Abstract

Several vibration isolation methods are investigated using the 3-D direct Boundary Element Method. The results of the present numerical simulation are first compared to an analytical and other numerical solutions. After this validation of the used programming, an active isolation example from literature is treated. A comparison between numerical results and measured data is finally presented for the case of passive isolation by an open trench, that was constructed for full scale testing. The influence of different parameters on the amplitude reduction due to the presence of a trench is studied.
