Automatic arrangement and linkage design method of unit rail section of railway seamless line

Abstract

The invention discloses an automatic arrangement and linkage design method for unit rail links of railway jointless tracks. The automatic arrangement and linkage design method includes the following steps: a railway track vertical section user-defined entity is built, a railway jointless track design engineering user-defined dictionary is built, trans-regional rail junction short rails and region rail junction buffering areas are arranged in a batch mode, starting-stopping point mileage and stopping point control modes of the unit rail links of the jointless tracks are set, the jointless track locking rail temperature within each range is checked and calculated, the unit rail links are automatically added for each range, the unit rail link at the tail end of each range is checked and adjusted, the unit rail links are linked and adjusted interactively, a unit rail link design achievement is checked and prompted, a unit rail link arrangement table and a unit rail link number table are generated, and a jointless track arrangement diagram is generated. The automatic arrangement and linkage design method is suitable for designing the unit link arrangement of the single-track and double-track railway regional and trans-regional jointless tracks, and the unit link arrangement within the ranges can be automatically completed in a batch mode; when the unit links are interactively edited, updating of the follow-up unit links is automatically completed, the automation degree is high, the practicability is high, the designing efficiency and the achievement quality can be greatly improved, and the obvious application and popularization value can be achieved.

Description

technical field [0001] The invention relates to a design method of a seamless railway line, in particular to a method for automatic layout and linkage design of unit rail sections in the design of a seamless railway line. Background technique [0002] The arrangement of unit rail sections of seamless railway lines is one of the main contents of seamless line design. The design process has a large repetitive workload and many factors need to be considered: the length of unit rail sections and the calculation of mileage need to consider internal and external work breaks. Chain and rail welded joints should avoid the transition sections of different track structures and the transition sections of different offline foundations. The buffer zone and expansion zone of the seamless line should avoid level crossings. The mileage of joints should be continuous, and the length of factory welded rails and unit rail sections should comply with relevant regulations, etc. In the past, des...

Problems solved by technology

In the past, designers had to manually design, review, and count engineering quantities, which was inefficient and prone to errors. Especially for long lines, if there was an error in the calculation of the length of a certain unit rail section, subsequent unit rail sections would need to be re-arranged, causing serious rework.

In the existing research results of the unit rail section layout of the seamless line, there are the following three problems: the design of the welded joints of the rail cannot automatically avoid the transition sections of different track structures and the transition sections of different offline foundations; the interaction of unit rail sections Cannot automatically re-arrange subsequent unit rail sections during formula editing; cannot automatically check and prompt unit rail section design results

Using the existing research results to design the seamless line unit rail section requires a lot of manual editing, which seriously restricts the work efficiency and the quality of the results is not easy to guarantee
