Parametric modeling and shape optimization of hybrid saddle reticulated shell
摘要
Abstract
Hybrid shell can take the advantages of each single traditional shell,which can not only increase the span but also obtain higher economic benefits at the same time. Macro program of six kinds hybrid saddle reticulated shell parametric design were developed by ANSYS parameter of design language according to saddle reticulated shell features. The mechanical performances were analyzed and the shape optimization under 108 kinds of working condition for Kiewitt-Lamella Saddle Reticulated Shell was studied with objective function of minimum steel consumption and shape optimization design variables Kn( ring to symmetric regional copies number ),Nx( radial node ring number),Ns( the upper structure of radial ring). The results showed:The maximal displacement and the most unfavorable stress of Kiewitt-Lamella were 6. 9 mm and 25. 1 Mpa,which were the least of six kinds hybrid saddle reticulated shell that its mechanical performance was the most reasonable under the same condition. The vector height f was inversely proportional to the most unfavorable stress,existing suitable f made their respective overall deflection minimum,and Ns changed the law of the unity on both;When span S=60 m and the f=30 m were certain,existing one kind of working condition of Kn=8,Nx=12 and Ns=8 under the precondition satisfied the strength,stiffness and stability,making the total steel consumption of reticulated shell lightest.关键词
