Abstract

The present invention discloses a classification and calculation method and apparatus for standard suspension pipe components of a nuclear power plant process pipeline. The method comprises: determining the basic attribute and the load performance of the to-be-classified and calculated standard suspension pipe components, classifying the to-be-classified and calculated standard suspension pipe components, and obtaining a simplified model; determining whether the to-be-classified and calculated standard suspension pipe component contains a plane curved rod; and if the plane curved rod is contained, selecting to check a dangerous cross-section, and according to the difference of the R / h ratio of the dangerous cross-section, selecting different formulas to calculate the force and the torque of the dangerous cross-section, and finally carrying out strength check. According to the technical scheme of the present invention, for the shortcoming of the long check cycle in strength calculation by using the existing bracket finite element method, manual check on the bracket strength of the standard suspension pipe components in batch is realized, fast check effects can be exerted on modifying the key section size, the similar type or corresponding pipe clip structure design can be further carried out, and the allowable load can be determined, so that the unnecessary repetitive finite element modeling calculation process is avoided, work efficiency is improved and the construction application time is reduced.

Description

technical field [0001] The invention relates to the field of pipe standard support and hanger pipe parts, in particular to a classification calculation method and device for standard support and hanger pipe parts of nuclear power plant process pipes. Background technique [0002] Pipe support and hanger is an important part of the nuclear power engineering piping system and an important guarantee for the safe operation of the nuclear power plant piping system. Whether the layout of pipe supports and hangers is reasonable, whether the structure selection is appropriate, and whether the quality is reliable directly affects the stress state of pipes under different working conditions, and then affects the safe operation and service life of nuclear power plants. At the same time, due to the huge number of pipe supports and hangers, whether to use standardized support and hanger products has an important impact on the construction progress and cost of the project. [0003] At pr...
