Annular spring composite conical lead pad two-stage variable stiffness vertical vibration isolation support and vibration double-control support
The invention discloses an annular spring composite conical lead pad two-stage variable stiffness vertical vibration isolation support and a vibration double-control support. The vertical vibration isolation support comprises a support upper connecting unit used for being fixedly connected with an upper structure; the support lower connecting unit is arranged below the support upper connecting unit and used for being fixedly connected with a lower structure; the two-stage variable-stiffness vertical vibration isolation unit is mounted between the support upper connecting unit and the support lower connecting unit, and comprises an upper inner-ring ring spring composite conical lead pad, a lower inner-ring ring spring composite conical lead pad and an outer-ring ring spring; the upper inner ring spring composite conical lead pad and the lower inner ring spring composite conical lead pad are partially embedded in the outer ring spring from the upper portion and the lower portion respectively. Through the combined vibration isolation unit of the annular spring and the conical lead pad, in the initial first-stage loading range, the conical lead pad is pressed to deform, the vertical rigidity of the vertical vibration isolation unit is low, and in the second-stage loading range, the inner ring spring generates inward annular compression deformation, and the outer ring spring generates outward annular expansion deformation; the vertical rigidity of the vertical vibration isolation unit is increased, double-order variable-rigidity vertical vibration control is achieved, and the vibration isolation effect is remarkably improved.
本发明公开一种环形弹簧复合锥形铅垫双级变刚度竖向隔振支座及振震双控支座。竖向隔振支座包括：支座上部连接单元，用于与上部结构连接固定；支座下部连接单元，布置于所述支座上部连接单元的下方，用于与下部结构连接固定；双级变刚度竖向隔振单元，安装于所述支座上部连接单元和支座下部连接单元之间，包括上部内圈环簧复合锥形铅垫、下部内圈环簧复合锥形铅垫和外圈环簧，上部内圈环簧复合锥形铅垫和下部内圈环簧复合锥形铅垫分别由上部和下部部分地内嵌于所述外圈环簧内。本发明通过环形弹簧与锥形铅垫的组合隔振单元，在初始第一级加载范围内，锥形铅垫受压变形，竖向隔振单元竖向刚度较低，在第二级加载范围内，内圈环簧发生向内的环向压缩变形，外圈环簧发生向外的环向膨胀变形，竖向隔振单元的竖向刚度变大，实现双阶变刚度竖向振动控制，显著提升隔振效果。
