In this paper, a three-dimensional finite element model based on the multi-pixel was constructed to accurately predict electric field distributions including an interference phenomenon between adjacent pixels in the liquid crystal of a complicated TFT-LCD panel. Utilizing the elaborate numerical model, the characteristics of spatial electric field distributions depending on various fault-electrode conditions are thoroughly examined on the basis of the field distribution of a normal electrode condition. The validity of the proposed model is proved by comparing the simulation results with those of the existing optical inspection equipments.

This paper presents a novel methodology for improving the reliability of electromagnetic devices and machines based on the reliability-based design optimization method. To achieve this, the method includes reliability analysis and optimization process taking into account uncertainties of design variables. One of the first-order reliability analysis techniques, called reliability index approach, is adopted to evaluate the reliability of performance functions with respect to probabilistic design variables. The proposed method has been successfully applied to designing a superconducting magnetic energy storage system. For verifying the efficiency and accuracy of the method, the results are compared with those of conventional optimization methods.

본 논문에서는 제품의 설계과정에서 발생하는 불확실 요소를 고려하기 위하여 확률정보를 이용한 신뢰도 기반 최적설계 기법을 제시하였다. 일차근사신뢰도법(first order reliability method : FORM)을 사용하여 신뢰도 지수를 계산하여 설계에 적용하였다. 제안된 설계 기법의 타당성을 검증하기 위해 정확성이 높은 몬테카를로 수치모사기법(Monte Carlo simulation method : MCS)을 통하여 제안된 기법의 적합성을 검증하였다.
