The Dynamic Analysis for Large Undersea Pipelines with VE-layer Modeled as Composite Shell.

Chung, Pei-Yin 24 July 2001 (has links)
­^¤åºK­n The research is to investigate the dynamic behavior for the large undersea pipeline structure system subjected to the wave force. In this study, the primary structure is composed of two steel layers and one viscoelastic layer modeled as a three-layered pipeline structure in composite type. The theory of this study is based on Reddy¡¦s¡§High-order Shear Deformation Theory¡¨and continues Lee¡¦s research on VE materials applied in the engineering structures to discuss the dynamic behavior and the ability of VE materials to restrain the vibration. Based on the theory derived, the analytical results of vibration, deformation of the pipeline and the dynamic behavior for the whole pipeline system are obtained and discussed, in order to improve the dynamic performance for pipeline system and eventually to upgrade the durability of the system. This thesis is divided into two parts for pipeline structures ¡X the general pipeline structures and the undersea pipeline structures. For the general pipeline structures, the study focuses on the effect of the vibration mitigation due to the variation of the diameter of pipelines, length of pipelines and thickness of the viscoelastic material. Besides, the external forces of high-frequency loading and low-frequency loading are both applied. For the undersea pipeline structures, the depth of water, loading types (include the in-line force and the lift force), the periods of wave and the wave length of environmental effects are taken into account.
