Abstract
An analytical solution of axial vibration problem formulated for a composite anisogrid lattice cylindrical shell with massive disks attached to its ends is presented in the paper. The lattice cylinder is analysed using a continuum model having effective stiffness parameters equivalent to the original anisogrid structure. Axisymmetric deformations of the vibrating shell are modelled using classic theory of orthotropic shells. A formula enabling rapid and reliable calculations of the frequency of axial vibrations is derived and verified using a finite element analysis. Based on this formula, effects of the geometry of lattice structure and masses of the disks are investigated.
