Abstract

The invention provides an experiment table of a wind generating set. The experiment table comprises a base and a first loading device. The first loading device is fixedly arranged on the base, and the loading end of the first loading device is fixedly connected with the input end of the wind generating set to load loading torque Mx in the first direction. The experiment table further comprises a second loading device fixedly arranged on the base and a bearing seat. The experiment table further comprises a bearing seat, and a bearing is arranged in the bearing seat and sleeved on an input shaft of the wind generating set. The loading end of the second loading device is fixedly connected with the bearing seat to load loading force Fx through transfer of the bearing and the input end. The experiment table of the wind generating set loads a set to be tested by arranging size loading devices and providing loading force and loading torque in the three directions. Load of the wind generating set and received in actual work condition is truly reflected to achieve the aim of testing bearing capability of the wind generating set and improve test experiment reliability.

Description

technical field [0001] The invention relates to a detection technology of a wind power generating set, in particular to a wind power generating set test bench, which belongs to the technical field of wind power generation. Background technique [0002] The rotation of the impeller of the wind power generator drives the generator inside the nacelle to work, so that wind power generation can be realized. The impeller is subjected to 3 forces and 3 moments in three-dimensional space at high altitude, so the load on the wind turbine is very large, and the force situation is very complicated, and the values ​​of these 6 loads vary greatly under different working conditions. The impact on the nacelle components of the wind turbine and the tower supporting the nacelle cannot be ignored. [0003] In order to ensure product quality, wind turbines usually need to carry out simulated loading experiments on the test bench before leaving the factory to test the ability of wind turbines ...
