Focusing on the problem of sound field of scattering due to the existence of tubes, the general mathematical model modeled according the condition of plant, and then the coefficient of sound scattering is resolved by using the method of inverse matrix, the functions of arbitrary configuration of tubes is got, the far field scattered pressure and near field scattered intensity of the unit of heat exchanger tubes is calculated, at last, the effect of soot cleaning due to the existence is analyzed
論文根據爐內管束的實際情況,建立換熱器管束聲波散射的通用數學模型,利用迭加原理法求解模型中的待定散射作用系數,得出任意布置管束的散射聲場特性,並具體計算鍋爐換熱器管束單元聲波散射遠場聲壓分佈和近場壁面的聲強分佈,最後分析由於聲波的多重散射作用而對聲波吹灰的影響。Main contents list as follows : 1. eai communication mechanism of vrml 2. feature based model restructure 3. mapping algorithm of model 4. assembly processing analysis 5. creating mechanism of assembly model 6. optimization of model 7. assembly constraint relations processing prototype system of web - based interactive virtual assembly platform is developed based on studies above, and its functions, such as data management of network virtual product, definition of assembly tree structure, control of assembly, etc, are implemented and have gotten well engineering application effect
