Head expanders and special fixtures
(800x800 mm)
TIRA head expanders are manufactured from magnesium and provide an expansion of the armature table.
The unique design of the head expanders and special control strategies allow tests up to 2000 Hz (depends on resonance frequency). Head expanders especially provided with 'vibrodamp' can be subjected to test frequencies above 1000 Hz. This damping process reduces amplification of upper frequency resonances.
If a test needs excentric clamping of the testobject or higher transverse moments, TIRA also offers guided head expanders.
Apart from the range of standard head expanders TIRA also offers customized fixtures for round, square or rec tangular working areas up to 2000 mm lateral length or diameter.
