Abstract

To improve the output damping force of the eddy current damper, a multilayer magnetic field rotary eddy current inertial damper (MMF-RECID) is proposed. The mechanical properties of MMF-RECID were experimentally studied, and the finite element simulations were carried out. Firstly, the structure of the MMF-RECID is described, and the calculation formulas of the axial force of MMF-RECID is derived. Then, the MMF-RECID specimen is described in detail, the inertial effect and energy dissipation hysteresis performance of MMF-RECID under recycled axial loading are investigated, and the axial force composition of the MMF-RECID is analyzed. By the ANSOFT Maxwell software, the three-dimensional transient numerical simulations of eddy current damping of MMF-RECID are carried out. Finally, the earthquake-reduction effect of a single-degree-of-freedom structure equipped with MMF-RECID is analyzed. The results show that: (1) the ball screw system of MMF-RECID realizes the multiplicative effect of inertia mass and eddy current damping force, the eddy current damping force of multi-layer magnetic field versus a single-layer magnetic field conforms to the law of linear superposition, and the hysteresis curves are stable and full; (2) the loading frequency will change the main axis slope of the MMF-RECID hysteresis curve and the composition ratio of the axial forces; (3) the results of the ANSOFT Maxwell three-dimensional transient simulation are consistent with the experimental results; (4) MMF-RECID has a good damping performance with high energy density, and has promising engineering practicability.
