Abstract

The invention provides a method for determining the strength of a nacelle cover of a wind power generating set, the steps are as follows: establishing a geometric model of the nacelle cover of a wind generating set, including glass fiber reinforced plastic parts and steel parts of the nacelle; importing the geometric model of the nacelle cover of a wind generating set The finite element analysis software defines the unit properties, material properties and section properties of each part of the nacelle cover, establishes the finite element model of the wind turbine nacelle cover, and sets the wind speed and direction instrument in the finite element model; the wind turbine nacelle cover The finite element model imposes constraint boundaries; loads are applied to the finite element model of the wind turbine nacelle cover, and the strength of the wind turbine nacelle cover is calculated. In the technical solution of the present invention, the finite element model of the wind turbine nacelle cover includes glass fiber reinforced plastic parts and steel parts of the nacelle cover, and also includes an anemometer, so that the force situation of the simulated nacelle cover is more realistic, and the strength of the nacelle cover is improved. The calculation result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of strength analysis of a wind power generating set, and in particular relates to a method for determining the strength of a nacelle cover of a wind power generating set. Background technique [0002] With the rapid development of social economy, people's demand for energy is also growing rapidly. However, due to environmental factors such as carbon emissions and the increasing consumption of storage capacity, the use of fossil energy as a non-renewable energy source is limited to a certain extent, so people are actively looking for other clean and non-polluting renewable energy sources to replace traditional energy sources. of fossil energy. [0003] Clean energy such as wind energy and solar energy has been paid more and more attention by people, especially wind energy. Due to the strong support of national policies, the degree of localization of wind turbines has gradually increased in recent years. In ...
