VERTICAL TRACK MODULUS: TEST RESULTS AND COMPARISON OF ANALYSIS TECHNIQUES

A vertical track response test was conducted at the AAR Track Structures Dynamic Test Facility. This test was intended to characterize the behavior of the track structure under increasing vertical loads. It was also intended to evaluate the different techniques available for the calculation of the vertical track modulus. The response of the track was obtained by monitoring track deflection under increasing vertical loads. This load and deflection data was then used to calculate vertical track modulus, track stiffness and track compliance. Three widely used techniques were used to calculate the vertical modulus.
