【 摘 要 】

In the paper are presented two seismic isolation systems. One is classic, made out of two rubber plates, with a metallic plate vulcanized between the two. For fastening, the isolator has another two clamping plates vulcanized on it. The proposed model has same components as the classical one, having on top and under, attached to the rubber, two thin plates with bossages. For fastening the insulator there are two plates for clamping, which are not vulcanized to the isolator. The contact between the insulator and the clamping plates is made just by the bossages, the rest of the surface being free. As a result of the simulations done in the SolidWorks softwarewe concluded that, in the case of the proposed model, the rubber has no longer the tendency to detach from the clamping plates. As long as the bossage plates are moving together with the rubber, the whole isolator becomes more elastic and durable in time.
