글라스 울(Glass Wool) 생산용 스피너의 토출 홀 방향에 따른 응력해석

다국어 초록 (Multilingual Abstract)

The spinner used in the production of glass wool is a key part that makes glass molten metal of 1000degrees or more in the form of thread by high-speed rotation of 2,000rpm. Accordingly, this study aims to analyze the cause of failure of the existing model through stress analysis of the spinner and to extend the life of the spinner by changing the design. As a result of the stress analysis, the existing model showed stress concentration between the holes and the cracks growing through the holes. This is similar to the actual failure pattern of existing spinners. As a result of stress analysis by using a model in which the direction of the discharge hole of the spinner was changed, it was confirmed that the model having a 10 ° tilt angle of the hole in the direction of rotation of the spinner showed a longer life and durability than the original spinner. In the model where the angle of the hole is 10° in the direction of gravity, it is confirmed that the stress is more concentrated as the thickness of the stress concentration portion becomes thinner. These results are expected to contribute not only to the durability and life span of the spinner, but also to the productivity of the product.
