It is a known fact that polymers and all other materials develop hysteresis heating due to the
viscoelastic response or internal friction. The hysteresis or phase lag occurs when cyclic …

Thermoplastic elastomers (TPE's) are increasingly being used in rail service in load
damping applications. They are superior to traditional elastomers primarily in their ease of …

Understanding the internal heat generation of the railroad bearing elastomer suspension
element during operation is essential to predict its dynamic response and structural integrity …

Bearing temperature serves as an important metric used in identifying defective bearings in
the rail industry. Current defect detection systems, such as the Hot Box Detectors (HBDs) …

The main purpose of this ongoing study is to investigate the effect of heat generation within a
railroad thermoplastic elastomer suspension element on the thermal behavior of the railroad …

This paper presents a detailed study of the structural integrity of conventional and modified
railroad bearing adapters for onboard monitoring applications. Freight railcars rely heavily …

❑ The test rigs are specifically designed to closely mimic railroad service operation
conditions which a railroad bearing experiences.❑ A fully-loaded railcar (100% load) …
