Abstract

The invention belongs to the field of computers, and particularly relates to a loader layout method and device, computer equipment and a storage medium. The loader layout method comprises the steps: obtaining blade parameters of a wind power blade, and determining the distribution position range of a loader on the wind power blade and the mass range of the loader; generating a parameter matrix ofthe loader according to the position range and the mass range, wherein the parameter matrix at least comprises a position matrix and a mass matrix; and calculating modal parameters of a mode formed bythe wind power blade and the loader by taking the parameter matrix as a variable, and taking the parameters meeting a preset constraint condition as loader layout parameters. By carrying out modal analysis on the wind power blade and the loader system, the loader layout method determines the position range of the loader on the wind blade and the mass range of the loader firstly, and then furtherlimits the position of the loader on the wind blade and the mass of the loader through constraints of conditions such as bending moment, fixed frequency and exciting force, to obtain optimized loaderlayout parameters and guarantee the accuracy of test data of the wind blade.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a loader layout method, device, computer equipment and storage medium. Background technique [0002] Large-scale wind turbines will be the development trend of my country and developed countries in the world in the next few years, and the blades of large-scale wind turbines will also become more slender, and their reliability issues will gradually be concerned. One of the main reliability issues of wind turbine blades is the fatigue load of the blade, which is now tested experimentally to ensure that the blade can withstand the fatigue load during its entire service life. [0003] In the past, the fatigue test of wind turbine blades was usually based on the bending moment load along the span direction of the blade, and a single point excitation was applied to complete the fatigue test. However, the fatigue test of large blades requires more energy and higher precision. Using ...
