Problems solved by technology

The problem brought about by this is that not only there is a lot of repetitive work in the blade design process, but also the design of each blade needs to be calculated from the beginning to the end
Moreover, a lot of waste will be caused in the process

Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] The invention analyzes the aerodynamic and structural adaptability of the blades of the horizontal axis blower fan, performs modular division on the blades on the basis of the analysis, and establishes a module parameterized database. On the basis of the prototype blade, fan blades that meet customer needs are designed by replacing specific modules and modifying blade parameters in a small range. The present invention is suitable for situations where there is little difference in demands among different customers or the difference range of difference between old and new demands of the same customer is small. The flowchart of the adaptable design method of the present invention is as figure 1 shown.

[0059] (1) Establish a blade model library containing different specifications and models. Since the fan data is company and enterprise secrets, the present inven...

Abstract

The invention relates to the field of horizontal-axis wind turbines, in particular to an adaptable design method of horizontal-axis wind turbine blades. The method comprises the following steps that firstly, a model base containing blades in different types and specifications is built by means of a prototype blade; secondly, the adaptability of the structures and functions of the blades is analyzed; thirdly, modularized division of the blades is conducted; fourthly, the characterization parameters and control parameters of modules are created; fifthly, module information content computation, blade modularized optimization and module combination are conducted; sixthly, the aerodynamic characteristics and structural characteristics of a combined blade are evaluated. When the blades are upgraded, some function is added or replaced or the running wind field of a wind turbine is altered on a small scale according to the customer requirements, a specific module only needs to be replaced on the basis of the prototype blade to achieve that the blade parameters are modified on a small scale, and the customized customer requirements can be basically meet, so the design efficiency is greatly improved. The development and manufacturing cycles of the blades can be shortened, the market changes can be quickly dealt with, and the blades are convenient to reuse, upgrade and maintain.

Description

technical field [0001] The invention relates to the field of horizontal-axis wind turbines, in particular to an adaptable design method for blades of horizontal-axis wind turbines. Background technique [0002] At present, with the global emphasis on clean energy, the development of wind energy in various countries is also gradually increasing. In the design and manufacture of wind turbines, it is necessary to consider different wind fields, different customer needs, and the manpower and material resources required for design and manufacture. , financial resources and other factors have led to the diversification, large-scale and flexible development of fans. Fan blade is the most important part in the design process of wind turbines, and its design process mainly includes two parts: aerodynamic design and structural design. The main goal of the aerodynamic design of the blade is to obtain the best aerodynamic performance and improve the utilization rate of wind energy of t...
