Tensile type three-dimensional vibration isolation device with vertical damping
The invention relates to a tensile three-dimensional vibration isolation device with vertical damping, and belongs to the technical field of civil engineering vibration control. Comprising a vertical stiffness element, an auxiliary vertical stiffness element, a sealed pore viscous damping cylinder, an upper cover plate, a single-face concave upper plate, a single-face concave bottom plate, a double-face concave middle plate and a convex sliding body. The three-dimensional vibration isolation device further comprises an upper shearing piece, a lower cylinder with a middle transverse plate, a shape memory alloy wire, an upper outward-extending plate with a friction material and a lower outward-extending plate with a friction material, and bridging pieces are arranged at the two ends of the double-face concave middle plate. The upper shearing part is fixed to the center of the lower surface of the upper cover plate, the lower barrel with the middle transverse plate is fixed to the center of the upper surface of the single-face concave upper plate, and the two ends of the shape memory alloy wire are fixed to the outer wall of the lower barrel with the middle transverse plate. The problems of tensile reliability and structural stability under three-dimensional vibration isolation of constructional engineering can be effectively solved, and vibration and earthquake double control of the constructional engineering based on three-dimensional vibration isolation is truly achieved.
本发明涉及一种带竖向阻尼的抗拉型三维隔振装置，属于土木工程振动控制技术领域。包括竖向刚度元件、辅助竖向刚度元件、密封式孔隙粘滞阻尼筒、上盖板、单面凹形上板、单面凹形底板、双面凹形中间板以及凸状滑动体；所述三维隔振装置还包括上剪切件、带中间横板的下筒、形状记忆合金丝、带摩擦材料的上外伸板以及带摩擦材料的下外伸板，所述双面凹形中间板两端设置有挑板；上剪切件固定于上盖板的下表面中心，带中间横板的下筒固定于单面凹形上板的上表面中心，形状记忆合金丝的两端固定在带中间横板的下筒的外壁。本发明能有效解决建筑工程三维隔振下的抗拉可靠性与结构稳定性问题，真正实现建筑工程基于三维隔振的振震双控。
