Abstract

The embodiment of the invention discloses an analog simulation experiment method for a wind power variable paddle speed reducer. The wind power variable paddle speed reducer is installed on an experiment table capable of rotating around a horizontal axis; the wind power variable paddle speed reducer and the experiment table are installed with a detecting device. The method comprises the following steps of: receiving starting parameters input by a user through a control mechanism to start an experiment device; obtaining experiment data collected by a detecting apparatus when the working states of the wind power variable paddle speed reducer and the experiment table are stable. The method provided by the invention improves analog of the working state of the wind power variable paddle speed reducer and the precision of the experiment. The embodiment of the invention further provides an analog simulation experiment device for the wind power variable paddle speed reducer.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and more specifically, to a simulation experiment method and device for a wind power variable pitch reducer. Background technique [0002] The wind power variable pitch reducer is installed in the hub of the wind turbine and is used to control the gear reducer of the fan blades to rotate at a certain angle. When the reducer is working, while its transmission parts rotate to transmit power, the entire reducer will continuously rotate 360 ​​degrees with the fan hub, and its rotation axis is perpendicular to the rotation axis of its internal transmission parts. Therefore, the The mode of work of speed reducer just ceaselessly changes between down standing, recumbent and handstand. At the same time, since the gearbox adopts a multi-stage floating planet carrier transmission mechanism, the working state of its internal transmission parts is constantly changing when the reducer is workin...
