Problems solved by technology

However, this method is very sensitive to the initial value, and it cannot always complete the evaluation task of the external action width of the square groove stably.
[0008] To sum up, there is still a lack of a stable, fast, and simple method for evaluating the in vitro action width of square grooves.

Abstract

The invention belongs to the field of precision metering and computer application, and particularly relates to a stable and rapid square groove body external effect width evaluation method with the simple mode. The method comprises the following steps of 1, obtaining a measuring point set, and building a feature row vector set, a boundary element set and a status element set according to the measuring point set; 2, obtaining a measuring point corresponding to the minimum value of the status element set as a key point, and adding a measuring point serial number into the key point set; 3, building an analysis matrix and an analysis column vector according to the key point set; 4, performing rank analysis on the analysis matrix and an augmentation analysis matrix so as to determine continuousoptimizing, key point removal and application termination and obtain the optimal value; 5, solving the analysis matrix and the analysis column vector to obtain the optimizing direction; 6, solving anovel key point on the basis of a pursuit problem, updating the measuring point status set, and performing a next circulation; 7, terminating an application and obtaining the optimal value.

Description

technical field [0001] The invention belongs to the field of precision measurement and computer application, and relates to a stable, rapid and simple method for evaluating the external action width of a square tank, which can be used for evaluating the external action width of a square tank and provides guidance for the improvement of its processing technology. Background technique [0002] Dimensional error and shape error (abbreviation of shape error and position error) directly affect product quality, assembly and service life. It is of great significance to quickly and accurately calculate part error. The external action width of the square tank refers to the maximum distance between two parallel planes that are in contact with the two parallel sides of the square tank respectively, as shown in the attached figure 1 shown. At present, the evaluation method of the external action width of the square tank is a research hotspot in the academic circle, which is mainly divi...
