Abstract

FINITE ELEMENT ANALYSIS OF SMALL VERTICAL AXIS WIND TURBINES

Dong-Yang Wu*, Jian-Fan, Xiu-Qin Chen, Jian-Yang Song and Jiang-Bo Tong

ABSTRACT

Vertical axis wind turbine is widely used in wind power generation because of its simple structure, high reliability and automatic windward. In order to study the influence of shaft material, blade material and wind speed on the wind wheel of a small vertical axis wind turbine, this paper makes a finite element analysis of the wind wheel of small vertical axis wind turbine through the orthogonal experimental method. The results show that the maximum displacement always appears in the upper part of the wind turbine blade, and the maximum stress always appears in the bottom surface of the wind wheel main shaft; when the wind speed is small, the displacement and stress of shaft material and blade material change little. Then based on the ANSYS Workbench software, the modal analysis of the wind wheel shows that the natural frequency of the wind wheel is 6.05 Hz, so the frequency added by the wind wheel should avoid 6.05 Hz to prevent resonance.
