Abstract
This paper deals with development of new isolation device by using friction force. This isolation device carries out reduction of horizontal relative displacement by using friction force. The isolation device uses a slope plate. The Friction force acts on the slope plate. The restoring-force is given to the isolation device from the compression spring attached to the base. In the equation of motion of analytical model, the friction force changes in proportion to displacement. The restoring-force is also proportional to displacement. The restoring-force always works in the direction of a center. Therefore, the friction force and restoring-force are proportional to displacement. Simulation analysis is calculated on various conditions using the analysis model. Condition reducing both response acceleration and displacement effectively is examined. Furthermore, an experiment is conducted using the experimental model. The experimental results are compared with analysis results. The performance of the isolation device is examined. The validity of the performance is shown.
