Abstract

In this paper, we investigated the application of synchrophasing technique in controlling vibration of vibratory machines on a two-dimensional structure. Two cylinder machine models of even-mass distribution with four symmetrical supports installed on a periodic supporting structure model were analyzed. The main purpose of this research is to minimize the total structure-borne sound power transmitted from the machines to the supporting structure. In order to determine the structure-borne sound power, source mobility of the two machines was calculated theoretically. In addition, point mobility and transfer mobility between installation points on the supporting structure were calculated by the finite element simulation. Finally, the optimum phase angles between the two machines were searched for different frequencies of vibration. Optimized structure-borne sound power transmission was compared with structure-borne sound power transmission without control. The results confirm that synchrophasing technique can be an effective control technique in suppressing structure-borne sound power transmission of machines on a two-dimensional supporting structure.
