Problems solved by technology

[0004] (1) Every time the pipeline stress analysis model is adjusted, the 3D pipeline model needs to be manually established in the PDMS software, which involves a lot of repetitive work, wastes a lot of time, and greatly affects work efficiency
[0005] (2) In the process of re-establishing and modifying the 3D model, errors are prone to occur and details are easily lost, especially when the piping layout personnel and the 3D modeling personnel are not the same person, it is more likely to lead to low quality of the final design product and error rate high
[0006] (3) Due to the uncontrollability of the process, the data is easily modified and lost after multiple manual transfers, which affects the consistency of stress analysis and 3D model data, which is not conducive to version control and multi-person and multi-professional collaboration
[0007] (4) Due to the cumbersomeness of the process, the complexity of collaborative design for designers, especially designers of various small professions, is obviously increased, and the workload of each professional is increased
[0009] (1) There is a problem that the pipeline stress data file is inconsistent with the 3D model
[0010] (2) The workload of manually filling in the input file of pipeline stress analysis is heavy, and the designer needs to manually fill in th

Description

technical field [0001] The invention relates to a conversion method for integrated data processing of pipeline design in a thermal power plant, in particular to a method for mutual conversion of data between stress analysis and three-dimensional models in pipeline design. Background technique [0002] PDMS (Plant Design Management system) is a three-dimensional layout design management software for factories, which is widely used in engineering design in electric power, chemical industry and other industries. Piping personnel can build detailed three-dimensional pipeline and equipment models on this platform. GLIF is a professional software developed by Northeast Electric Power Design Institute for the stress analysis of power pipes in power plants. It is developed by using structural programming methods and complies with the "Technical Regulations for Stress Calculation of Steam-Water Pipelines in Thermal Power Plants" (DL / T5366-2006). The stress calculation program mainly ...
