Electromagnetic Shaker System

5000-pound shaker with slip table.

Our capability in structural dynamics  includes an electromagnetic shaker system to support the vibration testing requirements of our customers.  Key features of this Ling Dynamic Systems shaker system include:

• 5,000 pound force shaker capable of 5,000 lbf for sine or random and 15,000 lbf for shock.
• Dynamic range from d.c. to 3,000 Hz.
• Two-inch peak-to-peak displacement with velocities to 78 inch/second and accelerations to 60 g's.
• Seventeen inch diameter shaker head to accommodate large payloads.
• 24 inch by 24 inch oil film slip table assembly to accommodate horizontal or vertical testing
• M+p vibration controller providing graphical and numerical records of vibration test data for random, sine, sine dwell (resonance search), classic shock, and other types of excitation.
• Eight channels of built-in data acquisition with 8 or more additional external channels of data acquisition available if needed.

UDRI has been researching vibration analysis and control technology for over 30 years. We recognize that successful shaker testing requires more than just shaker operation. We have experience and in-house capabilities in all areas related to shaker testing, including:

• Design engineers and CAD facilities for fixture development.
• A machine shop for rapid fixture fabrication and modifications.
• Electrical engineering support for specialized instrumentation requirements.
• Extensive modal analysis equipment for identification of resonant shapes.
• Acoustic measurement equipment for determination of noise sources and amplitudes.
• Field portable data acquisition systems for measuring appropriate spectra for driving components on the shaker
• Structural analysis capabilities, including finite element analysis tools, for developing solutions to resonant part failures.
