Parametric design and stability analysis of hybrid ellipsoid reticulated shell
摘要
Abstract
Hybrid ellipsoid reticulated shell can overcome the shortcomings like the increase of the traditional single ellipsoidal and spherical reticulated shell with the span of S and the number of copies of the Kn ring,the construction difficulty by the increase of rod structure vertex number,and great changes of bar type and scale, thus improving the rationality of the structure and mechanical properties of the structure.According to the characteristics of hybrid ellipsoid reticulated shell,by using APDL (Ansys Parametric Design Language)language,the paper designed of macro parameters of hybrid ellipsoid reticulated shell program.By taking Kewitte-rib ring hybrid ellipsoid reticulated shell as an example,and using ANSYS software,it analyzed its mechanical properties.The results show that under the same condition,the rib ring near the hybrid ellipsoid shell vertex displacement and stress are smaller and more evenly distributed,avoiding the single shell type vertex near the stress concentration phenomenon.Its mechanical performance is better than that of the single type,Kiewitt-ribbed ellipsoid reticulated shell.Kewitte-rib ring hybrid Ellipsoid Reticulated shell the structural stress (2.35 Kn/m2)after the maximum displacement and the most disadvantageous stress gradually increases with the increase of span.The most unfavorable stress (S1 span more than 1 1 0 m,Kn =6, Kn =8 )exceeds the allowable stress,and the engineering advice span limit is 90~1 00 m.关键词
