This paper describes the static and dynamic characteristics and the application of silicone gel. The dynamic characteristics are experimentally investigated to 200 Hz. The static relation between the draw ratios and the stress is expressed by the three-dimensional relation of the ideal rubber. The dynamic stiffness increase and the viscous damping coefficient decrease with an increase in the frequency. Their values increase as the draw ratios are decreased. The gel is applied to the spring-mass system and the beam system. As a result, the applications of the gel restrain the resonance gain of the system that doesn't have the gel. The restraining effect increases with a decrease in the draw ratios. Results of the analysis show that the damper of the gel restrains the gain of their systems and is superior to the rubber.
