Abstract
The present disclosure discloses a three-dimensional seismic and vibration isolator with adaptive stiffness property in both vertical and horizontal directions. The isolator comprises an upper connection plate, a middle plate, an lower connection plate, a disc spring, a pre-compressed helical springs, a laminated lead rubber bearing, and viscous dampers. The upper connection plate, the middle plate and lower connection plate are made of high strength low carbon steel. The upper connection plate and middle plate are tightly contacted by the occlusive design, to guide the vertical motion. The vertical isolation system is made up of the disc spring, pre-compressed helical spring, and viscous damper. The horizontal isolation system comprises the laminated lead rubber bearing, pre-compressed helical spring and viscous damper. The disclosure adopts the theory of nonlinear adaptive vibration control technology and can be used to protect building structures or instruments from the seismic strikes or other environmental vibrations.
