Abstract

A loading device simulating high power blower fan five-degree of freedom loads is provided; a loading disc is rotatably sleeved by a main shaft; a left end axial loading cylinder set is applied to the left side face of the loading disc, a right end axial loading cylinder set is applied to the right side face, and a radial loading cylinder set is applied to the outer peripheral surface; the left end axial loading cylinder set, the right end axial loading cylinder set and the radial loading cylinder set are formed by hydraulic cylinder arrays arranged on a plurality of point positions located on the left side face and the right side face of the loading disc and arranged at intervals on the outer peripheral surface in the peripheral direction; the hydraulic cylinder array on each point position comprises a loading cylinder controlled by an electro-hydraulic proportional directional valve and N-1 loading cylinder controlled by normal switch reversing valves; a computer control system can control the electro-hydraulic proportional directional valve aperture and the loading access number of the N-1 normal switch reversing valves, thus obtaining a random loading force in a formula scope on each point position. A large scale hydraulic cylinder may increase the making cost, is low in system response speed, and poor in system dynamic performance; the loading device simulating high power blower fan five-degree of freedom loads can solve said problems.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, in particular to a loading device for simulating the five-degree-of-freedom load of a high-power wind turbine. Background technique [0002] As an emerging renewable green energy, wind energy has considerable reserves and clean and renewable properties, and its development and utilization is one of the important ways to solve the energy crisis. Since wind turbines are generally installed in high mountains, wilderness and seas with harsh climates, the wind turbine drive chain needs to bear the load caused by unstable wind speed and direction for a long time, which will lead to gear box gear damage, spindle bearing failure and other failures. These problems seriously affect the life of the unit and increase the maintenance and repair costs of the fan. Therefore, it is of great significance to build a large-scale multi-degree-of-freedom load loading device that can completely simulate...
