文档介绍：金属波纹管论文:金属波纹管虚拟实验系统的开发
【中文摘要】金属波纹管是一种外表面呈波纹状的圆筒形薄壁管件,出现及应用至今己经有了一百多年的历史。随着现代工业和科学技术的发展,金属波纹管应用领域不断的扩大,并日渐成为一种重要器件。金属波纹管应用至今,其技术标准几近完善,产品质量也有很大提高,但高速发展的现代化工业对金属波纹管的技术标准及质量提出了的更高的要求。传统金属波纹管在设计研发阶段存在着研发周期长、试验样件多等诸多时间和材料浪费的问题,缩短金属波纹管产品研发周期与提高其工艺水平也就成为当前研究的热点,因此对金属波纹管设计的可靠性及其效率的研究具有重要意义。本文针对传统金属波纹管设计研发效率低的弊端,引用虚拟设计理念,在Ansys软件平台上运用VC++编程语言进行二次开发,建立金属波纹管的虚拟实验系统。该虚拟实验系统能够自动化的完成虚拟实验的工作流程,提取分析中所需的结果,对其是否满足工作特性进行判断。利用初步建立的金属波纹管虚拟实验系统对金属波纹管进行自动化的可靠性分析。将其可靠性分析分为刚度、平面失稳、柱状失稳、疲劳四个部分,分别对其进行虚拟实验分析,并将虚拟实验分析得到的结果与实际中的试验结果进行比较,通过对Ansys分析中的参数设置进行调整来提高此系统的分析精度。

nology, the applications of metalbellows continue to expand, and it is ing an important device. So far, thetechnical standards almost perfect, the product quality has been improved greatly, but therapid development of modern industrial put forward higher requirements on the technicalstandards and quality of the metal bellows. Traditional design and development phase ofmetal bellows has many of disadvantage: the long development cycle and a large numberof test sample which makes a lot of time and material wasted, so how to short the productdevelopment cycle of metal bellows and improve the level of technology has e ahot to
