复杂悬跨条件下的管线涡激振动分析(英文)

Spans occur when a pipeline is laid on a rough undulating seabed or when upheaval buckling occurs due to constrained thermal expansion. This not only results in static and dynamic loads on the flowline at span sections, but also generates vortex induced vibration (VIV), which can lead to fatigue issues. The phenomenon, if not predicted and controlled properly, will negatively affect pipeline integrity, leading to expensive remediation and intervention work. Span analysis can be complicated by: long span lengths, a large number of spans caused by a rough seabed, and multi-span interactions. In addition, the complexity can be more onerous and challenging when soil uncertainty, concrete degradation and unknown residual lay tension are considered in the analysis. This paper describes the latest developments and a .state-of-the-art. finite element analysis program that has been developed to simulate the span response of a flowline under complex boundary and loading conditions. Both VIV and direct wave loading are captured in the analysis and the results are sequentially used for the ultimate limit state (ULS) check and fatigue life calculation.     

钢管约束混凝土轴压短柱承载力的研究

传统钢管混凝土是将混凝土直接灌入钢管,然后全截面承压,使得混凝土处于三向受力状态;但这种结构形式及加载方式就决定其并没有最大发挥钢管的高抗拉性能及混凝土的高抗压特性.对此,笔者提出一种钢管约束混凝土受力体系,理论分析证明该体系较传统构件有着更大的承载力.

基于MATLAB的“电力电子技术”仿真实验的研究

电力电子技术是主要研究各种电力电子器件,以及由这些电力电子器件所构成的各种变流电路和变流装置,运用这些变流装置完成对电能的变换和控制。近年来,随着功率变流技术的迅猛发展,经过变流技术处理的电能在整个国民经济的用电量中所占比例越来越大。为了方便地对这些变流电路进行仿真,采用了MATLAB的Simulink库。同时,还采用VISUALBASIC语言将电力电子变流电路的波形与MATLAB仿真界面进行链接,以便更简洁地、直观地,甚至是在无人指导的情况下,让学习者独立地完成电力电子变流电路的仿真实验。

Time-domain simulation for water wave radiation by floating structures （Part A）

Direct time-domain simulation of floating structures has advantages： it can calculate wave pressure fields and forces directly; and it is useful for coupled analysis of floating structures with a mooring system. A time-domain boundary integral equation method is presented to simulate three-dimensional water wave radiation problems. A stable form of the integration free-surface boundary condition （IFBC） is used to update velocity potentials on the free surface. A multi-transmitting formula （MTF） method with an artificial speed is introduced to the artificial radiation boundary （ARB）. The method was applied to simulate a semi-spherical liquefied natural gas （LNG） carrier and a semi-submersible undergoing specified harmonic motion. Numerical parameters such as the form of the ARB, and the time and space discretization related to this method are discussed. It was found that a good agreement can be obtained when artificial speed is between 0.6 and 1.6 times the phase velocity of water waves in the MTF method. A simulation can be done for a long period of time by this method without problems of instability, and the method is also accurate and computationally efficient.

Route design and automatic check in electronic chart display and information system

For an electronic chart display and information system ( ECDIS), the most important function is the route design. In this paper,a novel approach to developing ECDIS was given and then an effective method was proposed for route design and automatic check. The mathematical model and logical relationship for coordinate transformation were also provided. They were adopted in ECDIS developing, which was based on the research of the Vxworks real-time operating system. The actual system application implies that the method is practical and can held navigation verv well.
