Abstract

The invention discloses a blade design and manufacturing method of a Mobius strip plastic blade wind-driven generator. The method comprises the following steps: a. designing a Mobius strip blade, andsetting the size, band width and band thickness of the Mobius strip blade by determining the local wind speed and wind strength; b. carrying out simulation and optimization on the performance of the Mobius strip blade, and detecting the performance of the designed Mobius strip blade by means of modeling of 3D software and by using performance analysis software. The method has the beneficial effects that the traditional fan blade is changed into a Mobius strip by means of the rectification of a wind-driven generator blade, and the Mobius strip conforms to topological transformation, so that theMobius strip is not affected in any way when being used for collecting wind power even during rotating due to being blown by the wind; the Mobius strip can be completely manufactured by means of injection molding; furthermore, the problem that the service life of the Mobius strip is influenced in a long-term weathering due to the self properties can be reduced by polishing and filling a vacancy.

Description

technical field [0001] The invention relates to the technical field of manufacturing methods of blades of wind power generators, in particular to a design and manufacturing method of blades of Mobius strip plastic blades of wind power generators. Background technique [0002] The design of blades in wind turbines directly affects the conversion efficiency of wind energy and its annual power generation, which is an important part of wind energy utilization. A Möbius strip is a two-dimensional compact manifold (i.e., a bounded surface) that can be embedded in a three-dimensional or higher-dimensional manifold. At present, there are mainly two types of wind power generation equipment, one is the horizontal axis wind power generator, which has the advantages of high efficiency and low cost. At present, horizontal-axis wind turbines mainly adopt straight aircraft propeller blades, which are mainly rigid as a whole, especially large-scale horizontal-axis wind turbines. However, ...
