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.Abstract: 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.
