The invention relates to the field of wind power generator sets, and particularly provides a semiautomatic design method and device for a wind power generator set tower frame. The method comprises thesteps that at least two flange outer diameter combinations are determined according to the top flange diameter and the bottom flange diameter of the tower frame, each flange outer diameter combination comprises the top flange diameter, the bottom flange diameter, the top flange diameter of any tower frame section of the tower frame and the bottom flange diameter of the tower frame section; all the flange outer diameter combinations are screened through an optimization algorithm, and the target flange outer diameter combination is obtained; in the tower frame corresponding to the target flangeouter diameter combination, the safety coefficient of each tower frame unit meets the preset safety condition, and the mass of the tower frame corresponding to the target flange outer diameter combination is the smallest. The wall thickness of the tower frame units is optimized through the optimization algorithm, the weight of the wind power generator set tower frame is minimal, and accordingly the cost of the wind power generator set tower frame is reduced.
Description
technical field [0001] The present invention relates to the field of wind power generators, in particular to a semi-automatic design method and device for a tower of a wind power generator. Background technique [0002] The tower is the main load-bearing part of the wind turbine, and its importance becomes more and more obvious as the capacity of the wind turbine increases. The overall manufacturing cost of the tower accounts for a large proportion of the total cost of the wind turbine, and the weight of the tower is related to the supporting structure of the entire wind turbine, and it is one of the indicators for the production of the tower of the wind turbine. This shows the importance of the tower in the design and manufacture of wind turbines. [0003] Since the main function of the tower is to support the mechanical parts of the wind turbine, the power generation system, etc., and to bear the force of the wind wheel and the force of the wind on the tower, the design o...
