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.
