This paper proposes a design optimization approach for core of solenoid actuators by combining optimization techniques with the finite element method (FEM). A solenoid is an important element part which hydraulically controls a transmission system, etc. The demanded feature of the solenoid is that it performs an electromagnetic force output being constant regardless of the stroke and being proportional to coil current. The plunger compresses a spring with a minimum force of 11 N over an 1.7 ㎜ travel. Compromise decision support problems (CDSP) are used to model engineering decisions involving multiple trade-offs. The approach utilizes a orthogonal polynomial model, the compromise decision support problem, which is a multi-objective formulation based on goal programming. The methodology is demonstrated as a CDSP tool for the design of a solenoid valve core.
