DYNAMIC HOPPER CAR TEST
This report describes a test designed to establish the relationship between ride performance and track degradation, vehicle component wear, and the combined effect of rail degradation and component wear. The test was also designed to quantify the dynamic response of freight vehicles to different track structures. Two 100-ton hopper cars, one a high-mileage car and the other a low-mileage car, were instrumented and used to measure lateral and vertical wheel/rail forces, and truck and carbody modal accelerations. The results of the test will be used to quantify the dynamic response of freight vehicles to different track structures and to establish a baseline for future study of ride performance, and track and vehicle degradation.
