Particle damping-lead damping multistage vibration reduction wall based on electromagnetic conversion function
The invention discloses a particle damping-lead damping multistage vibration reduction wall based on an electromagnetic conversion function. The particle damping-lead damping multistage vibration reduction wall comprises a wall body, a hole, waveform piezoelectric ceramics, an insulation block, a damper cavity, a cavity support, a round hole, particles, a magnetostrictive material, an exciting coil, a baffle, a square pipe, a rectangular plate, a groove, a lead filling hole, a lead block, a penetrating hole and an insulation plate. According to a particle damping device with the electromagnetic conversion function in the multistage vibration reduction wall, when the particles collide with a main body structure, electric energy is generated through the waveform piezoelectric ceramics, thenthe electric energy is converted into magnetic energy through the exciting coil, the magnetostrictive material is made to extend in the particle movement direction, movement of the particles is accelerated, the momentum exchange efficiency between the particles and the main body structure is improved, the enough energy dissipation capacity is achieved, a lead energy dissipation device can providelateral stiffness for the main body structure and meanwhile plays an energy dissipation role, the anti-seismic property of the wall is more excellent, and the damage degree and maintenance cost of thestructure main body in an earthquake are reduced.
