Abstract

The invention belongs to the technical field of equipment design and use, and discloses an equipment accidental damage average repair time measurement method, an evaluation method and application; therepairability probability is represented as the repair degree, and refers to the probability of maintaining or repairing its prescribed state when damaged equipment is repaired according to specifiedprocedures and methods under specified conditions within specified time ; the repair degree t is the probability of completing restoration in time t, and the probability density function is a restoration time density function; the damage repair time is not a constant and exists in a certain statistical distribution form, and the equipment damage repair time obeys logarithmic normal distribution;the repair time parameter of the equipment can be represented by the average repair time MTTRC, and the average time required for recovering to the specified task capability state when repair repair is carried out by using the specified program, method and resource. According to the invention, the equipment repairability level is evaluated, and a foundation is laid for improvement of the repairability design level.

Description

technical field [0001] The invention belongs to the technical field of equipment design and use, and in particular relates to a measurement method, evaluation method and application of the average repair time of equipment accidental damage. Background technique [0002] At present, during the service of equipment, in addition to the normal routine damage caused by the accumulation of service life, accidental damage or unconventional damage will inevitably occur, such as accident damage, combat damage, lightning damage, foreign object damage, etc. impact damage etc. The location and scale of these accidental injuries cannot be accurately predicted. When these accidental damages occur, the equipment needs to be repaired to restore its original intact state or restore it to a certain task-performing state. For example, in the Middle East War in 1973, if the Israeli Air Force's aircraft were not easily repaired after the battle or the army did not have the ability to repair th...
