproducing a wide range of shock and SRS pulses in addition to general vibration testing. Lastly, ED shaker have very linear behavior, so controlling the vibration test may be easier or possible when not otherwise possible.
Data Physics vibration test equipment provides a full range of shock and vibration testing that includes force generation, control, and measurement. Many advanced features are incorporated in both the hardware and software to provide state-of-the-art solutions for shock and vibration testing.
