Abstract

Aiming at the problem of poor structural stability and reliability of small and medium-sized wind turbine towers, based on a 5kw wind turbine cylindrical tower , the influence of shape parameters of lattice tower on its structural performance is explored and the corresponding lattice tower is designed. The structural performance of the cylindrical tower and lattice tower is analyzed and compared under the cut-out wind speed condition, at same time to verify the feasibility of the lattice tower. The results show that the structural performance of the lattice tower is optimal when the form of the webs is oblique, the angle of the webs is 50°, and the aspect ratio is controlled at 1/4. And the designed lattice tower meets the structural performance. Compared with the cylindrical tower, the forced distribution of the lattice tower is more evenly, the material utilization rate is better, and the stiffness is better.
