Head plate for coupling with vibration test system to provide a larger mounting surface for test items

During vibration testing, test items or fixtures are often larger than the shaker’s original armature surface. To solve this, an auxiliary head expander is mounted on top to create a wider mounting area.

When selecting or designing a head expander, it’s important to consider factors like usable frequency range, total mass, achievable acceleration, amplitude uniformity, and lateral motion limits. Each of these parameters impacts how accurately vibrations are transferred to the specimen.

Note: Customized shapes and sizes can be manufactured to match specific testing requirements or testing equipment configurations.

Auxiliary Support Systems

Auxiliary support systems are used to enhance the load capacity and guiding stability of the vibration shaker. They help maintain precise alignment and reduce unwanted movements when testing larger or heavier assemblies.

Quick Rotation Platforms

Quick rotation platforms integrate a lifting and locking mechanism on the expander support frame. This setup makes it possible to raise and secure the head expander, allowing the shaker to switch between vertical and horizontal orientations without needing to disassemble the test platform.
