[0046] Specific examples for each of the above steps are as follows:

[0047] A. Define data naming rules;

[0048] For data naming rules, we propose the following data naming principles:

[0049] (1) Make the CATIA file obtain a unique storage identifier (PartNumber, file name);

[0050] (2) Easy to share, identify and use;

[0051] (3) Reduce data redundancy while ensuring design requirements;

[0052] (4) It is convenient for traceability and effective control of versions;

[0053] (5) It is convenient to identify different states of the same component model;

[0054] (6) The name of the document is consistent with the name of the part number (PartNumber);

[0055] (7) The file name is only allowed to contain 26 uppercase English letters, 10 Arabic numerals and a dash "-" in English;

[0056] (8) The structure tree name consists of 33 characters (including 8 dashes "-").

[0057] For the structure tree naming rules, please refer to figure 2 , the interpretation of ...

Abstract

The invention relates to three-dimensional modeling technology, which discloses a CATIA-based method for creating a three-dimensional model of a simply supported bridge for railways, so as to improve design quality and efficiency. The present invention first formulates data naming rules to prevent duplication of part numbers. After having strict data naming rules, a clear data structure division is required for better design; then the skeleton is built to provide accurate reference information for subsequent designs ; Next, use the created skeleton information to create corresponding parameters and functions to produce various types of templates for each part, and then call these templates to complete the model establishment. At the same time, the engineering quantities and dimensions of each part can be measured and hung on the corresponding model Next, finally complete the two-dimensional drawing in the CATIA engineering drawing module. The invention is suitable for fast and accurate creation of a three-dimensional model of simply supported bridges for railways, and provides technical guidance for actual construction.

Description

technical field [0001] The invention relates to a three-dimensional modeling technology, in particular to a method for creating a three-dimensional model of a simply supported bridge for railways based on CATIA. Background technique [0002] Simply supported bridges have the problem of weak earthquake resistance. If they are built on super high piers, they will have problems such as low safety under the action of super external forces. The survey and design is one of the most important links in building a simply supported bridge, and it is the main basis for engineering construction; the design quality and design efficiency are directly related to the quality, safety and benefit of the project. [0003] Traditional two-dimensional design has shortcomings such as low efficiency, low knowledge reusability, and cumbersome design changes. The use of advanced three-dimensional design technology can improve the design quality and efficiency of bridges, optimize the design process,...
