Novel three-dimensional vibration isolation device
The invention discloses a novel three-dimensional vibration isolation device. The novel three-dimensional vibration isolation device mainly comprises a horizontal vibration isolation device, a vertical vibration isolation device, a connecting and limiting device and the like; the horizontal vibration isolation device comprises a guide rail, a rubber support and an Euler beam; and the vertical vibration isolation device comprises a disc spring, a loading ring and a spiral spring. According to the novel three-dimensional vibration isolation device, lower horizontal rigidity is obtained through combination of the negative rigidity characteristic of the Euler beam and the rubber support and the guide rail, and a good horizontal shock (vibration) isolation effect is achieved; the vertical shock(vibration) isolation device with the quasi-zero stiffness characteristic is formed through combination of the negative stiffness characteristic of the disc spring and the spiral spring; and the horizontal vibration isolation device and the vertical vibration isolation device move to be decoupled, so that a three-dimensional shock (vibration) isolation effect is achieved. The novel three-dimensional vibration isolation device is suitable for buildings, instruments or equipment sensitive to environmental vibration, and has an excellent shock (vibration) isolation effect and certain tensile capacity.
本发明为一种新型三维隔振装置，主要有水平隔振装置，包括导轨、橡胶支座和欧拉梁；竖向隔振装置，包括碟形弹簧、加载环、螺旋弹簧；连接与限位装置等。本发明利用欧拉梁的负刚度特性，结合橡胶支座和导轨得到较低的水平向刚度，起到良好的水平隔震(振)效果；利用碟形弹簧的负刚度特性，结合螺旋弹簧组成带准零刚度特性的竖向隔震(振)装置；二者运动解耦，实现三维隔震(振)的效果。本发明适用于对环境振动敏感的建筑物或者仪器、设备，具有优良的隔震(振)效果，还具有一定的抗拉能力。
