Problems solved by technology

This evaluation process often takes a lot of time, and the evaluation results are lagging, which cannot realize real-time evaluation and directly affects the production cost of the enterprise; and the evaluation results are usually given by technicians, which are greatly affected by subjective factors, and cannot obtain manufacturing quality. Quantitative results
[0003] In addition, there are many items that need to be tested in the process of evaluating the quality of truss manufacturing, and it is necessary to highlight the impact of measurement items that have a greater impact on quality

Embodiment

[0046] like figure 1 As shown, the real-time quantifiable evaluation method of truss manufacturing quality specifically includes the following steps:

[0047] 1. Determine the test content: determine the specific test content according to the test technical documents; consult the test technical documents to obtain the specified allowable error; consult the design documents to determine the design requirements for each test content. The testing items are the thickness of the truss structure chord (web), the plane size of the truss structure chord (web), the deformation of the truss structure nodes, and the size of the truss structure weld; Nodes shall be determined according to the inspection technical documents;

[0048] 2. Input design data: input the design data of the content to be tested and the allowable error stipulated in the inspection technical documents and specifications;

[0049] 3. Acquisition of measured data: Use a stereoscopic measurement array composed of mu...

Abstract

The invention discloses a real-time quantifiable evaluation method for truss manufacturing quality. The comprehensive evaluation of truss manufacturing quality is divided into three levels, and a scoring evaluation method is introduced in each level. The main steps include: according to the corresponding inspection technology The document requires determination of specific testing content; acquisition of corresponding design data; collection and processing of testing data; quality evaluation at the bar level; quality evaluation at the level of testing items; and overall testing quality evaluation. The invention has the advantages of simple principle, high efficiency, strong robustness, quantifiable detection results, real-time performance and the like.

Description

technical field [0001] The invention belongs to the field of a real-time evaluation system for truss manufacturing quality, and in particular relates to a comprehensive evaluation method for manufacturing quality. Background technique [0002] In the process of evaluating the quality of truss manufacturing, it is necessary to measure various inspection items. After obtaining the inspection data, it is necessary to give the evaluation results according to the requirements of the corresponding inspection technical documents. This evaluation process often takes a lot of time, and the evaluation results are lagging, which cannot realize real-time evaluation and directly affects the production cost of the enterprise; and the evaluation results are usually given by technicians, which are greatly affected by subjective factors, and cannot obtain manufacturing quality. Quantify results. [0003] In addition, there are many items that need to be tested in the process of evaluating t...
