Abstract

 This paper presents shape optimization of moving core type solenoid actuator driven by

DC source. 3-D axisymmetric finite element method(FEM) is used for the electromagnetic

field analysis and saturation effect of the magnetic material is considered. The mechanical

dynamic equation and electrical circuit equation are also coupled.

In the dynamic characteristic by FEM, we adapt a moving line technique to save

computation time and to perform the process efficiently. Among the optimization

algorithms, sequential quadratic programming (SQP) is carried out for the shape

optimization. A good performance of optimized solenoid actuator has been verified

through the experiment.
