Abstract

The invention discloses a fatigue life evaluation and prediction device and method based on a wind turbine generator. The device comprises a test box; the lower inner wall of the test box is fixedly connected with a plurality of miniature wind turbine generators; detectors are fixedly connected to the to-be-detected assemblies of the miniature wind turbine generator; a connecting cover plate is arranged at the top end of the test box; a plurality of connecting blocks are fixedly connected to the bottom end of the connecting cover plate; the plurality of connecting blocks are arranged on the outer side of the bulge of the connecting cover plate; the top end of the test box is also provided with connecting grooves correspondingly matched with the connecting blocks. According to the invention, the equal proportion models made of the same material are adopted for real simulation, simulation of ventilation, illumination, rain wash and the like is carried out on the miniature wind turbine generator set, accordingly, corresponding data are obtained, and the service life of the wind turbine generator set can be accurately deduced according to the data.

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a device and method for evaluating and predicting fatigue life based on wind turbines. Background technique [0002] In recent years, the global utilization of renewable energy has been increasing year by year. In renewable energy, wind power is a very important part. The fatigue life of the wind turbine is determined by the shortest fatigue life of its key components. [0003] Due to the very long service life of the separated generator set in reality, it is usually only possible to use computer simulation to estimate its service life, resulting in large errors. Contents of the invention [0004] In order to solve the shortcomings existing in the prior art, the purpose of the present invention is to provide a fatigue life assessment and prediction device and method based on wind turbines, which uses a proportional model of the same material for realistic simulation, ther...
