旋转运行状态下的叶片动应力多点位遥测系统的研究

Research on Many-point-location Remote Measuring System of Vane under State of Circumrotating and Running

针对大型风机、汽轮机等高速旋转机械的叶片由于动应力发生变化而引起变形或断裂事故 ,介绍了叶片动应力多点位遥测系统 ,重点阐述了采用 CDMA码分多址通信技术解决实时监测时的遥测通信问题及采用定子重力自平衡微型发电机解决监测系统自供电技术难题。

In allusion to the distorting or rupturing accident in tail-wagging mechanical lamina, just like large-scale wind machine, steamer and etc., it emphases the way of use CDMA code and communicating technique of marking-many-site to solve the remote-measuring and communicating problem of real time inspection and measurement, and the way of use stator gravity self-balance and miniature-generator solve the difficult problem of technique of self power supply of inspecting and measuring system.
