Electromagnetic vibration generator
Meggitt Sensing Systems - Wilcoxon Research
The F10 vibration generator is a reaction-type shaker generating very large dynamic forces for structural excitation in vibration research and testing. The reaction principle of operation and compact configuration allow this generator to be stud mounted in any position, directly to structures without external support or critical shaft alignment problems.
The F10 is designed to encircle the Z820WA impedance dead. The relatively light coil and bobbin of the F10 generator are rigidly attached to the Z820WA impedance head and the heavy cylindrical magnets are suspended by two rubber diaphragms. The dynamic weight added to the test structure is relatively low since the rubber suspended weight does not affect axial or rotational inertia of the vibration generator core above the 25 Hz resonance frequency of the system.
