机械装置的可靠性结构框图又称为可靠性逻辑图,它与可靠性的数学模型一样,在可靠性技术中有着十分重要的意义,是可靠性预测和可靠度分配的基础。可靠性结构框图是表示整个系统中各元(部)件之间的功能关系,以及这些功能对整个系统的工作影响。了解这种关系是系统可靠工作的先决条件。如果不知道每个元(部)件的功能关系以及这些功能对整个系统的影响,就不可能提高系统的可靠性,也无法通过各个元(部)件的可靠性指标,计算出整个系统的可靠性指标。因此,精确地描述这种功能关系是
The mechanical structure of the reliability of the block diagram, also known as the reliability of the logic diagram, which, like the reliability of the mathematical model, has great significance in the reliability of technology, reliability prediction and reliability distribution foundation. The reliability block diagram shows the functional relationships among the elements in the entire system and their impact on the overall system. Understanding this relationship is a prerequisite for the reliable work of the system. If you do not know the functional relationship of each element and the impact of these functions on the entire system, it is impossible to improve the reliability of the system, nor can you calculate the reliability of the entire system Reliability indicators. Therefore, to accurately describe this functional relationship is
