【摘要】 本文从材料强度的观点,分析了石油矿场机械的服役条件和主要失效类型。根据国内外的研完成果和作者从事失效分析工作的经验,总结了失效分析的基本方法和一般程序,并对一些问题进行了讨论。本文强调指出,失效分析的目的不仅在于失效原因的分析和判断,更重要的是反馈到生产实践中去。文中列举了失效分析及反馈的一些实例,对于提高失效抗力与设计、材料、工艺变革的关系,也提出了一些看法。更多还原

【Abstract】 In view of the strength of materials, the operating condition and main failure mode of oil field equipment are analysed in this paper. On the based of achievements in scientific research at home and abroad and his own experience the writer summed up the main method and general process of failure analysis. Some important problems are discussed. Emphasis is placed on that the purpose of failure analysis is not only to find out and judge the reason for failure, but more important is to give the feedback to the production practice. In this paper some examples of failure analysis and its feedback are shown and some views on relations between upgrading failure resistance and improving design, materials and technology are put forward also.更多还原
