The Reserch On The Multidisciplinary Design Optimization Of The Bag Filter Based On CAE

Multidisciplinary Design Optimization (MDO) is a method for optimization of complex engineering problems. Now,it is mainly used in complex product design optimization of aerospace industry,and rapid developing. Currently, Multidisciplinary Design Optimization (MDO) has become a new direction for complex product design.In this paper, I research MDO's system and methods, on this basis,introduct it to industrial dust-removal equipment design,achieve MDO of bag filter, effectively improve the comprehensive performance of bag filter.Specifically completed the following work:First, on the basis of the domestic and international scholars researching on MDO's theory of technical methods,engineering application status and system, I discuss the MDO's definition,composition and substance, Meanwhile, analyze and contrast MDO's algorithm, process, characteristic.Second, I analyze the mathematical nature of collaborative optimization and create mathematical model of collaborative optimization. On the process of achieving CEA-based collaborative optimization framework, I introduce response surface approximation, establish collaborative optimization algorithm based on response surface and depth study by an example.Third, for bag filter such a complex structure, in combination with engineering design requirements, I determine the computational domain, propose calculation condition and underlying assumptions, establish collaborative optimization algorithm based on response surface for bag filter. I execute linear weighting for bag filter multi-objective and establish comprehensive performance evaluation function.Fourth, I achieve the multi-disciplinary design optimization computational framework under the CAE environment, successfully integrate Gambit, Fluent and ANSYS such as CEA software and establish parallel operating environment for collaborative optimization special computing framework. Making use of design optimization framework, I design and optimize the bag filter, achieve good results, provide a new design for design of complex industrial products.
