Reliability of parts and unrestorable components in the machine design

Introduction. The issues on standardization of reliability indices in the early stages of machine design are considered. This approach maintains thetarget level of reliability when developing parts that are critical in view of stable operation. The work objective is to study design problems in this area. The analysis of the reliability regulation methods suggests that they are insufficient to design. Besides, there are some contradictions associated with the use of the exponential failure law in design.Materials and Methods. At the stage of the task order, the numerical values of the operation time and reliability of the machine are determined. Then the values of the reliability probabilities or failures of the system and its elements are shown by exponential expressions. In them, degrees are the ranking parameters of the system reliability indices.Research Results. The alternative approach to normalization is synthesized; it enables to complete a full structural analysis...
