Development of Flexible Track Models for Railway Dynamic ...
Almeida, Tiago Miguel Candeias de
The dynamic analysis of railway vehicles involves the construction of three independent models: the vehicle model, the track model, and the wheel-rail contact model. In this work, a multibody formulation is used to describe the vehicle model. A methodology is also proposed in order to create detailed track models, which include the flexibility of the rails and of the substructure. The inclusion of flexible track models is very important to stu...
