permanent magnet shaker
Bruel and Kjaer
The 400 Series electro-dynamic shakers are used to replicate vibration conditions in a controlled laboratory environment. These unit see frequent use in the analysis of dynamic behaviour of structures and small, lightweight components as well as assemblies testing. They are often found in different industrial applications as well as universities and research facilities. The 400 Series features a lightweight moving armature optimized for the lowest possible mass with a broad range of frequencies and an armature with bonded polypropylene flexures for axial support, test load and lateral and rotational restraint. It can be used with an optional cast trunnion frame (for 90° rotation) or bolted down to a suitable structure.
