The rapid parametric modeling method for bag filters with different structure types, the combination of global and local calculations, simplified design of beam-column connections, the simplification technology of complex tube sheets in the global calculation, and the structure optimization method under non-linear and multi-constraint conditions are presented, and the software of calculation and optimization for the bag filter structures is developed. Based on the entity level system of World Tree, the modeling framework for virtual assemble of the large-scaled bag filter is proposed, and then the software for virtual assemble is designed. The welding deformation, and the distribution and variation of stress and strain of the main structures are analyzed, and finally the control method with the anti-deformation to remove the welding deformation is proposed and experimentally demonstrated.
