초기 인장력을 고려한 파이프계의 자유진동 시뮬레이션 A Simulation for the Free Vibration of Pipe Systems Considering Initial Tension 저자 최명진 학술지정보 한국시뮬레이션학회 논문지 KCI 발행정보 한국시뮬레이션학회 1998년 피인용횟수 0 자료제공처 KISTI 주제분야 공학 > 기타공학 <초록> Using finite elements, a simulation is prformed for the pipe systems to investigate free vibrational characteristics, that is natural frequencies, considering the intial tension due to the velocity and the pressure of the inside fluid flow. To confirm the program developed in this study, the results are compared with the results of commercial software ANSYS. When the initial tension is neglected in curved pipes, the natural frequencies are reduced as flow velocity increases, and the rapid decreases of the natural frequencies took place. However, when the initial tension is taken into account, the natural frequencies are not changed with the change of the flow velocity. In free vibrational simulation of pipe systems, it is necessary to calculate
