Embodiment 1

[0053] A kind of specific implementation steps of the method for judging the flame path point of water and fire bending plate based on naive Bayesian classifier comprises the following steps:

[0054] (1) Determine the influencing factors of flame path point selection;

[0055](2) Process sample data and remove noise sample points;

[0056] (3) Calculate the similarity, prior probability and evidence factor required by the naive Bayesian classifier through the filtered sample data;

[0057] (4) Use the Naive Bayesian classifier to judge the points on the curved plate.

[0058] In step (1), according to the effect of different ship boards to be fired and the characteristics of steel materials, five influencing factors that will have a major impact on the shape of the fired board are selected: flame path length, heating time, heating temperature, water and fire distance, cooling Way.

[0059] In step (2), the five main forming influencing factors of qualified panels and unqua...

Abstract

The invention discloses a naive Bayes classifier based line heating flame channel point determination method. The method is mainly applied to the line heating technology based hull plate overall bending forming process of the shipbuilding industry. The method comprises the steps of a. selecting flame channel point impact factors; b. processing sample data and filtering noise factors; c. calculating the classifier required similarity, prior probability and evidence factors through the sample data; d. determining points on bent plates through a naive Bayes classifier. According to the method, classification determination is performed on line heating firing points through the artificial intelligent classifier, so that whether the firing points are flame channel points can be determined effectively, and generation of flame channels is well assisted.

Description

technical field [0001] The invention relates to the technical field of water and fire bending plates, in particular to a method for judging the flame path point of a water and fire bending plate based on a naive Bayesian classifier. Background technique [0002] Water-fire bending, also known as line heating or line heat of forming, is a forming process that utilizes the local thermoelastic-plastic deformation of the metal plate after being locally heated and cooled at a high temperature to achieve overall bending. The water-fire bending plate forming process originated in Japan in the 1950s and 1960s. Due to the advantages of fast processing, flexible operation, no need for other equipment, and suitable for forming complex shapes, it has been rapidly and widely used in shipyards around the world. It has become the main processing method for double curvature outer plates. At present, almost all double-curvature hull plates are formed by the water-fire bending process. [0...
