파워 글라스 시스템의 특성은 주로 윈도우 레귤레이터의 거동 특성과 글라스 런에 의한 저항에 의해 결정되며, 시험 결과 분석을 통해 시스템의 성능을 예측한다. 본 논문에서는 시험적인 방법의 한계를 해결하기 위해, 익스플리시트 코드를 사용한 해석적 방법을 제안하였다. 해석 모델에 사용한 글라스 런은 무니-리블린 모델을 사용하여 모델링 하였고, 다양한 조건에서의 마찰 시험을 실시하여 마찰계수를 구하였다. 또한, 윈도우 레귤레이터 파트의 메커니즘은 패스트 벨트 시스템과 슬립 링요소를 사용하여 모델링 하였고, 상승 시 발생하는 전류와 하중과의 상관관계 분석을 통해 레귤레이션 메커니즘의 신뢰성을 검증하였고, 모터의 특성을 고려하여 신뢰성 있는 글라스 상승 시간을 예측하였다.

Currently, automotive industries improve the vehicle performance and reduce the development period of vehicle using each module part for the high quality and performance of vehicles. However each component part doesn't generate the noise and vibration problems, sometime these problems are generated on the assembly status between vehicle chassis frame and each module part. On this study, in order to analysis the dynamic characteristics of a shield door module that is a typical module part of vehicles, the acquisition and evaluation process about the vibration and noise of shield door module is developed. Also the possibility to apply to shield door module of the developed process is verified by the comparison with the dynamic characteristics between plastic and steel module plate.

This study presents the evaluation process for door module. Its objective evades the resonance generated at module plate due to the operation of window regulator motor. For this study, the design improvement process is composed of experimental methods having three steps. First step is modal analysis at door assembly status for acquisition of dynamic characteristics which are modal frequency and damping. Second step is a vibration experiment to get the test mode considered an efficiency of window regulator motor. Last step is a vibration measurement by the form of $6{\times}6$ array on module plate. A vibration measurement of 6x6 array form can be got to three analysis results which are a transfer path of vibration using cross correlation function, a vibration map using OA level and a contribution by frequency band using coherent output power spectrum on module plate. These results are applied to SDM(structural dynamic modification) for design improvement to get around the resonance on module plate by the excitation of window regulator motor.
