Modal shakers are used to study the vibration behaviour of structures. No specimen is mounted on these shakers. These shakers are attached to the structure with a stinger and the force is transferred from the shaker to the structure via this stinger. The structure under test and/or the modal shaker can be suspended during the test using components such as an elastic rope or spring to simulate free-free boundary conditions. In this way it is possible to excite the specimen at different frequencies. As a result, the natural frequencies and mode shapes of the structure can be calculated from the vibration values measured over the structure.
Dynalabs modal shakers are lightweight and powerful modal shakers capable of up to 12,000 Hz and force levels up to 440N with a maximum stroke of 20mm.
