摘要
研究转静件碰摩状态下叶片载荷测试方法,测试叶片在碰摩力的冲击与摩擦力作用下的振动特性,给出叶片和机匣受冲击力的时间载荷和频谱,证明叶片在各种碰摩力作用下不发生共振,只受弯矩作用等现象.为旋转机械转静件碰摩作用下叶片的强度分析提供依据.
The blade load test method on the condition of rotor and stator rubbing was studied, the vibration characteristics of blade under rub impact forces and friction forces were tested, and the time load and frequency spectrum of blade and casing under wallop were presented. This proves that, under different rub impact forces, the blade doesn＇t generate sympathetic vibration, and is only subject to bending moment. All these provide a basis for intensity analysis of rotating machine on the condition of rotor and stator rubbing.
