AUTOMATIC PARAMETER IDENTIFICATION APPLIED TO A RAILROAD CAR DYNAMIC DRAFT GEAR MODEL

One of the most important components in simulating track-train dynamics is the mathematical model of the connection between two cars, the draft gear-coupler combination. In this paper an automatic parameter identification technique is presented which can be used to generate a nonlinear functional relationship of dynamic draft gear characteristics using experimental data.
