リニア電磁ソレノイドの動的応答解析

抄録

This paper proposes a computational method for predicting the dynamic response characteristics of a long-stroke(7 mm) linear electromagnetic solenoid with an armature of complicated shape. In this method, the magnetic field is completely coupled with the electrical supply and the mechanical movement of the actuator, employing the axisymmetric finite element method (FEM). The utility of this method is verified by comparing the computed results with the measured results.
