to solve the problem of difficulty and low efficiency in modeling of the overall tower, this paper puts forward finite element modeling method based on tower modular. Putting 2Z2E3 type tower as a carrier, the modularization theory as guidance, using large finite element software ANSYS, this tower was modular analyzed, such as division, establishment and assembly of module and the modal analysis of tower after assembly. As a result, the vibration period accords with the procedures requirement, which shows the feasibility of the tower modular modeling method, provides the basis and reference for further modular and parameterized modeling of tower.
