Abstract

Using ANSYS and subspace iteration method to analyze natural vibration frequencies of Three-directional grid LICS,Fred Boolean type LICS,Single-diagonal LICS,Double-diagonal LICS .The figures of natural frequencies and corresponding shapes are obtained.Macro parameters include span S, rise f, valley number Kn, radial node number Nx on natural vibration frequencies are analyzed under 52 working conditions.The results show that natural vibration characteristics of There-grid LICS is the best and Fred Boolean type LICS,Single-diagonal LICS and Double-diagonal LICS' are close.It provides reference for practical engineering design.
