Transit car demonstration test program on the roll dynamics unit. Volume 1. State-of-the-art-car (SOAC) creep forces and dynamic response on the roll dynamics unit. Final report

Technical Report ·
OSTI ID:5449330
This report documents two separate studies aimed at verifying and demonstrating the capabilities of the Roll Dynamics Unit (RDU), which is part of the Rail Dynamics Laboratory located at the Transportation Test Center (TTC) in Pueblo, Colorado. During testing, the RDU's potential for simulating actual track conditions was explored and results were correlated with measurements taken during in-track testing. Other efforts focused on the RDU's use as a laboratoy instrument by which selected performance parameters can be varied, and the responses of a single rail vehicle measured, under controlled conditions. Testing involved use of the Number One State-of-the-Art Car (SOAC), one of two such vehicles developed under UMTA's Urban Rail Vehicle and Systems Program (URRVS). The 90,000-pound intra-city, rapid transit vehicle, configured as an 'A' Car capable of independent or two-car operation, was tested on the TTC's Transit Test Track to provide in-track data. It was then installed on the RDU for the testing described. Information on SOAC technical/historical development and URRVS program highlights are presented as background for the discussion of the results.
