Abstract

Super high damping rubber (HDR-S) isolators show about 20 % higher damping characteristics than conventional high damping rubber (HDR) isolators. The characteristics of HDR-S isolators depends on the shear strain, temperature, and loading cycles. Especially the characteristics between the virgin loading and the sebsequent loading are drastically different. The objective of this study is to pursue realistic dynamic response of HDR-S isolators in the virgin loading state based on the results of the pseudodynamic tests.
