ON/OFF 솔레노이드 작동에 의한 스프링 핀의 구조최적설계

ON/OFF Solenoid valve is used to control locking lever to transfer from 2WD to 4WD in specific situation. ON/OFF Solenoid with high spring load and magnetic force requires the structural optimization which satisfies both durability and variation of spring pin. This paper propose a design optimization approach for spring pin solenoid valve by combining optimization techniques with the finite element method (FEM). The structural optimization of spring pin is based on Taguchi method. The spring pin was designed to minimize stress and deformation. As a result of optimum design, the dimension of spring pin meets the design requirement.
