VSS Demonstration Program Part 2 - Model Development and Data Analysis

The Vertical Shaker System (VSS) was the initial test program to be conducted at the Rail Dynamics Laboratory. The objectives of this program were to demonstrate the performance and capabilities of the VSS and to accumulate test data to be used in checking the validity of analytical models. The experiments were performed on three different load configurations of a trailer-on-flatcar (TOFC). The test program was found to be successful. Pretest planning, to specify input levels and motion requirements, was essential to effective VSS operation. Log books, used to record program events as they occurred, were found to be invaluable in post test analyses. Part 2 of the report includes a description of the analytical model development of the TOFC configurations, documentation of the associated time domain computer program, test data used to verify the analytical models of the TOFC configurations, and a description of the process of verification.
