| Imperial Competitive Algorithm is put forward by Esmaeil in2007, belongs to theemerging senior heuristic algorithm. Similar to genetic algorithm, the algorithm is derivedfrom the historical evolution of human society,it simulates the colonial power in the historyof the competition between the colonial plunder and colonial empire. After the practiceproved that Imperial Competitive Algorithm has higher optimization accuracy but due to therandom search, the algorithm may falls into local optimum,which affects the optimizationresult.Imperialist Competitive Algorithm is improved in this paper, and by using practicalexamples prove high optimization efficiency of the improved algorithm.At the same time,using the improved Imperial competition algorithm for lightweight frame structurecalculation, solving the optimization problem of a light-duty truck frame.(1) Introduce the basic theory of Imperialist Competitive Algorithm,put forward theimprovement of the Imperialist Competitive Algorithm targetiing for the defects.Thenumerical example shows the feasibility and efficiency of the improved algorithm.(2) Basing on MATLAB and ANSYS to work together, writing improved empirecompetition algorithm program and sums up the competition algorithm the basic principlesof programming.Based on MATLAB and ANSYS to work together, writing improvedempire competition algorithm program and sums up the competition algorithm the basicprinciples of programming.(3) By ueing ANSYS, analyse the truck frame structure with the finite element theoryin different working conditions, and draw the boundary conditions of truck frameoptimization; Optimize the truck frame by ANSYS zero-order algorithm,ImperialistCompetitive Algorithm,and improved Imperialist Competitive Algorithm.Find the minimumweight of the truck frame.According to the optimization result, improved ImperialistCompetitive Algorithm shows obvious advantages in structure optimizing and its practicalsignificance in engineering. |
