Product Description

Description of Beam Bending Vibration Module

Experimental module, which fits into the Vibration Frame making up part of the Universal Vibration Apparatus. A flexible beam is supported between two end brackets which create simply supported end conditions. One end bracket allows pivoting only whilst the other allows rolling and pivoting only. One of the brackets is supported on vertical supports that can be moved depending on the beam length being used. The vertical brackets and standard length beam are both supplied.

The Beam Bending Vibration Module is forced to vibrate using a motor exciter. This motor exciter can be attached anywhere along the beam length between the brackets. The motor exciter is supplied as standard and has two eccentric masses attached directly to the motor spindle at either end. This allows high rotational speeds to be achieved. A speed sensor on the motor exciter monitors the speed of rotation of the eccentric masses and outputs Beam Bending Vibration Module.

Experimental Capabilities of Beam Bending Vibration Module
