Abstract:

TECHNOLOGY INTERNATIONAL INCORPORATED (TII) IS PROPOSING THE CONSTRUCTION OF A DETECTABLE DEFECT DRIFT DIFFUSION (D4) MODEL FOR PREDICTION OF HELICOPTER GEARBOX LIFE EXPECTANCY. THE MODELING STRATEGY IS BASED ON PREDICTING FATIGUE OF TYPICAL MECHANICAL EQUIPMENT WITH ROLLING CONTACT, SUCH AS ROLLING ELEMENT BEARING AND GEAR OF THE HELICOPTER GEARBOX. THE RATE OF GROWTH OF SPECIFIC SIZES AND TYPES OF DEFECTS UNDER VARIOUS LOADING CONDITIONS WILL BE CONSIDERED BASED ON EXPERIMENTAL DETERMINATION OF STRESS/STRAIN TIME HISTORIES FOR COMPONENT LIFE ESTIMATION. THUS, A REALISTIC MODEL FOR ANALYTICAL PREDICTION OF LIFE EXPECTANCY WILL BE DEVELOPED BY EMPLOYING STRUCTURAL FINITE ELEMENT ANALYSIS IN DYNAMIC SIMULATION AND STATISTICAL ESTIMATION OF FATIGUE PROPAGATION. FOR THIS PROPOSAL, THE EFFORT IS RESTRICED TO THE MOST LIKELY DEFECTS ON A SINGLE REPRESENTATIVE ROLLING ELEMENT BEARING AND A SINGLE REPRESENTATIVE GEAR.
