The invention discloses a wind
turbine generator dynamic
response analysis method based on multi-platform co-
simulation, and belongs to the technical field of wind
turbine generators. Aiming at structural components of a wind
turbine generator, 3D
solid modeling is completed through a Creo platform, and a Creo model is imported into an ABAQUS finite element platform. According to the actual working conditions, the correct constraint relationship of each part of a finite
element model of a whole unit in the ABAQUS is set, and
simulation is conducted to obtain the intrinsic frequency and mode shape of an
impeller assembly and the whole unit.
Coupling response between the inside of the unit, that is, between an
impeller and a
tower, is discussed through response
simulation, the natural vibration characteristics of key components and the whole unit are studied by using a
finite element simulation method, the dynamic
response characteristics of the wind turbine generator are obtained by using time-varying wind pressure distribution as the main excitation load, the wind turbine generator dynamic
response analysis method based on multi-platform co-simulation has significances to improvingthe structure design of the unit and formulating effective diagnosis strategies.
