| Abstract: | Stability of fiber winding composites circular lattice structure was analyzed using finite element method.Optimal design program of circular lattice structure was compiled using APDL(ANSYS Parametric Design Language) of ANSYS.Under two kinds of constraint status,free end and radial fixed end,changing law of load-to-mass ratio which is attached to winding angle,aspect ratio,number of loop stiffener and couples of helical stiffener has been researched utilizing the optimal design program.As a result of theore... |
