Abstract

The vibration happened at the revolution movement of driving shaft driven with the thrust of airplane affects the great influence on the life of the shaft. And a great loss of life is caused when the fatigue damage is occurred at the driving shaft during revolution. The chattering is occurred at the driving shaft placed at the various revolution due to the aviation environment. Therefore, the part of the driving shaft concerned about the fatigue damage is grasped through the analysis study in this paper. So, the durability to prevent damage can be improved and it is possible to be grafted onto the convergence technique on the basis of a recent safe design and show the esthetic sense.

항공기의 추력으로 구동되는 추진축의 회전운동에서 발생되는 진동은 추진축의 수명에 큰 영향을 끼친다. 그리고 회전중 추진축에서 피로파괴가 발생하게 될 시에, 막대한 인명피해를 야기하게 된다. 비행환경에 따라 다양한 회전에 놓이게 되는 추진축에서 떨림이 발생한다. 따라서 이러한 피로파괴가 우려되는 추진축 부위를 본 논문에서는 해석적 연구를 통해 사전에 파악함으로서, 파손방지를 위한 그 내구성이 향상되고 근간된 안전설계를 토대로 융합기술에 접목하여 그 미적인 감각을 나타낼 수 있다.
