Design and Verification of Large-Diameter Tower Sharding Platform for Wind Turbine
[Objective] In recent years, the wind turbine diameter of wind turbine has become larger and larger, which makes the wind load borne by the tower barrel more and more. In order to match the wind turbine, it is necessary to increase the diameter of the tower to meet its bearing capacity. With the inc...

| description | [Objective] In recent years, the wind turbine diameter of wind turbine has become larger and larger, which makes the wind load borne by the tower barrel more and more. In order to match the wind turbine, it is necessary to increase the diameter of the tower to meet its bearing capacity. With the increase of the diameter of the tower barrel, the diameter of the platform inside the tower barrel will also increase, and the weight will increase correspondingly, resulting in an increase in cost. At the same time, the diameter of the platform in the tower barrel increases, if the traditional platform beam is used, the welding part of the platform beam with the barrel is easy to cause a large stress concentration, and the structural failure is easy to occur, resulting in heavy losses. [Method] In order to avoid the problems of cost increase and easy failure of the welding part between the platform beam and the cylinder, caused by the increase of the platform diameter, the whole large inner platform of the tower cylinder was divided into 6 independent small platforms, and 2～3 supports were designed at the lower part of the platform, with one end of the support welded with the cylinder and one end free. The deformation and strength of the platform under two load conditions (SLS and ULS) were evaluated by the finite element analysis software. [Result] It is found that the platform is safe under the corresponding load conditions and is widely used in the field. [Conclusion] The design of sharding platform can not only meet the requirements of field use intensity, but also reduce weight and cost, and produce certain economic benefits, which has further promotion value. |
