| Abstract: | Roller's surface crack is an injury phenomenon which often appears when the roller is working,so it is necessary to detect crack damage.A finite element model of roller with surface crack was established to calculate the roller's natural frequency and mode,and the influence of the position and depth of surface crack on the roller's natural frequency was analyzed,providing the basis for the identification of roller's crack damage by vibration characteristics. |
