Geometrically nonlinear vibration isolation system
The geometrically nonlinear isolation system of the present invention includes a bearing platform, an isolator and a damper. The isolator is connected with the bearing platform and used for providing resilience against horizontal relative displacement between the bearing platform and the isolator. The damper is pin-jointed to the bearing platform and has an axis orthogonal or oblique to the horizontal direction. Accordingly, when the bearing platform and the isolator move with respect to each other along the horizontal direction, the angle between the axis of the damper and the horizontal direction would change with the horizontal displacement, and the damper provides damping force along a direction parallel to the axis of the damper so as to enhance horizontal vibration isolation effect.
