Abstract

This paper studied about the dynamic characteristics of vertical axis wind-turbine type H. From the rotor dynamic viewpoint, vertical axis wind-turbine (VAWT) has weakness point compared to the horizontal axis type wind-turbine. The tower has sustained the multiple loads except the weight loading of the Wind-Turbine's blades itself. All the rotational loads were transferred directly to the tower. It follows that several problems that often occurred are natural frequencies vibration with its mode shape. The experimental investigation of the vibration, by using the static bump test and dynamic test, were performed to acquire the natural frequencies of the wind-turbine system. Furthermore, by using numerical simulation code ANSYS, the wind-turbine system was simulated to obtain dynamic response of the wind-turbine system and to identify the critical parts of the wind-turbine system. The simulations results show that the critical part of VAWT type H was shown on the tower which may cause significant dynamic deformation. The natural frequencies and the structural strength of the H type wind turbine are higher.
