Knowledge engineering-based self-adaptive ship profile end cutting model establishment method

Abstract

The invention discloses a knowledge engineering-based self-adaptive ship profile end cutting model establishment method. The method comprises the following steps of 1) establishing an end cutting basic type library; 2) according to the basic type of end cutting, establishing an end cutting design universal template of each type; 3) performing parameter assignment on the ship profile by utilizing knowledge engineering rules; and 4) warehousing and calling the end cutting model. According to the method, the design logic is matched from the design rule, and the method has the self-adaptive characteristic, so that the design efficiency is improved.

Description

technical field

[0001] The invention relates to a ship digital design technology, in particular to a knowledge engineering-based self-adaptive ship profile end-cutting model establishment method. Background technique

[0002] Profile end cutting is a commonly used method for the end of profiles in ships. It is mainly used for the ends of flat steel, bulb flat steel, T profiles and angle steel. In the process of three-dimensional ship design, end cutting is one of the typical characteristics of profiles. , almost covering most of the profile models. There are two conventional processing methods for the end cutting of profiles. One is parameter table drive. The working principle is to first mark each profile of the profile specially, control the length and angle of the specified position through fixed parameters, and then restore the end through basic elements. Basic style of cut. The second method is to use the parametric method to directly complete the modeling of the nega...
