【摘要】：岸边集装箱桥式起重机是常见的港口装卸集装箱用起重设备，遍布于世界各大港口，是装卸集装箱的主要专用设备。岸桥结构设计在整个岸桥设计过程中占很大比重，，其结构的承载能力是岸桥的主要性能参数。随着工业水平的发展，传统设计方法逐渐的被新兴的现代设计方法所替代，现代设计方法中诸如模块化设计、优化设计、有限元法、参数化设计等逐渐占据主要地位。对于结构设计计算而言，目前主要采用的方法是有限元法，设计者多使用各类有限元计算软件进行结构的各项性能的分析计算。对于岸桥这种大型设备而言，利用有限元软件完成从模型建立、载荷设置到结果后处理等一系列结构分析工作，不仅工作周期较长，而且容易出现这样或那样的问题。由于整个分析过程是设计者与软件直接交互的过程，故对设计者的软件使用能力要求较高，设计分析结果也会因设计人员的经验而有所不同。岸桥结构参数化建模分析通过完成在ANSYS软件中对岸桥结构有限元模型建立的整个过程的封装，实现了结构的参数化分析，并使分析人员只需操作界面简单的第三方软件即可完成复杂的岸桥结构分析过程。对于岸桥结构参数化有限元分析，本文的研究内容主要有： 1）通过对利用有限元软件ANSYS软件的传统结构分析计算方法的汇总，研究岸桥金属结构的有限元分析的整个过程，并通过相关APDL语言的介绍，整理了岸桥结构参数化分析过程中用到的主要命令语句； 2）结合岸桥的结构特点及ANSYS软件的特点，建立能够合理的描述岸桥参数并完成岸桥结构参数化分析的数学模型； 3）研究规范《F.E.M欧洲起重机设计规范》中有关起重机结构设计计算的相关内容，包括载荷及载荷组合的设置、各计算内容的计算准则等，并使用VisualBasic6.0编程软件完成对该部分内容的封装； 4）通过对ANSYS软件APDL语言的研究和积累，并结合VB高级语言的强大功能，实现对结构计算的各方面内容及数据结果的提取分析； 5）利用Visual Basic6.0软件完成参数化建模分析软件的编制，并保证该软件系统满足既定功能、界面简单、操作简便，使一般工程人员均能根据结构数据完成对指定结构类型的岸桥的结构有限元分析。
[Abstract]:Quayside container bridge crane is a common lifting equipment used for loading and unloading containers in ports. It is spread all over the world and is the main special equipment for loading and unloading containers. The design of the quayside bridge structure occupies a large proportion in the whole design process of the quayside bridge, and the bearing capacity of the structure is the main performance parameter of the quayside bridge. With the development of industry, the traditional design methods are gradually replaced by the new modern design methods, such as modular design, optimization design, finite element method, parametric design and so on. For structural design and calculation, the main method is finite element method (FEM), and designers often use all kinds of finite element calculation software to analyze and calculate the performance of the structure. For the large equipment such as quayside bridge, the finite element software is used to complete a series of structural analysis work, such as modeling, load setting and post-processing of the results, which not only has a long working period, but also is prone to one kind of problem or another. Because the whole analysis process is the process of direct interaction between the designer and the software, the designer's ability to use the software is very high, and the result of design analysis will be different from the designer's experience. Parametric modeling analysis of quayside bridge structure by encapsulating the whole process of establishing the finite element model of quayside structure in ANSYS software, the parametric analysis of the structure is realized. So that the analysts can complete the complex analysis process of the quayside bridge structure only by using the third party software with simple interface. For the parametric finite element analysis of quayside bridge structure, the main contents of this paper are as follows: 1) the traditional structural analysis and calculation methods based on the finite element software ANSYS are summarized. The whole process of finite element analysis of the metal structure of the quayside bridge is studied, and the main command statements used in the parameterization analysis of the quayside bridge structure are arranged through the introduction of the related APDL language. 2) combining the structural characteristics of the quayside bridge and the characteristics of the ANSYS software, a mathematical model which can reasonably describe the parameters of the quayside bridge and complete the parameterized analysis of the quayside structure is established. 3) studying the relevant contents of crane structure design calculation in F.E.M European Crane Design Code, including the setting of load and load combination, the calculation criteria of each calculation content, etc. And use VisualBasic6.0 programming software to complete the encapsulation of this part of the content; 4) through the research and accumulation of APDL language of ANSYS software and the powerful function of VB high-level language, we can extract and analyze all aspects of structure calculation and data results. 5) the parameterized modeling and analysis software is compiled by using Visual Basic6.0 software, and the software system meets the established function, the interface is simple and the operation is simple. So that the general engineers can complete the finite element analysis of the quayside bridge of the specified structural type according to the structural data.
