Problems solved by technology

[0031] In order to overcome the existing maintainability allocation methods at home and abroad, the maintainability index is assigned according to the failure rate of the product, and the failure rate of the product is not directly related to the maintenance time. There are products that are easy to repair and have a long average repair time, and products that are not easy to repair The shortcoming of short average repair time, the present invention proposes a value assignment method for factors affecting the average repair time of the aircraft braking system

Embodiment Construction

[0088] In this embodiment, the influence value of various factors affecting the average repair time of the aircraft braking system is assigned. The brake system is composed of 8 products including brake valve, servo valve, solenoid valve, quantizer, wheel speed sensor, control box, switching valve, and emergency air brake valve. The braking system has the function of take-off line braking, output pressure 18MPa; landing anti-skid braking function, output pressure 14MPa; ground turning differential braking function, output pressure 4MPa; ground parking braking function, output pressure 10MPa; emergency braking function, output pressure 9MPa . When any function of the brake system mentioned in the development requirements fails to meet the requirements, it needs to be repaired, and the average repair time is not more than 120min.

[0089] Step 1. Determine the assignment requirements for factors that affect the average repair time of the aircraft braking system

Abstract

A method for assigning values ​​to factors that affect the average repair time of aircraft braking systems, aiming at the accessibility limitation of aircraft maintenance space, space limitation, the number of nozzles and electrical connectors, the number of connecting screws, the number of connecting wires, the weight of products, and safety factors. The impact of restrictions on the maintenance time is represented by a numerical value. The larger the value, the greater the influence on the maintenance time and the longer the maintenance time. The present invention theoretically solves the problem of quantifying the influence of factors affecting the average repair time, and improves the calculation accuracy of the average repair time.

Description

technical field [0001] The invention relates to the field of maintainability of aircraft braking systems, in particular to a method for assigning values ​​to factors affecting the average repair time of aircraft braking systems. Background technique [0002] GJB451A's definition of mean repair time is: "A basic parameter of product maintainability, which is a design parameter. Its measurement method is: under specified conditions and within a specified time, the product is at the specified maintenance level, The ratio of the total time of corrective maintenance to the total number of faults of the repaired products at this level.” Aircraft are classified into three levels: field level, intermediate level, and base level, and the maintenance of brake system products is also the same. The maintenance work that the maintenance personnel can complete at the use site; the intermediate-level maintenance refers to the maintenance work that can be completed by the civil aviation rep...
