TESTING AND DEVELOPMENT OF HIGH SPEED RAILWAY BEARINGS
The environment for high-speed journal bearings involves a number of complex interacting factors. A dynamic simulation has been developed that allows bearings to be assessed under relevant and reproducible test conditions. It has been shown that the bearing force environment can be divided into static, quasi-static and random dynamic components. Thermal considerations are important in determining high-speed roller-bearing performance. Friction torque measurements are useful in examining bearing behavior. A relevant test must consider both thermal and dynamic loads.
