The Method of Parts Selection of rngru Position Marker Based on Synthetic Gray Relational Sequence

Abstract

The invention discloses a method for selecting parts and components of an RNGRU position marker based on a comprehensive gray relational sequence model. The method includes the following steps: Ⅰ. Construction of a comprehensive gray relational sequence model; Ⅱ. Alignment of the position marker based on the comprehensive gray relational sequence model Correlation analysis of assembly parameters is carried out to find out the key assembly parameters for the selection of gyro rotor and drift adjustment screw; Ⅲ. Construct the RNGRU selection prediction model, take the key assembly parameters as the input of RNGRU, and the quality of drift adjustment screw as the output, adjust The regression prediction of the quality of the drift screw, and the matching of the gyro rotor and the drift adjustment screw are completed. The method disclosed in the present invention realizes the precise matching of the gyro rotor and the drift adjustment screw, improves the success rate of assembly of the parts of the position marker, reduces invalid assembly, avoids repeated assembly, disassembly and adjustment, and effectively improves assembly efficiency and reduces assembly cost.

Description

technical field [0001] The invention relates to a matching method, in particular to a method for matching parts of an RNGRU position marker based on a comprehensive gray relational sequence model. Background technique [0002] Assembling is a key link in the development process of the marker, and the assembly quality of the marker directly determines its assembly performance. Drift performance is a key assembly performance of the position marker, which directly affects the guidance accuracy of the guided weapon. In the assembly of the indexer, the drift performance of the indexer can be improved by selecting suitable parts and assembling them together. However, in the actual assembly of the position marker, due to the large number of assembly parameters of the parts of the position marker, the selection of parts is also affected by the assembly parameters, but the degree of influence is still unknown. It is a typical gray system, which makes the selection of parts once The...

However, in the actual assembly of the position marker, due to the large number of assembly parameters of the parts of the position marker, the selection of parts is also affected by the assembly parameters, but the degree of influence is still unknown. It is a typical gray system, which makes the selection of parts once The matching success rate is low, and it often requires repeated assembly, disassembly, matching and debugging to make the drift performance meet the standard, which not only affects the efficiency of assembly, but also easily reduces the assembly accuracy of the position marker
