Abstract

This article gives an overview of the DyMoRail library.The aim of this Modelica library is the simulation of longitudinal dynamics of entire railway trains. The DyMoRail library allows an efficient simulation of complete train compositions in various combinations. The library contains different car models; buffers; couplers equipped with both friction and elastomer springs; as well as the center-buffers for multiple units. DyMoRail allows to simulate the entire motion cycle that the buffer undergoes during a collision. The robust programming of the basic models allows for arbitrary combination of buffers; couplers and destruction tubes. Different modelling techniques (SIMULINK; STELLA) have been explored. Since the modular structure of Modelica allows fast and simple exchange of rolling stock and different types of couplers and buffers; it was decided to build this library in Modelica. This simulation environment was successfully used by Schwab Verkehrstechnik AG during the development of their state-of the-art center coupler product family. Within DyMoRail2 we intend to implement further features and improve the modularity and flexibility of the library.
