In this study, the performance of flame-retardant silicone foam was evaluated. Static characteristics were analyzed through uniaxial compression and simple shear experiments, and the material constant was derived using ANSYS. The static comfort evaluation index of silicone foam derived based on the experimental data was compared with that of polyurethane(PU) foam. The accuracy of the material constantly derived through finite element analysis was analyzed, and in this process, it was confirmed that the Ogden 2nd model was the most accurate and economical. The parameter was obtained through the optimization process, considering the viscoelastic characteristics of the specimen. The transmission rate characteristics in relation to external vibration frequency were analyzed using polyurethane foam. As a result, at frequencies between 2-5Hz, the transmission rate was close to 1, but at 18Hz, it was lower than 1. The behavior was similar to that of polyurethane foam.
