基于ANSYS的煤气罐壁厚的研究 [摘要]有限元法是一种离散化的方法来描述数学表述中的连续体问题。它是随着电子计算机的发展而迅速发展起来的一种现代计算法，ANSYS已经成为机械及压力容器行业分析软件的主流,近十年来,ANSYS软件在压力容器行业发挥着巨大作用，成为压力容器分析设计事实上的标准。有用ANSYS有限元软件对煤气罐进行优化设计，摒弃了传统结构设计的被动校核方法，进而在可行域内寻求最佳方案，很大程度上减少了设计成本和周期，试产品设。研究结果与实际情况是相吻合的。综合上述分析，有限元模型的建立、分析结果是客观的，较为真实地反映了压力容器管板的受力情况。经分析发现,ANSYS软件分析的结果与真实情况基本一致。整个建模、分析过程充分说明ANSYS软件为压力容器的结构设计提供了可靠、高效的理论依据。[关键词]煤气罐; ANSYS;有限元;应力分析;优化设计Study of the wall thickness of the gas tank based on ANSYS LUO YONG (Grade 08, Class4,Major:, Machine design manufacturing and automation，Shaanxi University of Technology,Hanong,723003,Shaanxi）Tutor:Peng ChunLei Abstract ：The finite element method is a kind of method that is long-lost to turn to describe the continuous body problem in mathematics description. It is a kind of modern calculation method that quickly develops with the development of computer, ANSYS has become machinery and pressure vessel industry analysis software mainstream, in the last ten years, software ANSYS in pressure vessel industry has played an important role, become pressure vessel design analysis of the standard. In fact, with ANSYS finite element software to optimize design gas tank, rejected traditional structure design of the passive checking method, then in the feasible region seek the best solutions, to a great extent, reduce the cost and design cycle, try a product. Research results and actual situation is in line. A combination of the analysis, finite element model, the analysis results is objective, more genuine reflect the pressure vessel tube plate stress.. After analysis discovery, ANSYS software analysis result with real situation basic consistent. The entire modeling, the parsing process showed fully the ANSYS software has provided reliably, the highly effective theory basis for pressure vessels structural design. Key words: the natural gas tank; ANSYS; finite element; stress analysis; optimization design 目 录 1前言 1 1.1煤气罐简介 1 1.2有限元计算软件ANSYS的介绍 2 1.3优化设计简介 5 1.3.1优化设计
