MB Modal Exciters

Modal exciters are used for local excitation of different structures. Unlike traditional shaker systems modal exciters have no mounting table for attachment of the specimens. The weight of the moving element and the axial stiffness of the suspension of the moving element is reduced to a minimum to minimize the interaction between the structure and the modal exciter. The thru-hole armature allows the use of pre-stressed piano wires or typical modal stingers for connection of the modal exciter to the structure.

The availabe accessory kits include turnbuckels for suspended mounting, stingers, piano wires, bolt on masses and tools for easy adjustment of the test setup. Explore our inventory to find the modal exciter tha´s right for You...
