Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] The invention provides a method for analyzing the symbolic quality characteristics of electromechanical products and tracing back the causes of failures, such as figure 1 shown, including the following steps:

[0029] S1. Analyze the influencing factors of the formation of product quality, and establish a genetic model of quality characteristics.

[0030] Based on the genetic model of quality characteristics, fully consider the influence of operators, machinery and equipment, raw materials, processing technology, environment and measurement factors on the product manufacturing process (product quality formation process). In electromechanical products, the machining process of shaft parts is common, and the quality of such parts is formed in the process of forming them. In the embodiment of the present invention, the processing of a certain axis ...

Abstract

The invention discloses a mechanical and electrical product symbolic quality characteristic analysis and fault cause tracing method, takes a quality formation process of mechanical and electrical products as a breakthrough point, considers influence of operator, machine, material, the processing process, the environment and measurement (5M1E) factors on quality characteristics in particular and establishes a product quality characteristic gene model based on product quality characteristic influence factors. According to model input requirements, evaluation data of different product fault analysis personnel for fault products is collected, binary transcription of a quality characteristic influence degree is carried out according to an importance threshold, and a symbolic expression of a quality characteristic gene of the fault products is formed; based on the similarity principle, analysis on similarities between the fault product quality characteristic gene and gene database existing quality characteristic genes is developed, and necessary information support is provided for fault cause investigation and fault source tracking; lastly, through diagnosis analysis, causes of product faults are acquired.

Description

technical field [0001] The invention belongs to the technical field of mechanical and electrical product quality analysis and fault cause tracing, and specifically relates to the design of a method for analyzing symbolic quality characteristics of mechanical and electrical products and fault cause tracing. Background technique [0002] The quality of products, especially the quality of mechanical and electrical products, is formed during the processing and manufacturing process of products, that is, the quality characteristics of products are solidified into products as they are processed and shaped. The quality of mechanical and electrical products is mainly affected by 5M1E factors (operator, machine equipment, raw materials, processing technology, environment and measurement). Among them, the operator often has a great influence on the formation of product quality characteristics due to personal habits, skills, age and work experience. Mechanical equipment (such as machi...
