Abstract
The computer program FRATE is a non-linear, time domain digital computer program developed under Federal Railroad Administration sponsorship for the purpose of studying freight car response dynamics. The trailer on flatcar (TOFC) simulation contained in FRATE was expanded, for the purposes of the analyses of this report, to include a compliant lading representation. The compliant lading consisted of two spring mounted masses in each trailer with vertical, lateral and roll degrees of freedom. Analyses were performed to obtain the response of the TOFC vehicle and compliant lading to several track profiles and body hunting conditions. The analysis results characterize the response of a standard TOFC configuration to typical service conditions. Undesirable response conditions are noted and recommendations are made for improvements.
