TIRA offers a series of modal shakers from 100 N to 2.7 kN specifically designed to meet the demands made on modal and structure analyses.

Modal shakers up to 400 N are excited by permanent magnets. The shakers made with rare-earth magnets are particularly striking by their lightweight construction for mobile use. The design of modal shakers is characterised by high transverse vibration resistance and high axial stiffness. Modal shakers as from 1000 N permit a maximum travel of up to 50.8 mm. This is ensured by TMC control. The electronic TMC armature position control provides exact coupling of modal shakers to the specimen. A defined preload can easily be set. Axial stiffness can be adjusted electronically, too.

All modal shakers are equipped with a swivel frame in standard configuration. This allows a wide variety of coupling options.

The modal exciter system TV 51130-MSC is a special development of TIRA to increase the mobility. The 350 N vibration exciter has an integrated air cooling to make an external cooling unit unnecessary
