The Exact Closed-Form Expressions for Optimum Inertial Amplifier Coupled Nonlinear Friction Bearing Isolators
摘要
Due to their superior vibration reduction capacity, the base isolators [3] are widely applied to passive vibration control devices. The base isolation devices are installed between the superstructure and foundation to reduce the superstructural dynamic responses. New Zealand bearing [1], lead rubber bearing [9], resilient friction base isolator, friction pendulum system [7], pure-friction system [10], elliptical rolling rods coupled base isolation, and elastomeric rubber bearings [8] are some of the nonlinear base isolators.
