물질의 B-H 곡선에 따른 솔레노이드 밸브의 흡입력 특성 전자기적 수치 해석

In this paper, we perform a three-dimensional electromagnetic finite element numerical analysis applied axially symmetrical shape of a typical solenoid valve. parts of the solenoid valve Inner Yoke, Outer Yoke, Armature was to change the material of the attraction force characteristics according to identify current and the stator and the plunger clearance derives an analysis result. According to an analysis result, attraction force in increasing as clearance decreasing and property of b-h curve greater. Especially, it was figured out that the armature made of materials with better B-H curve characteristics increases the attraction force more than the armature made of the same material as the Inner and Outer Yokes.
