概要

This paper presents a model which predicts the effects of banding application to TV glass bulb under vacuum stress. Though the bend is wrapped around the periphery of the panel, the pressure is found to apply only over corner area. Automatic finite element mesh generation program BULB-3D is used, and the analysis is done by general purpose S/W ANSYS. The reuslt is verified using recovery data which are used in customer's process, and is found to agree within 3% error. As a result of banding parameter variation, it is found that there exists an optimum value of force which maximizes the stress reduction. The banding height should be as high as possible to reduce the stress.
