Floating slab vibration isolation device with high static and low dynamic stiffness characteristics
The invention provides a floating slab vibration isolation device with high static and low dynamic stiffness characteristics, which comprises a device bottom plate, a sleeve bottom plate mounted on the device bottom plate, a sleeve limiting cushion block mounted on the sleeve bottom plate, a prestressed spring sleeved outside the sleeve limiting cushion block, and a prestressed spring sleeve sleeved outside the prestressed spring, the lower end of the prestressed spring sleeve is clamped and matched with the sleeve bottom plate, so that the prestressed spring is in a compressed state; a balance limiting cushion block is installed on the prestress spring sleeve, the balance limiting cushion block is sleeved with a balance spring, the upper end of the balance spring is connected with a device top plate, and the axis of the balance spring coincides with the axis of the prestress spring. According to the floating slab vibration isolation device with the high static and low dynamic stiffness characteristics, static high stiffness and dynamic low stiffness can be considered at the same time, and the vibration isolation effect is good.
本发明提供了一种具有高静低动刚度特性的浮置板隔振装置，包括装置底板，装置底板上安装有套筒底板，套筒底板上安装有套筒限位垫块，套筒限位垫块的外部套装有预应力弹簧，预应力弹簧的外部套装有预应力弹簧套筒，且预应力弹簧套筒的下端与套筒底板卡装配合，以使预应力弹簧处于压缩状态；预应力弹簧套筒上安装有平衡限位垫块，平衡限位垫块的外部套装有平衡弹簧，平衡弹簧的上端连接有装置顶板，且平衡弹簧的轴线与预应力弹簧的轴线相重合。本发明提供的具有高静低动刚度特性的浮置板隔振装置，能够同时兼顾静态高刚度和动态低刚度，隔振效果良好。
