- Abstract:
- Reliculated shell strueture is characterized by simple configuration, the internal foree distribution e-venly, easy to manufacture and assembly, and so on. Aeeording to the prineiple of network shell configura.tion ,a method for single spherical shell configuration of network design was proposed based on CAGD, throughwhich the unneeessary rounding errors brought by conventional computational modeling proeess could be elffee.tively avoided and the complete symmelry of network shell modeling was achieved. Through the research ol240 body surfaee monolayer shells modeling, we analyzed the impaet of rod length ratio with diameter and rola-tion angle of pentagon on the rod length and eventually obtained the conditions of rod length uniformly.
