| 摘 要： | 风力发电机组在自然条件下运行时,作用在叶片上的空气动力载荷、重力载荷、惯性载荷等交变载荷将使叶片和塔架产生耦合振动。为了得到其在额定工况下各阶模态振型,判断系统运行的稳定性,以沈阳工业大学SUT-1000风力发电机组为例,对其进行动力学分析。将叶片和塔架进行离散化处理,在叶片上模拟施加气动载荷,应用MSC ADAMS进行仿真分析,得到了系统的各阶模态。分析结果对风力发电机组的总体优化设计提供了理论依据。

| Abstract: | When the wind turbine works in natural conditions,the aerodynamic load,gravity load and inertia load acting on the blade of wind turbine can result in coupling vibration of the blade and tower.In order to get the vibration modes and judge the running stability of the unit,dynamic analysis was performed using MSC ADAMS software.Taking the wind turbine SUT-1000 of Shenyang University of Technology as an example,the blade and tower were discretized,the aerodynamic load was defined on the blade and then the vib... |
