SIMULATION TECHNOLOGY AND HOLE PARAMETERS OPTIMIZATIONOF PERFORATED SQUARE CFRP TUBES
摘要
Abstract
This paper aims to optimize the mechanical properties of perforated square CFRP tubes by finite element analysis.The failure mode,which cannot be observed in the experiment exactly,is analyzed by microscopic process.Mixed mesh for perforated tube,which considered as the best partitioning method,got a better computational efficiency and computational accuracy compared to free mesh and radial mesh.A response surface model of two objective functions and hole parameter was built and it is found that the radius of hole has the largest effect on the two responses.Finally,an optimum solution was obtained by multi-objective optimization,where the three design variables,the radius of the hole,height of the hole and the translation of the hole in cross range,are 8.98 mm,0.80 and 0.43,respectively.And the improvement of 69.5％ in SEA and a few sacrifices of 3.6％ in peak load are achieved.The simulation model and optimization method in this paper are of guiding significance for designing CFRP perforated structured.关键词
