【摘要】 飞雁滩地区海岸已发生了严重的侵蚀,并已威胁到了正常的生产和生活。因此,本区海岸侵蚀的研究与防护工作已迫在眉睫。本课题主要通过物模实验和工程实验对泥沙起动装置的积沙效果进行了检验,并测量了海况参数。本文基于波浪、海流和锚泊系统的动力分析理论和有限元理论,以有限元分析软件ANSYS为平台,采用ANSYS有限元动力分析的原理、方法及过程,从滩海泥沙起动装置的结构特点及其在海上作业时受到海洋动力载荷作用的特点出发,分析了泥沙起动装置的结构动力分析体系和动力方程,并且研究泥沙起动装置在波流载荷作用及其锚链约束下的动力响应特性。通过计算,得出泥沙起动装置的应力和变形,同时设计了两套泥沙起动装置方案。更多还原

【Abstract】 The coast of the Feiyantan oilfield has been corroded seriously, and the normal production and the life in this oilfield have been threatening. So the research and the defending tasks of the erosion in this sea field are staring us in the face. The activation effection of the sediment threshold motion equipment is good. This thesis is based on wave, current and mooring system dynamic theory and finite element theory, and utilized software platform of ANSYS. By use of the principle, method and process of the finite element dynamic analysis of ANSYS, structural dynamic analyzing system and dynamic equation based on structural characteristic of Sediment threshold motion equipment and ocean dynamic load acting on the equipment are studied in this paper, and analyze the dynamic response feature of the equipment under wave and current loads and restriction load caused by the anchor chain. On the base of the calculation solution, the stress of the equipment is in the range of the allowable stress, it meets the strength requirement. Here I designed the other two methods of the sediment threshold motion equipment.更多还原
