摘要

为提高电涡流阻尼器输出的阻尼力，提出一种多层磁场旋转式电涡流惯容阻尼器(Multilayer Magnetic Field Rotary Eddy Current Inertial Damper, MMF-RECID)，对其力学性能进行试验研究和有限元仿真。首先，介绍MMF-RECID的构造，建立MMF-RECID轴向力计算公式；然后，详细介绍了MMF-RECID试验样机，并考察在轴向反复荷载作用下MMF-RECID的惯容效应和耗能滞回性能，对MMF-RECID的轴向力组成进行分析，通过ANSOFT Maxwell软件对MMF-RECID的电涡流阻尼进行三维瞬态数值仿真，最后对一个设置MMF-RECID单自由度结构的减震效果进行分析。结果表明：（1）MMF-RECID的滚珠丝杠传动系统实现了惯性质量和电涡流阻尼力的双重增效，多层磁场输出的电涡流阻尼力符合磁场线性叠加的规律，滞回曲线稳定、饱满；（2）加载频率会改变MMF-RECID滞回曲线主轴方向的斜率以及轴向力的组成比例；（3）ANSOFT Maxwell三维瞬态仿真结果与试验结果具有一致性。（4）MMF-RECID具有良好的减震效果，且耗能密度高，具有工程应用可行性。

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.
