摘要
由电磁学中的磁场对衔铁吸力公式,提出了涡流板相对磁盒运动时的切向磁电阻尼力模型,即假设涡流板相对磁盒运动时涡流板受到的切向磁电阻尼力与磁盒对涡流板法向吸力成正比,在此基础上研究了参数振动频率、运动幅值对阻尼力的影响规律并通过数据拟合得到了相应的公式,最后由恢复力模型公式画出的滞回曲线与试验滞回曲线进行了比较,效果较好。
By the electromagnetic formula of the magnetic field to the armature iron suction, it proposes the tangential magnetoelectricity damping force model in the relative movement of eddy current plate to magnetic box, Namely,in the relative movement of eddy current plate to magnetic box, there is a hypothesize that the tangential magnetoelectricity damping force and the magnetic box on the eddy current plate normal suction are proportional. On this basis, it studies the influencing law by parameter vibration frequency and movement amplitude to damping force, and through the data fitting,it obtains the corresponding formula. Finally, it compares the hysteretic curve drawn by the restoring force model formula with the experimental hysteretic curve. The effect is good.
