유연 다물체 동역학 모델에 의한 트럭 프레임의 내구 해석
이철훈,김상섭 국민대학교 생산기술연구소 2003 공학기술논문집 Vol.26 No.-
This paper presents a method to predict durability of truck frame. A full vehicle model of the truck was constructed using ADAMS program. The truck model includes front and rear suspensions, tires, steering system, cab/cargo, and the flexible frame of the truck. Through the modal analysis of the FEA model of the truck frame, the appropriate vibration modes and static correction modes are selected. The dynamic stress of the truck was calculated by modal stress recovery method while the truck is running over durability road. The fatigue analysis was performed to predict the durability of the truck frame. The analysis results show the effectiveness of the proposed method.
