Animated Computer Graphics of Rolling Bearing Dynamics

摘要

An animated graphics model has been developed to display the motion andinteractions in rolling bearings. Graphics primitives in the standard PHIGS (Programmers Hierarchical Interactive Graphics System) libraries are used to develop graphic structures of the various bearing elements and graphic objects. Components of bearing element motion, as obtained by solution to the classical differential equations of motion for all the bearing elements, are used to edit the local transformation elements in these structures and then refresh the display as a function of time. Thus an animated motion of bearing elements is produced. Graphic capabilities, such as double buffering and z-buffers are used to present a smooth animated video. The net outcome of this project is a computer code AGORE (Animated Graphics Of Rolling Elements) which interfaces with existing bearing dynamics code, ADORE, to display the bearing motions in an animated fashion.
