【Abstract】 Industrial manufacturing industry is facing the market change quickly, productdiversification demand, in this context, the state environmental protection standardsbecome strict, this makes the bag filter new product research and development is of greatsignificance, but the bag filter belong to large industrial equipment, are greatly influencedby site work environment, and imperfect existing test equipment, and the relativelybackward research and development technology, so the bag filter for a new productinnovation experiment method is very urgent. This paper puts forward a new product forbag filter design of digital integrated simulation experiment method, explores the digitalprototype integration semi-physical simulation method and key technology, for largeinjection pulse bag filter product development requirements, the construction of digitalprototype and access method of semi-physical simulation are given, and finished bag filtersemi-physical simulation experiment system construction, design of experiment andsimulation test.This paper analyzes the related research results of domestic and international, in viewof the bag filter digital test prototype integration semi-physical simulation experimenttechnology and application were studied, including the main innovative workFirst of all, the digital prototype integration semi-physical simulation experimentresearch methods is proposed based on digital test prototype technology, digital prototypetechnology, and semi-physical simulation technology.Secondly, studied the composition and working mechanism, structure of bag filter,analyzed its structure design principle and key techniques of digital test prototype.On this basis, this paper realized the bag filter semi-physical simulation mathematicalmodel building and the design of the physical model, CFD numerical simulationtechnology research, and hardware connection design theory method.Finally, by injection and filtering experiments with pulse bag filter as examples,constructed the semi-physical simulation experiment system, designed the experimentscheme, realized the numerical simulation experiment, and completed the simulation test.Actual application shows that through the digital prototype integration semi-physicalsimulation experiment technology applied in bag filter, can explore new technologies for new product innovation development mode of bag filter, shorten the development cycle,reduce development costs, ensure the quality of research and development.更多还原
