| 中文摘要: |
| 研究橡胶层厚度、螺栓转矩对橡胶型摩擦阻尼器力学性能和耐疲劳性能的影响。结果表明：随着橡胶层厚度的减小，橡胶型摩擦阻尼器的起滑位移、起滑阻尼力和摩擦负荷减小；随着螺栓转矩的增大，橡胶型摩擦阻尼器的起滑位移变化不大，起滑阻尼力和摩擦负荷先增大后减小，当螺栓转矩为400 N·m时，起滑阻尼力和摩擦负荷最大；橡胶型摩擦阻尼器的疲劳试验前后摩擦负荷-滑动位移滞回曲线饱满，耐疲劳性能优异，具有良好的耗能能力。 |
| 英文摘要: |
| The effects of the rubber layer thickness and bolt torque on the mechanical properties and fatigue resistance of the rubber friction damper were investigated.The results showed that，the initial displacement，initial damping force and friction load of the rubber friction damper decreased with the decrease of the rubber layer thickness. With the increase of the bolt torque，the initial displacement of the rubber friction damper changed little，the initial damping force and friction load increased first and then decreased. When the bolt torque was 400 N·m，the initial damping force and friction load were at the maximum. Before and after fatigue test，the friction load-sliding displacement hysteresis curves of the rubber friction damper showed that the damper had good energy dissipation capacity，indicating excellent fatigue resistance. |
