| Abstract: |
| This paper aims to provide the correlation between dynamic performance and temperature in high temperatures. In a series of high temperature conditions, the vibration and impact performance of isolators are tested. Some empirical formulas are summarized through those results using the least square method. The test results show that the dynamic performance of pressure-shear rubber isolators are related to temperature rather than temperature history. Furthermore, the first-order resonance frequency (ωT) and the absolute value of the impact response acceleration (GT) follow the first-order exponential decay function relationship with the changing of temperature, and the amplification factor (DT) follows the S-type function with the temperature. |
