Laboratory Investigation of Roller Bearing Damage Due to Impact

This report presents the results of a two phase testing program to measure the strains in the roller separators (cages) of a bearing during impact loading. The impact loading is similar to the impacts encountered during in-service operations with flat spots on the wheels. The first phase of the...

Equipment Testing and Analysis - Glazing Impact Test: An Evaluation of Two Plastic and Glass Window Systems Subjected to Projectile Impacts

Impact tests were conducted at the Transportation Test Center on two glazing systems installed in railroad locomotives, passenger cars, and cabooses. A 1/4" thick extruded polycarbonate plastic and a 1/4" thick cast acrylic plastic, each installed in combinations with a 1/4" thick sheet of tempered...

A Study of Trackside Lubricator Greases on FAST

[From the Introduction] The FAST program has used lubrication during specific periods to extend rail life in various metallurgy tests conducted since 1976. During this time, the gage-face wear rate of standard carbon rail has been used as a "baseline" for measuring comparative life of alternative...

Wheel Failure Mechanisms of Railroad Cars: Volume II - Technical Task Summaries

This report summaries an extensive research program into the causes of wheel thermal failure. Results of material property tests, review of failure data, dynamometer tests, roll dynamics unit, track tests, and theoretical and experimental stress analysis show that heat-treated wheels of designs...

Wheel Failure Mechanisms of Railroad Cars: Appendices
