| Abstract: | Based on such theories as wavelet analysis, applied mathematics and data structure, the tree-structured geometrical model and algorithm for the elimination-reduction of air-column-inherent frequency were proposed in order to avoid resonance between the air-column-inherent frequency of the multi-degree-of-freedom piping system and the mechanical-inherent frequency. By applying the software system based on this algorithm to the fluctuation analysis of a piping system, it was found that its calculation coincide with the experimental results very well. Therefore, it has both theoretic and practical value to the designing of a new piping system and the rebuilding of an old one in petroleum, chemical and electric power industries. |
