Problems solved by technology
In addition, in the pipeline mechanical analysis, due to the deviation between the design of the valve and the actual processed and manufactured products, the upgrade and change of the valve are more frequent, and a certain type of valve may appear in many pipeline packages of different systems, so if a certain One type of valve is upgraded, and the corresponding piping package needs to be upgraded, and the workload is also very large.
In addition to valves, other types of upstream professional input information will inevitably appear multiple upgrades in the design-improvement-design process, resulting in a significant increase in the workload of the most downstream pipeline mechanics analysis
[0003] To sum up, as the most downstream specialty of pipeline design in nuclear power plants, the specialty of pipeline mechanics analysis has upstream the specialty of layout that provides pipeline axonometric drawings, the specialty of system that provides pipeline operating temperature and pressure, the specialty of structure that provides seismic loads, and the specialty of valve information. The majors of equipment, etc., determine that there are many interfaces for mechanics majors, and the degree of automation in the data transmission process is low, which eventually leads to a large amount of piping calculation work in the process of piping design-improvement-design, and the compilation and review personnel will spend a lot of time. Time to repeat simple tasks, the efficiency is extremely low

Description
technical field [0001] The invention relates to an automatic pre-processing and post-processing platform for nuclear power plant pipeline analysis, which is mainly used in the pre-processing and post-processing processes of CAP series third-generation nuclear power plant pipeline mechanics calculation. Background technique [0002] There are more than 700 nuclear and non-nuclear piping packages in the third-generation passive pressurized water nuclear power plants of the CAP series that require mechanical analysis. Pipeline mechanical analysis calculations need to write fre finite element model file codes, and use Pipestress software for calculations. Main process: Firstly, a preliminary geometric model is established according to the axonometric (ISO) drawing of the piping layout. The ISO diagram contains not only pipes, but also a large number of pipe components such as flanges, wall-piercing parts, valves, and tees, and their standard information. The specific physical p...
