摘要:
为了改善涡流阻尼器在实际工程中的应用性,利用了外部电源改变装置内部磁通量大小,提出了一种新型主动控制式电磁涡流阻尼器(ElectromagneticEddyCurrentDamper,简称EECD)。首先考虑磁回路有效利用磁通量及转动装置放大导体板切割磁感应线的优点,进行阻尼器的结构设计,并对其工作原理进行详细地介绍。然后,利用电磁仿真软件(COMSOLMultiphysics)分析其在不同电流大小的情况下所产生的磁通量大小,并推导出相应磁感应强度理论公式,分析相同匝数,不同电流下的工况,结合实测数据,对比仿真、理论与试验的磁感应强度,验证理论的准确度。最后,推导出该阻尼器在电流稳定时等效阻尼系数,进而得出其电涡流阻尼力。研究结果表明:在研究速度范围内,EECD能达到设计目的,等效阻尼系数、惯质及电涡流阻尼力理论结果与试验结果基本吻合,且EECD阻尼性能接近线性;在研究速度范围内,随着电流的变化,电磁铁产生的磁通量大小及阻尼力也成正比变化;该装置滞回性能相对光滑,重复性较好,说明新型电磁式阻尼器力学性能稳定,具有可行性。
Abstract:
In order to improve the applicability of eddy current dampers in practical engineering, a new type of actively controlled electromagnetic eddy current damper(EECD)was proposed by using an external power supply to change the magnetic flux inside the device. Firstly, considering the advantages of the magnetic circuit effectively using the magnetic flux and the rotation device to amplify the conductor plate to cut the magnetic induction line, the structural design of the damper is carried out, and its working principle is introduced in detail. Then, the electromagnetic simulation software(COMSOL Multiphysics)was used to analyze the magnitude of the magnetic flux generated by the magnetic induction under different currents, and the corresponding theoretical formula of magnetic induction intensity was deduced. The working conditions under different currents with the same number of turns were analyzed, and the magnetic induction intensities in the simulation, theory, and experiment were compared based on the measured data to verify the accuracy of the theory. Finally, the equivalent damping coefficient of the damper under a stable current was derived, and then the eddy current damping force was obtained. The results show that the EECD can achieve the design purpose within the research speed range, the theoretical results of the equivalent damping coefficient, inertial mass, and eddy current damping force are basically consistent with the experimental results,and the damping performance of EECD is nearly linear;within the research speed range, with the change of current, the magnetic flux and damping force generated by the electromagnet also change proportionally; the hysteresis performance of the device is relatively smooth, and the repeatability is good,which indicates that the mechanical properties of the new electromagnetic damper are stable and thus the device is feasible.
