ABSTRACT: The Vertical Shaker System (VSS) is the initial test program to be conducted at the Rail Dynamics Laboratory. The Objectives of this program are 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 are performed on three different load configurations of a trailer-on-flatcar. 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.
