| 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 ... |
