【摘要】：压力容器是十分重要的工业设备,在国民经济和人民日常生活中发挥着重要作用。由于压力容器工作时承受介质压力,具有爆炸的危险性,工作环境恶劣,往往承受高温、高压和化学腐蚀作用,一旦发生爆炸和泄漏就会造成重大的生态灾难,因此各国政府对压力容器的安全运行均十分关注,国际上针对压力容器也制订了不同的检测和评估标准,同时各种新型无损检测技术也被不断应用于压力容器检测与评估中。金属磁记忆检测是近年来出现的一种新型无损检测技术,因其对微小缺陷和应力集中敏感而引起人们的广泛兴趣。本论文尝试将磁记忆无损检测技术应用于压力容器检测中,通过针对压力容器用钢的一些典型承载实验,证明磁记忆检测技术在压力容器评估中的有效性和可行性,同时根据该技术在压力容器应用中的实际需求,重点研究压力容器磁记忆检测中的数据库编制和管理系统技术,以更好适应该技术的实际应用和推广。论文对磁记忆检测技术近年来的一些发展概况进行了评述,并分析了这项技术的发展前景和在压力容器检测中的实际可行性。在此基础上对压力容器磁记忆检测数据管理系统进行了总体方案设计,对压力容器检测中所需要的磁记忆检测数据进行了分析,基于Access小型数据库软件构建了数据库管理系统,利用Visual C++编制了磁记忆检测信号的采集与分析模块；并设计了应力分析、缺陷表征和计算等模块；软件总体上力求做到人机友好性强,易于操作等优点；希望通过论文的研究,使金属磁记忆检测技术在压力容器检测领域得到进一步的推广,同时使缺乏对磁记忆检测技术了解的技术人员能够利用该系统软件进行压力容器的检测评定操作。通过上述工作,初步构建了压力容器磁记忆检测数据管理系统,实现了论文工作的预期目标。
[Abstract]:Pressure vessel is a very important industrial equipment, which plays an important role in national economy and people's daily life. High pressure and chemical corrosion, once explosion and leakage will cause a major ecological disaster, so governments are very concerned about the safe operation of pressure vessels, the international pressure vessels have also developed different testing and evaluation standards, At the same time, a variety of new non-destructive testing techniques have been continuously used in pressure vessel testing and evaluation. Metal magnetic memory testing is a new kind of nondestructive testing technology, which has attracted wide interest because of its sensitivity to microdefects and stress concentration. This paper attempts to apply magnetic memory nondestructive testing technology to pressure vessel testing. The validity and feasibility of magnetic memory testing technology in pressure vessel evaluation are proved through some typical load bearing experiments on steel used in pressure vessel. Meanwhile, according to the actual demand of the technology in pressure vessel application, In order to adapt to the practical application and popularization of the technology, the database compilation and management system technology of pressure vessel magnetic memory detection is studied emphatically. In this paper, the recent development of magnetic memory detection technology is reviewed. The development prospect of this technology and the practical feasibility in the pressure vessel detection are analyzed. Based on this, the overall scheme design of the data management system for the pressure vessel magnetic memory detection is carried out. Based on the analysis of the magnetic memory data needed in the pressure vessel testing, the database management system is constructed based on the Access small database software, and the acquisition and analysis module of the magnetic memory detection signal is programmed by using Visual C; And designed the stress analysis, defect characterization and calculation module; the software generally strive to achieve strong human-computer friendliness, easy to operate and so on. The technique of metal magnetic memory detection has been further popularized in the field of pressure vessel detection, and the technical personnel who lack understanding of magnetic memory detection technology can use the system software to carry out the testing and evaluation operation of pressure vessel. Through the above work, the data management system of magnetic memory detection for pressure vessel is constructed, and the expected goal of the paper is realized.
