Powertrain simulation is important fur the analysis of a vehicle performance. Automotive powertrain has been considered as the unified system and should be remodeled, whenever a powertrain system is changed. In this study, a new method is proposed for the synthetic modeling for the automotive powertrain. Components are separated from the powertrain system and constructed the matrix through dynamic relationships. The dynamic equation of the total powertrain system can be driven from the combination of each component. In order to combine each component, the superposition method is modified for the powertrain composition.

이 논문에서는 내부에 비정상 유동이 흐르는 균일한 직선 파이프에 대한 스펙트럴요소모델을 개발하였다. 개발된 스펙트럴요소모델에 대한 스펙트럴요소행렬은 주파수 영역에서 구한 파이프 역학 방정식의 엄밀해를 이용하여 유도되었다. 이 스펙트럴요소모델의 정확성을 평가하고 한 예제 파이프 계의 진동특성과 파이프 내부 유동특성을 고찰하기 위하여 스펙트럴 동역학 해석을 수행하였다.
