摘　　要：提出一种复现风力机五自由度载荷的主动静压加载控制方案。将风轮等效成加载盘,并沿该盘的轴向和径向均布若干静压油腔,通过液阻网络主动控制各油腔的静压力来合成并复现载荷波形。给出加载系统的设计方案和十二自由度载荷的加载策略。在此基础上,分析静压加载控制原理并进行仿真实验研究。研究结果表明,采用主动静压加载能复现给定载荷波形,加载单元具有较高的响应速度和载荷复现精度。This paper presents an active static pressure control method to reproduce5degrees of freedom loads for wind turbine.Several static pressure cavities are distributed evenly along the axial and radial directions of a loading disc which is equivalent to the wind rotor.Static pressure of such cavities can be controlled to simulate the desirable loads by controlling a hydraulic resistance network.This paper presents how this loading system can be designed and loads can be exerted to every cavity,An active control scheme is then detailed.Simulation results demonstrated that this method can be used to reproduce the wind turbine loads with fast response and trajectory tracking accuracy.
