机械工业的任务,是按国民经济各部门提出的要求,提供技术先进、经久耐用、安全可靠的机械产品然而,由于每一种机械设备都经历过开发规划、设计、选材、加工制造、装配、包装、贮存、运输、安装、试运行、使用和维修等复杂的过程,而每一过程中所产生的任何差错、偏差、缺陷和损伤,都可能构成促使机械设备失效的隐患。因此,机械设备始终存在失效的危险,在技术上要求机械产品达到100％的可靠性是不可能的。为了防止或延缓机械产品的失效,提高机械产品的使用寿命和可靠性,一定要重视对机械产品失效的分析和研究工作。失效分析是提高质量和可靠性的一个重要环节。
The task of the machinery industry is to provide advanced, durable, safe and reliable mechanical products according to the requirements of various departments of the national economy. However, since each type of machinery and equipment has undergone development planning, design, material selection, manufacturing, assembling, Packaging, storage, transportation, installation, commissioning, use and maintenance of complex processes, and any errors, deviations, defects and injuries in each process may constitute a hidden danger to the failure of machinery and equipment. Therefore, machinery and equipment always have the risk of failure, the technical requirements of mechanical products to achieve 100% reliability is impossible. In order to prevent or delay the failure of mechanical products and improve the service life and reliability of mechanical products, we must pay attention to the analysis and research on the failure of mechanical products. Failure analysis is an important part of improving quality and reliability.
