机械设备的可靠性是其灵魂，本文首先阐述了设备可靠性的定义及其基本内涵，又解释了与可靠性密切相关的故障及故障曲线，以及从设备故障曲线中获得的提高设备可靠性其实。接着又介绍了当前可靠性研究中出现的问题，最后在问题中得到了可靠性研究的新方向以及提高机械设备可靠性的若干办法。 The reliability of machinery and equipment is its soul, this paper first describes the definition of equipment reliability and its basic connotation, but also explains the reliability and reliability are closely related to the failure curve and failure curve obtained from the equipment to improve equipment reliability In fact, . Then it introduces the problems in the current reliability research. At last, we get the new direction of the reliability research and some ways to improve the reliability of the mechanical equipment.
