Three-dimensional vibration isolation device with sliding oblique springs
The invention discloses a three-dimensional shock / vibration isolation device with sliding oblique springs. The three-dimensional shock / vibration isolation device with the sliding oblique springs is formed by a horizontal shock / vibration isolation unit and a vertical shock / vibration isolation unit which are connected in series in the up and down direction. The horizontal shock / vibration isolation unit is a thin laminated rubber bearing with a large first shape coefficient and contains a high-purity lead core energy consumption unit. The vertical shock / vibration isolation unit is formed by connecting a thick laminated rubber bearing with a small first shape coefficient and oblique rectangular compression springs connected with vertical heavy-load linear guide rails in parallel, vertical shock / vibration is isolated together through elastic deformation of low hardness and high damping rubber and tension and compression deformation of the oblique rectangular springs linked with the linear guide rails, the first shape coefficient of the thick laminated rubber bearing and the stiffness coefficient of the rectangular springs can also be changed, vertical vibration at different frequencies and amplitudes is reduced, and three-dimensional shock / vibration isolation is realized. The three-dimensional shock / vibration isolation device with the sliding oblique springs belongs to a passive shock / vibration control measure and can be widely applied in shock isolation layers of upper cover structures of urban rail transit and the bottoms of important large and medium-sizedmechanical equipment.
本发明公开了一种带滑动斜弹簧的三维隔震/振装置，由上下串联的水平和竖向隔震/振单元组成。水平隔震/振单元为第一形状系数较大的薄叠层橡胶支座，包含高纯度铅芯耗能单元；竖向隔震/振单元由第一形状系数较小的厚叠层橡胶支座和连接竖向重负荷线性导轨的斜向矩形压缩弹簧并联组成，通过低硬度高阻尼橡胶弹性变形、线性导轨联动的斜向矩形弹簧拉压变形，共同隔离竖向震/振动，还可改变厚叠层橡胶支座的第一形状系数和矩形弹簧的刚度系数，减小不同频率和振幅的竖向振动，实现三维隔震/振。本发明属于一种被动式震/振动控制手段，可广泛应用于城市轨道交通上盖结构的隔震层和重要的大中型机械设备底部。
