| Abstract: | The wind turbine set tower is connected by four short conical towers through the bolts.The largest loaded bolt connection is obtained by the mechanical analysis of four connected surfaces.The detailed geometric model of the bolt flange is established.By software ANSYS 12.0,the contact analysis of flange bolt is done in different working conditions.The maximum stresses of the bolt and flange are obtained and both are less than the yield strength of the material,So the bolt flange connection is safety.The lar... |
