摘要
导管架平台在长期服役过程中受海洋环境载荷及各种操作工况的影响,平台可能发生不同种类的结构损伤。因此,对吊管架平台进行结构健康状态监测对保障平台作业安全具有重要的工程意义。将振动检测技术应用到导管架海洋平台上部组块结构损伤实时监测中,提出基于振动检测数据和有限元分析相结合的平台结构健康评定方法,并通过在东海某导管架平台上的应用试验研究,验证了振动检测技术在导管架平台结构健康监测上的适用性。
In a long service process, the jacket platform is affected by environmental load and various kinds of operations,and different kinds of damage may occur in the structure.Therefore,it is very important to carry out structural health monitoring to ensure the operation safety of the platform.In this paper,the vibration detection technology was applied to the real-time monitoring of the structural damage.A structural health assessment method based on the combination of detection data and finite element analysis was proposed.The applicability of vibration detection technology to the structural health monitoring of jacket platform was verified through the application test on the jacket platform.
