DEWESoft Vibration Shakers
Modal Shakers
Modal testing can be performed with modal hammers or shakers. If high-frequency excitation content or signal-controlled testing is desired, then modal shakers are the only excitation solution. Dewesoft modal shakers are lightweight and powerful modal shakers which can go up to 15,000 Hz and provide force levels up to 440 N with a maximum 25 mm stroke.

Inertial Shakers
Inertial shakers are used for structures requiring excitation in lower frequency bands. The shakers are directly connected to the structure and the inertia motion of the shaker mass provides the necessary forces to the structure. The shakers have a small, lightweight design that provides high mobility. They are fully enclosed, can be mounted on to structures at any angle - they are entirely self-supporting.

Permanent Magnet Shakers
Tests with permanent magnetic shakers can be driven at different frequencies and amplitudes. In these tests the test specimen can be directly fixed to the shaker armature and vibrating surface area can be enlarged by using a head expander according to the specimen sizes. The vertical excitation can be translated into horizontal excitation by using slip table. Permanent magnet shakers are trunnion-mounted, robust and compact, yet lightweight and powerful general-purpose vibration testing systems which can be used for modal and vibration testing.
