Abstract

In order to evaluate control performances of different feed-forward strategies for sound radiated from the flexible base of a two-stage vibration isolation system, a mathematical model of a two-stage vibration isolation system mounting on a rectangular plate was established. Two vibration and two sound radiation oriented cost functions were chosen and the acoustic radiation power after control was focused. Besides, the control performances were comprehensively discussed by taking parameters like sound pressure distribution, and control force into account. Then the advantages and disadvantages of different control strategies were evaluated. The simulation results show that the vibration oriented control strategies could induce the increase of radiated power at specific frequencies while the control performance of sound radiation oriented strategies may be obtained with enlarging vibration power and large control force amplitude. In addition, the effect of the location of control force on sound radiation was discussed.
