基于遺傳算法的橋式起重機結(jié)構(gòu)進化設(shè)計
[Abstract]:With the development of biological evolution theory, evolutionary technology has become a general problem solving technology, which is more and more popular. By learning the process of evolution and solving the complex problems in life, the theory of biological evolution is perfectly applied to practice. Among all evolutionary algorithms, genetic algorithm is the fastest developing and the most popular one. The genetic algorithm uses the method of studying target population to extract genes, organize searching for multiple regions of solution space, carry on genetic operation and variation, analyze fitness, produce better offspring, inherit many times, and then produce ideal optimal solution. It has the characteristics of self-organization, self-learning, self-adaptation and so on. It is especially suitable for large-scale parallel computing. Moreover, it has high evolutionary efficiency, simple operation and strong generality. The finite element theory has been widely used in engineering practice, which not only improves the precision of structural analysis, saves the time of structural design, improves the efficiency of design, but also realizes programmed and parameterized design. The combination of evolutionary design theory and structural finite element analysis can be applied to the metal structure design of overhead crane, which has remarkable scientific research and economic value, and can better guide the engineering practice. Firstly, the paper deeply studies the literature about genetic algorithm and structural evolutionary design at home and abroad, summarizes the research history and development status of structural evolutionary design, the important role and engineering application of finite element theory in the design of large-scale metal structures. Then using the finite element analysis software ANSYS APDL language to carry on the parametric modeling to the overhead crane, and according to the crane design criterion to carry on the working condition analysis, on this basis, combined with the genetic algorithm to establish the mathematical model, The genetic evolution operation, fitness analysis and multi-generation evolution of genes with parameterized metal structure were carried out. Finally, the optimal solution was obtained, that is, the optimal structural size, which meets the requirements and uses the optimal material. Finally, the algorithm of the paper is encapsulated by VC 6.0.It forms a simple user interface and is easy to use in engineering. Based on the practical design of metal structure of overhead crane, combining the advantages of genetic algorithm and finite element analysis of structure, this paper not only realizes the fast calculation of metal structure under various working conditions, but also combines the advantages of genetic algorithm and finite element analysis of structure. Finally, the fast parallel optimization of structural design gene in multi-direction is completed, and finally the satisfactory optimal solution is obtained, which can guide the engineering practice better.
