Comprehensive analysis method for maintainability of radar structure

Abstract

The invention discloses a comprehensive analysis method for maintainability of the radar structure. The comprehensive analysis method includes the following steps of firstly, determining types and the number of maintenance events and maintenance operation; secondly, determining maintenance schemes and fault rate of a component module; thirdly, virtually simulating during maintenance, and computing a quantized value of a single influencing factor of the maintenance events; fourthly, computing a quantized value of a single influencing factor of the radar structure; fifthly, determining a comment set and computing factor fuzzy evaluation matrix of a mechanism system/component module of the radar structure; and sixthly, computing maintainability fuzzy evaluation matrix of the mechanism system/component module of the radar structure. The comprehensive analysis method has the advantages that by simulating maintenance and determining maintainability influencing fact quantizing method, maintainability design of the radar structure is qualitatively and quantitatively analyzed and evaluated, weak links of the maintainability design are analyzed to instruct improvement of the design, and an accurate and objective maintainability evaluation method is provided for research stage of construction schemes of the ground elevation maneuvering radar structure.

Description

technical field [0001] The invention belongs to the field of maintainability design, and is an evaluation method for radar structure maintainability design in the engineering development stage. Background technique [0002] Maintainability evaluation generally refers to the experiment and evaluation work carried out to determine the maintainability of products under actual use, maintenance and support conditions, including qualitative evaluation and quantitative evaluation. Traditional ground high mobility radar structure maintainability evaluation is completed by performing actual maintenance operations or demonstrations of maintenance operations on maintainable physical prototypes or the product itself, but in the engineering development stage, it is impossible to carry out on the physical prototype or the product itself Maintenance operations, and because of the high cost, it is also difficult to popularize. The present invention takes the ground high-mobility radar stru...

Problems solved by technology

[0005] Since there are great differences among the basic maintenance operations, and the time of different basic maintenance operations varies greatly, the accessibility coefficient expressed by the number of basic maintenance operations cannot accurately reflect the quality of disassembly accessibility.

The disassembly cost V is obtained by the maintainability designers and maintenance experts based on the volume, weight, disassembly tools and equipment, and disassembly methods of the component modules and connectors, and is highly dependent on the experience of designers and maintenance personnel.

In terms of visibility, the literature [1, 4, 5] proposed that there are currently methods such as establishing a visual cone and quantifying a certain maintenance action according to the maintenance object being in the human
