Study on Torque Converter with Adjustable Guide Vanes of Hydrodynamic Speed-Adjusting Wind Turbines

Abstract:

As the core component of hydrodynamic variable speed transmission system of wind turbine, there exist some problems in domestic adjustable torque converter, such as simple products and poor performances. A three-dimensional flow simulation method is employed to design the adjustable torque converter. Circulatory circle is determined after the structure optimization of the torque converter. The blades are designed by the conformal projection law, and then the adjustable device’s structure is determined. The performance of torque converter with the variation guide vanes is analyzed by using numerical simulation. The calculated results show that the new torque converter could meet the needs of the wind turbine transmission system.
