Abstract

The metal rubber bearing has excellent characteristics such as anti-fatigue, anti-aging and anti-corrosion, while the vehicle live load will cause fatigue damage to the metal rubber bearing and thus affect its shear mechanical properties. This paper is based on 2 million times of vertical fatigue test and fatigue before and after the shear test to investigate the fatigue damage on the metal rubber bearing shear mechanical properties. The test results show that: after the fatigue test, the hysteresis curve of the bearing is fuller than before fatigue, and the basic symmetric shuttle shape before fatigue is changed to asymmetric shape after fatigue; fatigue damage reduces the equivalent stiffness of the bearing and the stiffness after yielding, while the horizontal energy dissipation capacity of the bearing and the damping performance are improved.
