| 研究测试条件对液弹阻尼器动态特性的影响规律。结果表明:阻尼液耗散的能量占液弹阻尼器耗散能量的86.3%以上,随剪切振幅和剪切频率的增大,液弹阻尼器的耗能能力显著提高;液弹阻尼器的弹性刚度和阻尼刚度随剪切振幅的增大而减小,随剪切频率的增大而增大;当剪切振幅由0.2 mm增大到1.5 mm时,液弹阻尼器的阻尼刚度减小42.7%,当剪切频率由0.5 Hz增大到4 Hz时,液弹阻尼器的阻尼刚度由2 213 N·mm-1增大到5 802 N·mm-1。 |

| The influence of test conditions on the dynamic characteristics of the fluid-elastomeric damper was investigated.The test results showed that the energy loss of the damping fluid accounted for more than 86.3% of the energy loss of the fluid-elastomeric damper,and the energy loss capacity of the fluid-elastomeric damper increased significantly with the increase of shear amplitude and frequency.The elastic stiffness and damping stiffness of the fluid-elastomeric damper decreased with the increase of shear amplitude and increased with the increase of shear frequency.When the shear amplitude increased from 0.2 mm to 1.5 mm,the damping stiffness of the fluid-elastomeric decreased by 42.7%.When the shear frequency increased from 0.5 Hz to 4 Hz,the damping stiffness of the fluid-elastomeric increased from 2 213 N·mm-1 to 5 802 N·mm-1. |
