Problems solved by technology

[0005] In order to solve the problems existing in the prior art, the present invention provides a screening method for the LRU determined in the equipment design during the product design process. The present invention is based on the definition and connotation of LRU, and through in-depth analysis of the definition and connotation of LRU , considering two factors of failure rate factor and complexity factor, an LRU screening criterion based on the definition and connotation interpretation of LRU is established. LRU planning work lacks normative guidance methods and work guidelines, which is of great significance for guiding product design planning and improving maintainability design

[0049] S102, setting up a failure rate threshold and a complexity threshold, evaluating and calculating the failure rate and the complexity respectively, and obtaining the calculation results of the failure rate factor and the evaluation results of the complexity factor respectively;

[0050] S102, performing screening calculation on the evaluation results of the failure rate factor and the evaluation result of the complexity factor, and confirming whether the LRU to be screened can become an LRU.

[0051] Wherein, the product structure includes the interface quantity and complexity of the LRU struc...

Embodiment 2

[0073] In practical application, the screening steps of the LUR to be screened are as follows, see figure 2 The block diagram of the LRU screening method shown and image 3 The detailed diagram of the LRU screening process shown:

[0074] 1. Analyze the LUR to be screened

[0075] Collect the structural composition of the screened objects, the time required for maintenance and replacement, the maintenance tools required for detection, diagnosis, replacement and adjustment, and the failure rate.

[0076] The structure composition of the screening object is mainly to collect the interface quantity and complexity of the structure.

[0077] The time required for maintenance and replacement of the screening object refers to the time spent by the maintenance personnel in the whole process of detection, replacement and adjustment of the screening object in actual maintenance.

[0078] Screening the maintenance tools of the object includes detecting the type and quantity of the ma...

Abstract

The invention provides an LRU screening method based on definition and connotation interpretation, and relates to the field of product design. The method comprises the steps: obtaining a screening factor of a fault rate factor and a complexity factor through the analysis of the product structure and the product maintainability of a to-be-screened LRU at a product design stage; setting a failure rate threshold value and a complexity threshold value, respectively evaluating and calculating the failure rate and the complexity, and respectively obtaining a calculation result of the failure rate factor and an evaluation result of the complexity factor; and screening and calculating the failure rate factor evaluation result and the complexity factor evaluation result, and determining whether theto-be-screened LRU can become LRUs or not. The current situation that the LRU planning work of the product lacks a normative guidance method and work guidance in the prior art is solved, and the method is of great significance in guiding the design planning of the product and improving the maintainability design.

Description

technical field [0001] The present invention relates to the field of product design, in particular to an LRU division method and device based on definition and connotation interpretation Background technique [0002] Field replaceable unit, also known as field replaceable unit, is defined in GJB / Z91-1997 as: a product and its components that are replaceable in the use environment, that is, in the field or combat environment. [0003] The LRU is designed so that a failed unit can be easily replaced in a real-world environment. That is, when the LRU occurs or is expected to fail, it can be quickly disassembled and replaced with spare parts, so that the equipment can return to the specified technical state, so as to improve the convenience of equipment maintenance in the actual use environment. The use of LRU on equipment can save maintenance time to a large extent, ensure the normal use of equipment, and improve the maintenance efficiency, convenience and economy of equipment...
