Study On The Frame Of Distributed Paralleled Optimization Based On CORBA

Distributed paralleled optimization is the best layout to shorten the design cycles and to enhance the utilization ratio of the existing resources during the process of modern structure optimization.In this dissertation, we combined the knowledge of paralleled algorithm, networks, FEM, structural optimization algorithm and others correlative fields, improved and realized a distributed paralleled optimization system with separate module based on CORBA. Relative knowledges on system are dealt with GA (Genetic Algorithm), Distributed computation, Finite Element Method, Structural optimization and other knowledges.According to the research and analysis of current method of structural optimization and paralleled computation, we improved and realized the paralleled optimization system based on CORBA. The work in this dissertation is done as follows:1. Introduced the current status of structural optimization and paralleled computation, and then presents the necessity of designing a distributed paralleled optimization system.2. The realized principle of the system layout is explained, including character of object oriented, parallelization of the computation process and networks connection each other and so on. Those related conceptions such as CORBA, approximation, pool of computer nodes and message oriented are dealt. It is basis and foundation of system realization.3. Based on the technology and theory mentioned in the 2, we realized the design of distributed paralleled optimization system based on CORBA. And then the system is tested with three practical engineering structural-optimization examples, as well as the feasibility and efficiency of the system are proved.
