Two types of SB-system were subjected to the testing, namely high-friction (HF) type with friction coefficient of 0.13, and low –friction (LF) type with 0.015, respectively. During the loading, the stainless plate is mounted on an heat-insulation plate to prevent heat transfer to the testing machine. The friction coefficient of HF type decreased according to the temperature increasing. However, even after large cumulative sliding displacement, the PTFE still maintained proper characteristics. On the other hand, in the case of the LF type with PTFE-coated mating plate, until firs half of the test, the friction coefficient maintained stable regardless to the temperature increasing, then gradually the coefficient increased mainly because of the pealing of PTFE-coating of the stainless plate. When using LF type SB, this phenomenon should be considered in design of isolation system. The study verified stable characteristics of both SB systems under long duration dynamic loading.
