Fast, stable and simple method for evaluating width of square key which works in vitro

Abstract

The invention belongs to the field of precision metering and computer application, and relates to a stable and fast method with a simple form for evaluating the width of a square key which works in vitro. The method comprises the steps of step 1, acquiring a measuring point set, and establishing a characteristic row vector set, a boundary element set and a state element set according to the measuring point set; step 2, taking measuring points corresponding to a minimum value of the state element set as a key point, and adding a measuring point sequence number to a key point set; step 3, establishing an analysis matrix according to the key point set and analyzing row vectors; step 4, performing rank analysis on the analysis matrix and an augmented analysis matrix to determine whether to continue to seek optimization, eliminate the key point or terminate a program and obtain an optimal value; step 5, solving the analysis matrix and analyzing the row vectors to obtain an optimization seeking direction; step 6, solving a new key point by following a problem, updating the measuring state set, and entering the next cycle; step 7, terminating the program, 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 width of action outside the body of a square key, which can be used for evaluating the width of action outside the body of a square key 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 a square key refers to the minimum distance between two parallel planes that are in contact with the two parallel sides of the square key, as shown in the attached figure 1 shown. At present, the evaluation method of the width of action of square bonds in vitro is a research hotspot in the academic circle, which is mainly d...

Problems solved by technology

However, this method is very sensitive to the initial value, and it cannot always complete the task of evaluating the width of action of square bonds stably.

[0008] In summary, there is still a lack of a stable, fast, and simple method for evaluating the width of action of square bonds in vitro
