ELECTRODYNAMIC INERTIAL VIBRATOR

摘要

An electro-dynamic inertial vibration exciter (1) for exciting a member (2) having capability to sustain and propagate input vibrational energy comprising a motor coil assembly (3, 4) having a coil (3) rigidly fixed to a tubular coil former member (4), a magnet assembly (5, 6, 7) disposed concentrically with respect to the motor coil assembly, and means (11) suspending the magnet assembly for axial movement relative to the motor coil assembly, characterised by a carrier (9) supporting the motor coil assembly (3, 4) and adapted for connection to the member (2) to be excited.
