Friction sliding self-resetting three-dimensional shock isolation and reduction support
The invention discloses a friction sliding self-resetting three-dimensional shock insulation and reduction support. A combined support comprises an internal spring support and an external elastic rubber support. The internal spring support and the external elastic rubber support provide rigidity for the structure, meanwhile, the vertical vibration reduction and horizontal vibration isolation effects are achieved, and the multi-stage vibration reduction effect can be achieved by adjusting the contact of a friction pair and the rigidity of the rubber support to show various self-adaptive rigidities; the horizontal and vertical vibration effects can be effectively reduced on the whole, the good three-dimensional vibration isolation and reduction and horizontal self-resetting capacity is achieved, and the structure is simple. The vibration response of the superstructure and equipment adopting the support under the action of earthquake and rail transit or environmental vibration can be effectively controlled, and the safety and comfort of the superstructure and equipment under the action of earthquake and vibration are ensured.
本发明公开了一种摩擦滑移自复位三维隔震减振支座，组合支座包括内部弹簧支座和外部弹性橡胶支座。本发明通过内部弹簧支座和外部弹性橡胶支座为结构提供刚度的同时起到竖向减振和水平隔震的作用，并且能够通过调整摩擦副的接触与橡胶支座刚度表现出多种自适应刚度实现多级减振效果，总体能够有效减少水平和竖向振动作用，具有良好的三维隔震减振及水平自复位能力，且构造简单。采用该支座的上部结构和设备，在地震及轨道交通或环境振动作用下的振动响应可以得到有效控制，确保上部结构和设备在地震和振动作用下的安全性和舒适性。
