[Abstract]:With the development of computer and the development of fluid mechanics theory, the application of CFD technology to solve the engineering problem of bag dust collector is getting more and more extensive, and the requirement of individual customization is increasing day by day. In order to quickly complete the customized products, visual display, and the performance of certain estimates to achieve product improvement and optimization. In this paper, a comprehensive test and verification platform for the digital prototype of a bag dust collector is proposed, which integrates fast reconstruction, numerical simulation, evaluation, improvement, optimization and innovation. By adopting digital prototype technology, reconfigurable modular design method and integrated design analysis method, Triz innovation tool is introduced. On the one hand, through the application of the innovative software tools of TRIZ, the problems of low cost and reducing the development cycle are solved to meet the needs of individual customization, and the theoretical basis and support for the research and development of bag dust collector are provided. On the other hand, digital prototyping and rapid reconfiguration design technology are used to realize product reconfiguration and performance analysis and evaluation. In this paper, the analysis and application of the related technology and the realization method of the structure prototype and the functional prototype are carried out systematically, and the parameter transfer between the two prototypes is studied and applied. A comprehensive test and verification platform for digital prototype of bag dust collector is constructed. The main research and work accomplished are as follows: (1) analyzing and summarizing the key Pro/E function technology used to construct reconfigurable products, and giving the construction process of the digital structure prototype of reconfigurable bag dust collector based on Pro/E. The construction of the digital structure prototype of the reconfigurable bag dust collector is completed, and the data transfer between the structure prototype and the functional prototype is realized by extracting and transferring the parameters of the control flow field in the structure prototype. Through Gambit and Fluent's journal language to realize the establishment of functional prototype library and realize the full parameterization of performance simulation, a software platform for bag dust collector enterprise is developed, which can realize rapid product reconfiguration and innovative research and development. Parameterized automatic modeling and CFD analysis, result post-processing and analysis and evaluation are used to make use of Triz, aiming at the problem of bag breaking, innovating the way of air inlet, the structure of air dividing, the shape of section of box, and so on, and obtains many kinds of reconstructed types, and carries out CFD calculation and evaluation.
