Tira vibration test systems - Swissvacuum.com

TIRA head expanders are manufactured from magnesium and
provide an expansion of the armature table up to a ratio of 2:1.
The unique design of the head expanders allows tests up to
2,000 Hz. Head Expanders especially provided with 'vibrodamp'
can be subjected to test frequencies above 1,000 Hz. This
damping process reduces amplification of upper frequency resonances.
Apart from the range of standard head expanders TIRA also
offer customer engineered fixtures for round, square or rectangular
working areas.
