可靠性是产品的重要质量指标。产品的可靠性高,就意味着寿命长、故障少、维修费用省。对于重要产品,如航空航天设备、军用武器、电力设备等,其产品的可靠性极为重要。本文通过对机电设备可靠性简史、现状、研究的意义,存在相关问题及对策的论述,指出我们应加强对机械设备的可靠性理论研究。 Reliability is an important quality indicator of the product. The high reliability of the product means long life, less trouble, and less maintenance costs. For important products, such as aerospace equipment, military weapons, electrical equipment, etc., the reliability of their products is extremely important. In this paper, a brief history of mechanical and electrical equipment reliability, status quo, the significance of the study, there are related issues and countermeasures, and pointed out that we should strengthen the theoretical reliability of mechanical equipment.
