【摘要】：全地面起重机臂架系统构造复杂、工况种类多,传统设计方法不能满足其高精度设计和短周期开发的要求,有限元分析方法已成为这一类臂架结构设计的有效方法。建立模型在此类大型复杂结构多种工况有限元分析中是最基本的部分,全地面起重机臂架的复杂构造和多工况分析导致其有限元分析建模的种类繁多和复杂。为了快速而准确地对全地面起重机臂架结构进行开发设计,本文对其基于面向对象编程的快速建模方法进行了研究。本文提出一种采用面向对象编程技术的复杂组合臂架结构模块化编程建模方法,并基于此方法形成了全地面起重机臂架结构有限分析系统,实现了臂架结构的单工况分析、全工况批量分析和输出相应的分析报告。采用这一方法,对臂架结构的承载能力进行了反演计算,并基于VBA宏编写相应模块、形成了全地面起重机作业性能表输出程序。本文研究的主要内容包括以下3个方面:(1)基于面向对象的臂架系统模块化编程,针对全地面起重机臂架系统的各部件结构,利用VisualBasic的面向对象编程技术编写类模块,对臂架结构部件的数据进行封装,将臂架结构部件进行装配,完成各种组合的臂架结构的建模。(2)基于有限元分析平台的结构分析技术,利用ANSYS软件的二次开发技术,将封装的臂架模型数据写入分析命令流中,实现参数化建模、批量分析功能。(3)基于办公自动化技术的报告生成,利用Word文档的VBA技术,将分析结果数据提取,然后输入到文档中生成便于工程技术人员和操作人员使用的计算报告和性能表。将本文方法的分析结果和真实结构实测数据进行对比,可以证明本文提出的设计方法具备可行性。本文所提出的方法将成为全地面起重机臂架结构的快速准确设计的可靠的高效设计方法。
[Abstract]:The jib system of all-ground crane has complex structure and many kinds of working conditions. The traditional design method can not meet the requirements of high-precision design and short-period development. The finite element analysis method has become an effective method for the design of this kind of boom structure, and the establishment of the model is the most basic part in the finite element analysis of this kind of large and complex structures under various working conditions. The complex structure and multi-condition analysis of the boom of all-ground crane lead to the variety and complexity of finite element analysis and modeling. In order to develop and design the boom structure of all-ground crane quickly and accurately. In this paper, the fast modeling method based on object-oriented programming is studied, and a modular programming modeling method for complex composite boom structures is proposed. Based on this method, a finite analysis system for the jib structure of all-ground crane is formed, which realizes the single-condition analysis of the jib structure, the batch analysis of the whole working condition and the corresponding analysis report. The method is adopted. The bearing capacity of the arm structure is inversed and the corresponding module is compiled based on the VBA macro. The main contents of this paper include the following three aspects: 1) Modular programming based on Object-Oriented Boom system. According to the structure of all parts of the whole floor crane jib system, the object oriented programming technology of VisualBasic is used to compile the class module to encapsulate the data of the arm structure parts. The jib structural components are assembled to complete the modeling of various combinations. 2) based on the structure analysis technology of finite element analysis platform, the secondary development technology of ANSYS software is used. The encapsulated jib model data is written into the analysis command stream to realize parameterized modeling and batch analysis function. The report generation is based on the office automation technology and the VBA technology of Word document is used. The analysis result data is extracted, then input into the document to generate the calculation report and performance table, which is convenient for engineers and operators to use. The analysis results of this method are compared with the real structure measured data. It can be proved that the design method proposed in this paper is feasible, and the method proposed in this paper will be a reliable and efficient design method for the quick and accurate design of the boom structure of all-ground crane.
