    摘要:

    为研发一种自复位功能的刚性滑板?复位橡胶隔震支座,对支座刚性承压滑移元件摩擦特性、免承压复 位橡胶块剪切特性和整体支座的力学性能进行了试验研究,并采用 ABAQUS 有限元模型分析了整体支座的力学 特性。研究结果表明:刚性承压滑移元件动摩擦系数在 0.020~0.027 之间、免承压复位橡胶元件的水平等效刚度 为 129.33 kN/m;刚性滑板?复位橡胶隔震支座的塑性变形能力较强,具有很好的耗能性,该支座在小剪切位移下, 会是一种稳定性良好的隔震支座。

    Abstract:

    In order to develop a rigid sliding plate-reset rubber isolation bearing, the friction characteristics of the rigid bearing sliding element, the shear characteristic of the pressure-free reset rubber block and the mechanical properties of the whole bearing were studied. The mechanical properties of the whole bearing were also analyzed using the ABAQUS finite element model. The results show that, the dynamic friction coefficient of the rigid pressure-bearing sliding element is changing from 0.020 to 0.027, and the horizontal equivalent stiffness of the pressure-free reset rubber element is 129.33 kN/m. The rigid sliding plate-reset rubber bearing has strong plastic deformation ability and satisfactory energy dissipation ability. Which is considered as a kind of perfect stability isolation bearing under small shear displacement.
