Self-adaptive variable damping multi-dimensional nonlinear vibration isolation system and method
According to the self-adaptive variable-damping multi-dimensional nonlinear vibration isolation system and method, when the upper portion of a building structure is subjected to load pressure, for a vertical vibration load, a horizontally-arranged elastic plate is extruded, and displacement of the elastic plate is limited through a rigidity part of a vertical vibration reduction device; the piezoresistive sensor generates a corresponding current signal according to the pressure, and the controller changes the damping of the magnetorheological fluid and adjusts the size of a damper of the vertical vibration reduction device according to the size of the current signal, so that the self-adaptive variable damping of the damper is realized; when vibration loads in the horizontal direction are generated, the vertically-arranged elastic plate is extruded, displacement of the elastic plate is limited through the rigidity part of the horizontal vibration reduction device, the vibration loads in the direction are transmitted to damping parts in other directions through the damping part of the horizontal vibration reduction device, and energy consumption is conducted at the same time. Vibration loads in multiple directions borne by the building structure can be reduced at the same time.
