The procedure of the adaptation, described below, includes the following steps: (1) integration of the contact model, which can be used for real-time simulation, in Simulink; (2) co-simulation of the multibody model of the test rig with the proposed contact model and control system (this step is required to generate input data needed for further verification of the real-time contact model); (3) real-time simulation with the dSpace hardware system.

Due to the coach weight reduction, the car body structure becomes more susceptible to structural vibrations that affect the passenger comfort. In modern vehicles, seats are important elements to achieve the desired comfort, but in order to design and estimate the actual comfort level, the whole system must be considered, including the track excitations, a vehicle detailed dynamic model, and the coach and the seat flexibility. This paper describes a numerical model of a double-deck vehicle developed using a MB code that considers measured track irregularities, a detailed vehicle model, and a transfer function of the seat obtained by experimental tests on an optimized seat. In order to make the numerical model more reali...
