【摘要】： 随着我国石油行业的快速发展,输油管式加热炉的需求量越来越大,用户不仅对其性能要求越来越高,而且要求尽可能缩短研发周期。目前的结构设计和计算主要依靠手工来完成,不仅效率低下而且计算由于做过大量的简化和近似处理而不准确,并且重复工作量大,耗时较多,成本较大,不利于管式加热炉研发制造的可持续发展。 为了解决上述问题,本文在对有限元参数化技术、ANSYS二次开发技术、优化设计技术、VB编程技术深入研究的基础上,提出了管式加热炉钢结构有限元分析及优化设计系统的解决方案。 论文的研究内容包括如下几个方面: (1)对传统设计的加热炉钢结构进行简化,利用APDL建立其参数化有限元模型;分析加热炉的各种载荷工况,在ANSYS环境中计算4000 KW加热炉在等效静力风载荷、吊装载荷工况下强度和刚度的分布情况。 (2)对传统设计的4000 KW加热炉进行模态分析、风载荷及地震载荷动力响应分析,通过分析结果验证加热炉在结构设计上是否能够满足设计要求,并将动力风载与等效静力风载分析结果进行对比。 (3)依据“相对差商法”的思想,开发一种适用于加热炉钢结构的离散变量优化算法,编制相应的优化程序。以传统设计的4000 KW加热炉钢结构为例对其进行优化。 (4)应用VB开发工具将参数化技术、有限元分析方法、优化设计技术融为一体,建立一套管式加热炉钢结构有限元分析及优化设计系统。
[Abstract]:With the rapid development of petroleum industry in China, the demand for tube-type heating furnace is increasing, and users not only require higher and higher performance, but also request to shorten the research and development period as far as possible. At present, the design and calculation of structures are mainly done by hand, which is not only inefficient, but also inaccurate due to a large amount of simplification and approximation, and the repeated workload is large, time-consuming and costly. It is not conducive to the sustainable development of tube furnace R & D and manufacture. In order to solve the above problems, based on the further study of the parameterized finite element technology, ANSYS secondary development technology, optimization design technology, VB programming technology, The solution of finite element analysis and optimization design system for steel structure of tubular heating furnace is presented. The research contents of this paper include the following aspects: (1) simplify the steel structure of the traditional heating furnace and establish its parametric finite element model by APDL; The distribution of strength and stiffness of 4000 KW reheating furnace under equivalent static wind load and hoisting load is calculated in ANSYS environment. (2) the modal analysis, dynamic response analysis of wind load and seismic load of the traditional 4000 KW furnace are carried out. The results show that the furnace can meet the design requirements in structural design. The analysis results of dynamic wind load and equivalent static wind load are compared. (3) according to the idea of "relative difference quotient method", a discrete variable optimization algorithm suitable for heating furnace steel structure is developed, and the corresponding optimization program is worked out. The steel structure of 4000 KW heating furnace is optimized by taking the traditional design as an example. (4) the parameterized technology, the finite element analysis method and the optimization design technology are combined with VB development tools, and a steel structure finite element analysis and optimization design system of the casing heating furnace is established.
