[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.
