초록
The vibration of a mask degrades the color purity in CRT. In order to reduce the vibration. a damping wire is put into contact with the mask in the Flatron. We analyzed the vibration of the mask considering the damping wire using FEM. The natural frequencies and mode shapes of the mask are calculated by modal analysis. And those are compared with the measured results to confirm our finite element model. The modal analysis of the wire is also performed to investigate resonance with the mask. Finally, the transient dynamic analysis of the mask contacting with the wire is performed. The vibration of the mask is measured to confirm our analysis, and the results are in good agreement with the analysis.
