3-D Eddy Current Analysis of Linear Solenoid Using A New Auto Mesh Coupling Method

Abstract

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.
