Embodiment Construction

[0063] When drawing the structural size of any component, it is necessary to program the process software, which is the process of automatically drawing the external structure size of the component. However, for a component with a certain shape, the size of the component is constantly changing according to the design requirements. This variable size is designed as a variable parameter in the software programming process.

[0064] The present invention adopts the finite element software to illustrate by taking the main shaft of the wind power generating set as an example, the main shaft structure is as follows figure 1 As shown, after the user needs to input the specific size parameters (A, B, C, -------0, radius, aperture and number), the programmer designs the interface of the component parameter input display menu by himself. According to the designer's requirements, the values ​​of these parameters and sizes are continuously input from the interface, so as to meet the calcu...

Abstract

The invention relates to a design method of a parameterized part of a wind generating set, belonging to the technical field of wind power generation. The design method comprises the following steps: 1. designing a three-dimensional graph of a parameterized dimension of the part; 2. acquiring the stress and the displacement of the part; 3. determining fundamental dimensions of the part according to a calculating result of the step 2; 4. carrying out the design of an engineering processing and manufacturing drawing and a manufacturing process requirement according to the determined fundamental dimensions of the part, and finally completing a design report and an engineering drawing by designers. The design method can simplify the mesh modeling of the part to enable the analysis calculation of a finite element to be simple and fast; software designed by the design method can simultaneously complete the integrated design and the structural design of the wind generating set and simultaneously complete calculation, analysis, check work and drawing design.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a parametric component design method of a wind power generating set. Background technique [0002] The structural design of the wind turbine is mainly based on the requirements of the overall technology to complete the calculation, analysis and adjustment of the geometric dimensions of all parts, so as to finally determine the structural dimensions of the components; usually determine the limit load and safety factor according to the grade of the wind turbine, This process requires repeated checking and calibration, and finally finds the appropriate structural size. Usually, this process takes a long time. Designers have to go through more than 2 years of large-scale software learning and application experience. Even if they are familiar with the use of general-purpose ANSNY software, It will take more than 2 years to complete this design process. For th...
