金属波纹管虚拟实验系统的开发
|
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。
Metal bellows is cylindrical thin-walled tube with the corrugated outer surface, theemergence and application has already had one hundred years of history. With thedevelopment of modern industry and science and technology, the applications of metalbellows continue to expand, and it is becoming 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 become ahot topic of current researching, therefore, it is important to study on the design reliabilityand efficiency of metal bellows.
In this paper, against the drawbacks of low efficiency in traditional design anddevelopment of metal bellows, the virtual design concept is referenced, using VC++programming language on the Ansys software platform for secondary development, thevirtual experimental system of metal bellows is established. The virtual experimentsystem can complete of the work processes of the virtual experiment automatically andextract the result which is needed in analyzing, at last, the result is judged whether or notto meet the operating characteristics.
The initial established virtual experiment system is used to do the reliability analysisof metal bellows automatically. The reliability analysis is divided into four parts: stiffness,plane instability, columnar instability and fatigue, with respect to their virtualexperimental analysis, and the results is compared between virtual experiment and actualexperiment,the accuracy of the analysis of this system is improved by adjusting theparameter of Ansys analysis.
