The Research Of Computer Cooperate Optimal Design For Process Equipment Based On CAE Technology

Both the clamp connections of horizontal push vulcanizing boiler and the tooth-locked quick closure device of tooth-locked quick closure pressure vessel are the important non-standard components of process equipment.Because of Complex structures, the quality of a horizontal push vulcanizing boiler and a tooth-locked quick closure pressure vessel is the highly nonlinear multivariable complex function about process parameters material mechanical parameters and structural sizes which results in structural design so far is still a black box experience trial and error design process for process equipment. How to establish the scientific method is the technical problems need to be solved for engineering design.The theoretical premise of solving the engineering problems is to study the establishment of non-conventional automation intelligent optimizating design theory of process equipment. However, rare domestic related research has reported which makes researchs on Intelligent automated optimizating theoretical for process equipment have important theoretical research value and engineering value. Based on Intelligent optimizating theory, the theory and technology of computer collaborative integrated intelligent optimizating design automation is established for non-conventiona process equipment in this paper which lays the science theoretical foundation for China's breakthrough technology and theory of process equipment design. and the main results are as follows:The procedures of three dimensional structural automatic design is wrote by measns of PROE parametric language and the automation design of three-dimensional structure of process equipment is realized. the procedures of finite element automatic stress analysis are compiled by ANSYS APDL language for process equipment, the stress analysis automation and automated extraction of stress results are achieved.Based on three dimensional design software PROE, finite element analysis software ANSYS and multidisciplinary optimization software ESIGHT, the theory and method of computer collaborative integrated intelligent optimizating design automation is established for non-conventiona process equipment, the technological platform of computer collaborative integrated intelligent optimizating design automation is created for non-conventiona process equipment, the technical problems of the software data communication and design process automation were solved, the process equipment intelligent optimization design theory and method is also established based on the multi-island genetic algorithm.The stress and mass intelligent optimization analysis of horizontal push vulcanizing boiler and the DN 1200 tooth-locked quick closure pressure vessel are implemented based on above research results.Unde rthe satisfaction of strength conditions, the maximum stress of clamp connections reduce more than 25% and its mass can also reduce more than 50% after optimization,and the maximum stress of tooth-locked quick closure flange can reduce above 10% and its mass can also reduce above 10% after optimization. The better economic benefit is achived...
