Anti-drawing three-dimensional vibration double-control decoupling system with quasi-zero stiffness

The invention provides an anti-drawing three-dimensional vibration double-control decoupling system with quasi-zero rigidity. The anti-drawing three-dimensional vibration double-control decoupling system comprises an upper structure, a vertical vibration/shock isolation device, a horizontal shock isolation device and a lower foundation. One end of the vertical vibration/seismic isolation device is connected with the upper structure, the other end of the vertical vibration/seismic isolation device is connected with the horizontal seismic isolation device, and the horizontal seismic isolation device is connected with the lower foundation. Different negative stiffness areas can be adjusted according to design, so that vibration double control is achieved, horizontal vibration isolation and vertical vibration isolation/vibration can be achieved at the same time, mutual decoupling is achieved, and the tension phenomenon does not occur in the whole system. 本发明提供了一种具有准零刚度的抗拉拔三维震振双控解耦体系，包括上部结构、竖向隔振/震装置、水平隔震装置以及下部地基；所
