Optimization of Macro-Geometric Parameters of Multi-Megawatt Wind Turbine
In initial design of Multi-Megawatt wind turbine,A optimized method of gears on macro-parameters is developed to in-crease power density and reduce meshing vibration.In this optimization model,chose power density and meshing stiffness as objec-tive,chose the main influence factor,then establish Multi-target optimization model,think carefully the relationship about total contact ratio and meshing stiffness and gear strength,acquire efficient optimization method.Through the results comparison of gears with high speed in 5MW wind turbine,the optimization method in this paper can effectively increase meshing stiffness and reduce transmission error,improve dynamic performance,and meet the strength requirement.compared with the results of the exper-iment,it can reduce the noise about 4％.
