本文采用考虑涡流的三维有限元方法分析了线性螺线管的动态特性。并提出了一种用于动态特性分析的自动网格耦合方法。通过实测结果的对比，验证了该方法的有效性。阐明了线形螺线管的形状和材料对涡流分布和磁通分布的影响。定量地阐明了外加电压波形对响应时间、涡流损耗和铜损耗的影响。
In this paper, the dynamic characteristics of the linear solenoid is analyzed by the 3-D finite element method taking into account the eddy currents. And an auto mesh coupling method for the dynamic characteristics analysis is proposed. The effectiveness of our method is verified through the comparison of the measured results. The influences of the shape and the material of the linear solenoid on the distributions of the eddy currents and the magnetic flux distribution are clarified. Furthermore, the influences of the applied voltage waveform on the response time, the eddy current loss and the copper loss are quantitatively clarified.
