基于振动响应分析的海底管道悬空内检测研究
Study on submarine pipeline suspension internal detection based on vibration response analysis
摘要
Abstract
Submarine pipelines laid in the seabed are often suspended due to natural or man-made factors such as ocean current erosion and ship anchoring,which can easily cause pipeline deformation,corrosion,damage,cracking and leakage,seriously affecting the safety of pipelines.Aiming at the suspension internal detection for DN200 submarine pipelines,an internal detection robot was designed,and its dynamics analysis was conducted.Meanwhile,a flexible pipeline-soil coupling model was established by combining ANSYS and ADAMS software,and the internal detection simulation analysis for suspended pipelines was carried out.The fast Fourier transform and the short-time Fourier transform were used to process the vibration response signal of the internal detection robot under complex excitation coupling conditions,and the effective identification of the suspended pipeline section was realized by analyzing the vibration acceleration of the robot.The research results provide a new idea for the internal detection of oil and gas pipelines in suspension.关键词
