|Title:||A Multibody System Approach To The Wedge Damper Friction Formulation|
De Araujo H.B.
Dos Santos Jr. A.A.
|Abstract:||Secondary suspension of railway three-piece-trucks hasn't changed much in the past century. Despite this, its most common damping element, the friction wedge, is not yet fully understood. The frictional damping is a known source of nonlinearity and non-smoothness that imposes chaotic behaviors to the system, making the mathematical modeling of such devices a difficult task. The present paper presents a multibody model of a three-piece-truck's secondary suspension and the results of its simulations with three types of commonly used friction models.
