Abstract It is found that the performance of rubber bearing dominated by carbon black (CB) filled whose dynamic mechanical properties are sensitive to frequency, temperature, and strain amplitude. Due viscoelasticity, hysteresis loss represents energy dissipation, which can reflect damping capacity CB‐filled rubber. Besides, dissipation positively correlated with modulus. However, in practice, only considered a structural vibration measure, keeps service for long time under various loading conditions. The current research on accelerated prediction method modulus limited. To this end, tests carried out. Based time–temperature superposition principle (TTSP), master curve long‐term be obtained, accuracy shift factors verified use Williams–Landel–Ferry (WLF) equation. When temperature rises above −10°C, it obvious there linear relationship between factor temperature. Therefore, an empirical proposed relationship. results show very useful predict rubber, indicates cost significantly reduced because simplicity comparison WLF Highlights Effect prestrain viscoelasticity. A condition proposed. superior from aspect cost.
