The FE model for shot peening often assume that shots impact vertically on the engineering parts to generate compressive residual stresses. However, the shots obliquely impact on the surface in actual peening. In this work, we propose a 3D finite element (FE) model for evaluation of residual stress ...

경사충돌 해석모델에 반영된 재료는 무엇인가? | 경사충돌 해석모델에 반영된 재료는 숏피닝 공정이 많이 행해지는 AISI4340 소재이다. 소재를 815 °C에서 담금질 후, 230 °C에서 2시간 동안 뜨임 처리했다. | |
숏피닝 가공의 특징은? | 숏피닝 가공은, 금속재료 표면에 무수한 숏볼 들을 투사시켜 발생된 충돌에너지가 재료에 전이 되어, 압축잔류응력을 생성시킨다. 이러한 숏피닝은 부품의 내피로 및 내부식성 등을 향상시키는 기술 로서 자동차, 발전설비, 항공우주 산업에서 활발히 활용되고 있다. | |
숏피닝 가공은 어디에 활용되고 있는가? | 숏피닝 가공은, 금속재료 표면에 무수한 숏볼 들을 투사시켜 발생된 충돌에너지가 재료에 전이 되어, 압축잔류응력을 생성시킨다. 이러한 숏피닝은 부품의 내피로 및 내부식성 등을 향상시키는 기술 로서 자동차, 발전설비, 항공우주 산업에서 활발히 활용되고 있다. 이에 피닝의 압축잔류응력 평가는 내구성 및 신뢰성 평가와 관련되어 그 중요성이 꾸준히 강조되고 있는 만큼 무한한 발전 가능성을 갖는다. |
