摘要
依据德国劳氏船级社2010年发布的"风力发电机组传动系统动力学认证分析标准"(即GL 2010标准),以多体动力学仿真软件SIMPACK为仿真平台建立某型风力发电机组传动链多柔体动力学仿真模型,通过频域分析得到传动链的固有频率及能量分布图,并绘制二维坎贝尔图确定潜在共振点,通过时域仿真分析对潜在共振点进行验证,最终确定危险共振点,该文为风力发电机组传动链动力学建模与仿真提供了一种新方法,为传动链的稳定性和可靠性设计及动力学优化设计提供了理论参考。
The dynamic characteristics of drive train are very important to reliability and safety of large-scale wind turbine. The drive train flexible multibody dynamic simulation model of a certain type of wind turbine was established by the muhibody dynamics simulation software SIMPACK based on the guideline for the certification of wind turbines which published by Germanischer Lioyd in 2010. The natural frequencies and the energy distribution diagram of the drive train were obtained by frequency domain analysis, two-dimensional Campbell diagram was drew to determine potential resonance point. The dangerous resonance point was ultimately validated based on the potential resonance point in the time domain simulation analysis. A new method of modeling and simulation for the drive train of wind turbine was provided, also the theoretical reference for stability design, reliability design and dynamics optimization design of the drive train were provided.
