Abstract: Huaneng Fuxin wind tower, for example, the first model based on lumped mass and spring coefficient method
of soil-structure interaction (SSI) calculation model, the axial force generated by blade rotation, consider using dynamic
analysis tower dynamic characteristic of the blade and the tower of coupling it with the cabin, leaves reduced to focus on
the quality of an additional tower at the top, according to D. Alembrt theory tapered tube set up wind power tower
structural dynamic equations, based on consideration of soil-structure interaction wind power tower tapered tube finite
element model, based on its constraints and conditions of all the freedom to do tapered pipe wind pared and
analyzed
