Animated Computer Graphics Modeling of Rolling Bearing Dynamics

Abstract

A two dimensional animated graphics model to simulate dynamic motions of the balls and cage, in a plane normal to the bearing axis, in an angular contact ball bearing is developed. The graphics modeling is based on the primitives available under the Programmers Hierarchical Interactive Graphics System (PHIGS), which is now an international standard and it is supported on a wide range of computer systems. Appropriate transformations to produce the animated motion of bearing elements are derived from the dynamic solutions provided by the bearing dynamics computer code ADORE. Necessary modifications to ADORE to store all the required solutions in an ASCII data file are performed. This newly developed data file provides the interface between ADORE and the graphics model. Since PHIGS graphics standard is very widely supported, the graphics model developed herein can be used on a wide range of computer systems. For the present investigation an IBM-RISC/6000 work station is used.
