DESCRIPTION
Mini-shaker Type 4810 is of the electrodynamic type with a permanent field magnet. It is well-suited as the motive force generator in mechanical impedance measurements where only smaller forces are required. It can also be used in the calibration of vibration transducers, both to determine their sensitivity, by comparison with a standard accelerometer, as well as their frequency response, up to 18 kHz. The suspension system consists of radial flexure springs that restrict the moving element to almost perfectly rectilinear motion. Laminated flexure springs provide a high degree of damping to minimise distortion due to flexure resonances. The object to be vibrated is attached to the table by means of a 10 − 32 UNF screw, the thread size commonly used for mounting accelerometers.
