본 논문에서는 설계변수 변화에 따른 특성을 빠른 시간 내에 파악할 수 있는 등가자기회로법(equivalent magnetic circuit method)을 활용하여 콜레노이드(colenoid) 타입의 선형 액츄에이터 설계 알고리즘을 제시하였다. 우선 선형 액츄에이터의 중요치수가 결정되면 등가자기회로법에 의해 슬롯 폭 비율 및 인가전류에 따른 클램핑력으로 파라미터 맵(parameter map)을 완성하고 이를 활용하여 효율적인 슬롯 폭 비율을 결정하였다. 또한 최대 클램핑력(clamping force)을 얻기 위해 극 폭 조절 알고리즘을 수행하여 최적의 극 폭 치수를 선정하였으며 이를 바탕으로 인가전류에 따른 클램핑력을 계산하여 40 kN 이상 출력하기 위한 최적의 극 수, 극 폭 치수 및 인가전류를 결정하였다. 제안된 설계 알고리즘은 최적설계 방법인 반응표면법(response surface method)과 비교하여 제안한 설계 알고리즘의 타당성을 검증하였다.

This paper performed the optimal design of electromagnetic linear actuator with divided coil excitation. The table of orthogonal array and response surface methodology (RSM) are applied to maximize the clamping force of the electromagnetic linear actuator with colenoid (COL) and multipolar solenoid (MPS) excitation. The analysis results show that the clamping force of the optimal models with COL and MPS excitation are increased by 41% and 54% at the gap of 0mm compared to the initial models, respectively.

The studies on the electronic control fuel injection system for a DI diesel engine have done for reducing the exhaust emission and improving fuel consumption. The electronic control fuel injection system is classified into a common rail system, a unit injector system and a high pressure injection system. The characteristics of these systems are largely depends on the operating characteristics of its solenoid that have high speed on-off operation. In order to improve these characteristics of fuel injection system, it is necessary to design the optimal shape of solenoid and select the input method of its power source. It was proposed HELENOID, COLENOID, DISOLE, and Multipole Solenoid in the studies of design for the optimal shape of solenoid. The studies on the energizing method, input method for power of solenoid were dealt with the conventional energizing method, the chopping method and the pre-energizing method. In order to find out the high response characteristics of solenoid, it is necessary to test the performance of optimally designed solenoid with a new energizing method. In this paper, the solenoid of multi-pole type with plat armature and its power control unit to control input current by the chopping method designed, and its response tests were performed according to its energizing conditions. As a result, the maximum input current for solenoid was controlled by the period of first stage exciting current and chopping duty ratio of control stage exciting current, and the fastest "on" time was able to get 0.46ms. The conditions of fastest "on" time was 0.3ms for first stage exciting current, 0.16ms for control exciting current and 75% for chopping duty ratio.
