Abstract
Abstract A mounting for a rotary vibrator exciter for a two mass vibratory system wherein the rotary vibrator is mounted within a rectangular tubular frame which is connected to the structure to be vibrated by means of elastomeric blocks positioned on both of the horizontal and the vertical sides of the frame. By variation of the number, sizes, placement or compression of the elastomeric blocks the transmitted vibratory force component in the vertical and horizontal directions can be independently adjusted in order to obtain the desired vibratory motion in the vibrated structure and the desired natural frequency of vibration of the vibratory system.
