Description
We designed a mechanical isolation system for a spherical resonant gravitational wave detector we are building in Brazil. We have used the finite element method to perform the dynamical analysis. The system is a multiple stage passive pendulum formed by cylinders joined by C springs and rods. Our results showed that the designed system could allow a 280 dB attenuation factor in the bandwidth, from 3.1 to 3.2 kHz, where the SCHENBERG detector will be sensitive
