ANIMATED COMPUTER GRAPHICS MODELING OF ROLLING BEARINGS DYNAMICS

AN ANIMATED GRAPHICS MODEL TO SIMULATE DYNAMIC MOTIONS IN ROLLING BEARINGS IS PROPOSED. FOR A TYPICAL TURBINE ENGINE BALL BEARING, AND EXISTING BEARING DYNAMICS COMPUTER PROGRAM SHALL BE USED TO OBTAIN A REAL-TIME SIMULATION OF GENERAL MOTION OF THE BEARING ELEMENTS. THIS SIMULATED MOTION SHALL THEN BE USED TO COMPUTE FUNDAMENTAL COORDINATE TRANSFORMATIONS WHICH WILL BE APPLIED ON GRAPHICS SEGMENTS, WHICH CONTAIN THE SHAPE OF BEARING ELEMENTS UNDER CONSIDERATION, TO OBTAIN AN ANIMATED MOTION. IN THE PROPOSED PHASE I EFFORT, TWO-DIMENSIONAL GRAPHIC DISPLAYS IN A PLANE NORMAL TO THE BEARING AXIS SHALL BE CONSIDERED. THIS WILL PROVIDE AN ANIMATED PICTORIAL REPRESENTATION OF THE BEARING FROM A VIEW ANGLE ALONG THE BEARING AXIS. BOTH THE CAGE AND BALL MOTIONS SHALL BE CONSIDERED, AND THE FEASIBILITY OF THE OVERALL TECHNICAL APPROACH SHALL BE DEMONSTRATED BY THE ANIMATED BALL/CAGE INTERACTIONS AND THE RESULTING DYNAMIC MOTIONS. ONCE THE FEASIBILITY OF THE MODELING APPROACH IS PROVEN A MORE RIGOUROUS DEVELOPMENT OF GENERALIZED THREE-DIMENSIONAL MOTION WITH ARBITRARY VIEW ANGLES SHALL BE CONSIDERED IN PHASE II. ASIDE FROM THE GENERAL MOTION, THESE COMPLEX PICTORIAL DISPLAYS SHALL INCLUDE TEMPERATURE AND STRESS CONTOURS IN APPROPRIATE BEARING ELEMENTS AT ANY POINT IN TIME.
