Calculation method of load distribution of male mold system based on large wind power blades

The invention provides a load distribution calculation method of a male mould system based on a large wind power generation blade. On the basis that the male mould system is divided into three parts of a supporting steel frame, a section line cutting steel plate and a male mould surface glass bulb, the male mould surface glass bulb is divided into three layers of structures, namely, a glass bulb generation wood layer, a glass bulb glass steel layer and a glass bulb square steel layer. First, the supporting steel frame and the section line cutting steel plate are respectively conducted with load distribution solution seeking, and the three layers of structures of the male mould glass bulb are respectively conducted with load distribution calculation. Processing is conducted in the process of calculation through the methods that the male mould glass bulb is divided along the length direction of the blade in an equal interval mode, and then each small piece is conducted with discrete solution seeking and superposition calculation. The calculated discrete loads of the three layers of structures are conducted with superposition again. Curve fitting of discrete points is conducted through software matlab, and finally the load distribution function of the male mould system surface glass bulb and the distribution curve are obtained. The load distribution calculation method of the male mould system based on the large wind power generation blade has the advantages of being simple in calculation and high in precision.
