Why Use Inertial Shakers?

When testing structures in the real world—bridges, vehicles, airframes, or even composite panel, applying controlled dynamic force can be challenging. Inertial shakers offer a practical solution: compact, self-contained units that attach directly to the structure and deliver excitation without requiring a separate reaction mass or base.

This makes them ideal for:

• Modal testing of large or in-situ structures

• Measurements in confined or remote locations

• Situations where fixed-base excitation is impractical or could affect the measurement

Data Physics inertial shakers are field-proven across industries and available in a range of sizes and force ratings. Whether you’re troubleshooting a design or validating a model, they provide clean, reliable input right where it’s needed.
