Finite Element Modeling and Simulation of Three-core Optical Fiber Composite Submarine Cable Stretching
摘要
Abstract
Three-core optical fiber composite submarine power cable is often stretched in the process of transportation,installa-tion and operation.The stress and strain data can be obtained by the simulation of stretching modeling,which is difficult to be obtained in the entity experiment.In this paper,the finite element model of the submarine cable is established,which is used to simulate the stretching process.We first simplify the structure of the submarine power cable according to the mechanical characteristics of stretching.The constraint,speed loads and hourglass control are then imposed to simulate the axial stretching process.Finally,the stress and strain data of the finite element model is extracted and processed to obtain the stress and strain of the submarine cable.The results provide reference for the study of mechanical properties and operating condition j udgement of the submarine power cable.关键词
