Numerical Method Analyze the Coupling Relation of Hydraulic Cylinder of the Variable-Pitch Wind Turbine at Low Temperature

摘要

this paper, that base on the model of Hydraulic System of the Variable-pitch Wind Turbine, focuses on the coupling relation between components of hydraulic cylinder through numerical method. Then, it will verify the results of coupling analysis according to the result of simulation by Matlab. Finally, the verification proves that this numerical method is reasonable and effective.
