Study on the Effects of System Parameters on the High Cycle Fatigue Life Based on Structural Dynamic.analysis of a Turbine Blade System

터빈 블레이드의 구조동역학해석에 근거한 시스템 인자들의 고 사이클 피로수명에 대한 영향도분석

In this paper, the effects of the system parameters on the high cycle fatigue life based on structural dynamic analysis of a turbine blade are investigated. Conventional studies have forcused on the fatigue life of turbine blades with specific system parameters. However, each parameter has statistical deviation because of inhomogeneity of material property, tolerance, and operating conditions. Therefore a methodology that estimates the effects of system parameter on the fatigue lift deviation is demonstrated.
