机电装备的失效事故常常造成巨大的财产损失和环境污染,有的甚至造成人员伤亡,产生严重的社会影响。通过失效分析可以准确地确定失效模式,查明失效原因和机理,并提出相应的预防和改进措施,避免同类事故的再次发生。失效分析过程需要进行各种理化性能测试。理化检验为失效模式的确定、失效原因和机理的判断提供了有力的技术支持,是开展失效分析工作的重要手段。失效分析是一个复杂的技术过程。特别是一个大系统的失效,其工况条件复杂,可疑点众多,技术难度很大。正确的失效分析思路和程序可以帮助失效分析人员快速、科学和公正地查明失效原因和机理,因此,从事失效分析工作的科技人员要具有很高的素质和水平。失效分析科技工作者除了应掌握扎实的基础理论知识外, Failure of electrical and mechanical equipment often causes huge property damage and environmental pollution, and some even cause personal injury and death, resulting in serious social impact. Failure analysis can accurately determine the failure mode, identify the cause and mechanism of failure, and propose appropriate preventive and corrective measures to prevent the recurrence of similar incidents. Failure analysis process requires a variety of physical and chemical properties of the test. Physical and chemical tests provide powerful technical support for the determination of failure mode, failure reason and mechanism judgment, and are an important means to carry out failure analysis. Failure analysis is a complex technical process. In particular, the failure of a large system, the conditions of its complex conditions, many suspicious points, technical difficulty is great. Correct failure analysis ideas and procedures can help the failure analyst quickly and scientifically and fairly find out the cause and mechanism of the failure. Therefore, the scientific and technical personnel engaged in the failure analysis must have high quality and level. Failure analysis In addition to scientific and technological workers should have a solid foundation of theoretical knowledge,
