Negative Poisson's ratio lattice mechanics metamaterial shock insulation support
The invention discloses a negative Poisson's ratio lattice mechanics metamaterial seismic isolation support which comprises an upper connecting plate, a lower connecting plate, a seismic isolation element, a tensile device and a base with four adjusting mechanisms, the lower end of the upper connecting plate is fixedly connected with the seismic isolation element, the lower end of the seismic isolation element is fixedly connected with the lower connecting plate, and the lower connecting plate is fixedly connected with the tensile device. The tensile device is arranged between the upper connecting plate and the lower connecting plate, and the lower end of the lower connecting plate is connected with bases of the four adjusting mechanisms through chemical anchor bolts. The vibration isolation device has the advantages that the negative Poisson's ratio lattice mechanical metamaterial is adopted for vibration isolation, high compression resistance and high energy absorption and energy consumption performance are achieved, and the temperature dependence of a conventional rubber vibration isolation device is overcome. The support can be matched with a tensile device surrounding the periphery of the seismic isolation element, and the anti-drawing capacity of the support is improved. According to different structural performance requirements, the applicability of the shock insulation support can be improved by adjusting the lattice composition of the negative Poisson's ratio lattice mechanics metamaterial and the height of the shock insulation support.
本发明公开了一种负泊松比点阵力学超材料隔震支座，包括连接上板、连接下板、隔震原件、抗拉装置和带有四组调节机构的底座，所述连接上板下端固定连接有隔震原件，所述隔震原件下端固定连接有连接下板，所述抗拉装置设置于连接上板与连接下板之间，所述连接下板下端通过化学锚栓连接有四组调节机构的底座。本发明的优点在于：采用负泊松比点阵力学超材料进行隔震，不仅具有较强的抗压缩能力和高吸能耗能性能，而且克服了常规橡胶隔震装置的温度依赖性。该支座可配合环绕隔震原件四周的抗拉装置，提高了支座的抗拉拔能力。根据不同结构性能要求可以通过调节负泊松比点阵力学超材料晶格构成和隔震支座高度，增加本隔震支座的适用性。
