전산해석을 통한 마찰교반용접용 스핀들의 에어베어링 강성 예측 연구

다국어 초록 (Multilingual Abstract)

Recently, as global concerns regarding the environment have surged, changes in material-joining technologies have transpired. Friction stir welding, which is much more environmentally friendly than the existing welding methods, is attracting attention as a new alternative. This paper presents a method for predicting the stiffness using computational analysis when designing a spindle for frictional stir welding by applying air bearings rather than conventional ball bearings. Through fluid analysis, the pressure exerted on the spindle by the air entering through the inlet is calculated. and calculate the 0.005 ㎜. Additionally, the pressure in an eccentric state is calculated. The pressure is converted to stiffness using a formula, the corresponding stiffness is applied to the spindle, and the radial load generated during friction is input at the end of the spindle. Finally, a structural analysis is conducted to determine whether the stiffness is sufficient to determine the feasibility of the design.
