Dynamic response of a vehicle with flexible car body moving on a ballasted track
MATEC Web of Conferences, 2018 In this study, the dynamic response of a vehicle with flexible car body moving on a ballasted track is investigated. The vehicle/track interaction model is divided into two sub-systems, namely the vehicle and the ballasted track sub-system.

Multibody dynamics: Modeling component flexibility with fixed, free, loaded, constraint, and residual modes [PDF]
The assumed-modes method in multibody dynamics allows the elastic deformation of each component in the system to be approximated by a sum of products of spatial and temporal functions commonly known as modes and modal coordinates respectively. The choice
