Finite-Element Analysis the Vibrancies of Floating Steel-Pipeline on Sea

The vibrancies of floating steel-pipelines on sea was analyzed by the inherent vibrancies character analysis method; a finite-element model was established to simulate the lateral bending vibration of the pipelines by ADINA software, the conclusion was obtained that the lateral bending vibration of pipelines was able to meet with the requirements of pipelines' function on the 4 class sea-conditions.
