Multistage damping wall based on magnetic field alternating type particle damping-lead damping
The invention discloses a multistage damping wall based on magnetic field alternating type particle damping-lead damping. The multistage damping wall comprises a wall body, a structural opening, wavypiezoelectric ceramics, an insulating piece, a damper cavity, a cavity bracket, a circular hole, electromagnetic particles, an exciting coil, a baffle plate, a square pipe, a rectangular plate, a groove, a lead filling hole, a lead brick, a penetrating hole and an insulating plate. According to the multistage damping wall, when the electromagnetic particles collide with a main body structure, themultistage damping wall generates electric energy through the wavy piezoelectric ceramics, current generates an alternating magnetic field when passing through the exciting coil, and the direction ofthe magnetic field is always consistent with the particle motion direction to accelerate particle motion, so that the collision times of the electromagnetic particles and the main body structure are increased, and the momentum interaction efficiency between the electromagnetic particles and the main body structure is improved; the sufficient energy consumption capacity is realized, a lead energy consumption device can provide lateral stiffness for the main body structure; and in addition, when the lead brick yields, the lead brick can fully play the energy consumption function, so that the anti-seismic property of the wall is more excellent to reduce the damage degree and the repairing cost of a structural main body during an earthquake.
