Because of the complex structure, the quality of the vulcanization tank and the tooth-mesh quick-door pressure vessel is the process parameter The multivariable and highly nonlinear complex function of material mechanical performance parameter and structure size result in its structure design still belongs to the black box operation design process of experience trial up to now. How to establish its scientific design method is a technical problem to be solved urgently in engineering, and the theoretical premise of solving this engineering technical problem is to study and establish the intelligent optimization design theory of unconventional process equipment.

Based on the theory of intelligent optimization, this paper studies and establishes the theory and technology of computer cooperative integration intelligent optimization automation design of unconventional process equipment, which lays a scientific theoretical foundation for the breakthrough of process equipment design technology and theory in China. The main achievements are as follows: using the parameterized language of PROE, the 3D structure design program of process equipment automation is written, and the automation of process equipment 3D structure design is realized. Using ANSYS's APDL parameterized design language, an automatic program for finite element stress analysis of process equipment is developed, which realizes the automation of stress analysis and parameterized extraction of stress results. Based on 3D design software PROE, finite element analysis software ANSYS and multidisciplinary optimization software iSIGHT, the method and theory of computer collaborative integrated automation design for process equipment design, finite element analysis and intelligent structure optimization are established. On the basis of this, an intelligent optimization platform for computer collaborative integration of process equipment is established, which solves the technical problems of data communication between software and automation of design process. The theory and method of process equipment intelligent optimization design based on multi-island genetic algorithm are studied. Based on the above research results, the stress and quality intelligence optimization analysis of flat push vulcanizing tank clamps and DN 1200 toothed meshed autoclaved tanks are carried out. The maximum stress of vulcanization tank clamps can be reduced by more than 25% under the condition of satisfying the strength of the optimized size series. Its quality can be reduced by more than 50%. The maximum stress of the flange can be reduced by more than 10%. Its quality can also be reduced by more than 10%, and obvious economic benefits have been obtained.
