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.
