CATIA (Computer-graphics Aided Three-dimensional Interactive Application) three-dimensional model establishing method for railway simple-support bridge

Abstract

The invention relates to a three-dimensional modeling technology and discloses a CATIA (Computer-graphics Aided Three-dimensional Interactive Application) three-dimensional model establishing method for a railway simple-support bridge, for a purpose of improving the design quality and the design efficiency. The CATIA-based three-dimensional model establishing method comprises the following steps: firstly, formulating a data naming rule for completely eradicating number repetition of parts, and carrying out distinct data structure division for a purpose of better design after the strict data naming rule is formulated; then, erecting a framework to provide accurate reference information for subsequence design; then, establishing corresponding parameters and functions and making templates of various parts and various types by using the established framework information, then calling the templates to finish establishment of the model, measuring work amounts and sizes of various parts and hanging information of the work amounts and sizes of various parts under the corresponding templates, and finally finishing two-dimensional drawing output under a CATIA engineering drawing module. The CATIA-based three-dimensional model establishing method is applicable to rapid and accurate establishment of the three-dimensional model of the railway simple-support bridge, and provides a 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,...
