Displacement steering synergistic mechanism type ternary self-adaptive nonlinear tuning vibration absorption system
The invention relates to a displacement steering synergistic mechanism type ternary self-adaptive nonlinear tuning vibration absorption system. A control box is connected with a controlled structure through a tuning unit; liquid, a first fixed semi-magnet disc, a semi-magnet piston disc and a second fixed semi-magnet disc are arranged in the control box, one side of the displacement steering synergistic mechanism is connected with the semi-magnet piston disc through a transmission rod, and the other side of the displacement steering synergistic mechanism is connected with a controlled structure through an inerter. Compared with the prior art, liquid convection components are used for generating hydraulic mass, liquid pulse components are used for generating nonlinear hydraulic damping, nonlinear electromagnetic negative stiffness is provided for vibration control of the structure, and the nonlinear inerter behavior is achieved through nonlinear motion conversion of the displacement steering synergistic mechanism. A parallel mechanism of the synergistic hydraulic mass unit and the nonlinear hydraulic damping unit is established, a parallel mechanism of the electromagnetic negative stiffness unit and the nonlinear inerter unit is established, and the synergistic self-adaptive vibration reduction effect based on displacement amplitude synergy is achieved.
