Vibration Shaker Selection Guide

The Modal Shop offers a new Vibration Shaker Selection Guide to help engineers meet their vibration control testing needs. Serving the vibration community for over 20 years, The Modal Shop understands that choosing the right electrodynamic shaker for a specific application and test setup is critical.  The vibration shaker selection guide breaks the process down in to four simple steps so that new users can quickly and easily identify the shaker system best suited to their applications.

Using the step by step process of the selection guide, a user determines the total mass of test items, or payload, and the acceleration necessary for testing. With values for payload and acceleration, users plot the point on capability graphs provided. The intersection of payload and acceleration establishes which shakers meet testing requirements. With a vibration shaker selected, the user verifies displacement requirements to ensure the shaker's stroke will not be exceeded during testing.

The Modal Shop's electrodynamic vibration shaker systems are rugged and portable. Ranging from 7 to 110lbf [31 to 489N], the vibration exciters are designed to accommodate a wide variety of testing situations. Easy to set up and simple to use, all shakers come complete with trunnion base, cables, and accessories. For other vibration test accessories, such as head expanders, isolation mounts and horizontal tables, contact the knowledgeable application engineering team at The Modal Shop for details.
