风力机叶片气弹实验教学虚拟仿真平台设计

Design of Virtual Simulation Platform for Wind Turbine Blade Aeroelastic Experiment Teaching

利用LabVIEW共享变量技术和CDS模块,搭建风力机叶片气弹实验教学平台。利用该平台可进行叶片气弹系统的颤振风速实验、结构刚度/阻尼实验和历史实验数据分析,不仅解决了目前缺乏风力机叶片气弹实验教学手段的问题,还大大降低了使用风洞场地和实验仪器的成本,对于风电技术的虚拟实验教学改革和网络化教学,具有非常重要的意义和价值。

In this paper,using Lab VIEW shared variable technology and CDs module,a wind turbine blade aeroelastic experiment teaching platform is built.This platform can be used for flutter wind speed experiment,structural stiffness/damping coefficient experiments and historical data analysis experiment of blade aeroelastic system.It can not only solve the problem of the lack of teaching tools of wind turbine blade aeroelastic experiment at present,but also greatly reduce the cost of using wind tunnel site and experimental instruments.It has important meaning and value for the virtual experiment teaching reform and network teaching of wind power technology.
