Head Expanders for Vertical Vibration Testing
THP Systems supplies head expanders engineered to increase the usable mounting area on an electrodynamic shaker while preserving stiffness and clean transmissibility. Options include aluminium and magnesium constructions for optimal strength to weight, with precision hole patterns matched to your armature and test article. We also provide thermal barriers that isolate the shaker from chamber heat or cold to protect bearings, adhesives and coils during combined environment tests.

Aluminum & Magnesium Head Expanders
Designed for High-Frequency testing, Head Expanders can be made from...View Details
Stiff. Lightweight. Application Tuned.
- Aluminium or magnesium head expanders sized to payload, spectrum and stroke
- High stiffness rib or honeycomb top plate designs to suppress rocking and local modes
- Custom hole patterns with inserts and bushings for repeatable fixturing
- Precision machining and flatness control for clean transmissibility
- Optional thermal barriers to limit heat transfer when used with chambers
- FEA supported design with modal targets and mass budget control
- Lifting points and edge protection for safe handling and durability
From Prototype Fixtures to Production Rigs
- Scale the mounting area for large or irregular DUTs without changing the shaker
- Integrate environmental chambers using thermal barriers to protect the armature
- Match bolt patterns and CG to minimise overturning and ensure stable control
- Commissioning support with on site checks for resonance, transmissibility and alignment
- Lifecycle service including inspection, refurbishment and flatness restoration
