Abutment

Introduction, at Politecnico di Torino. The book describes the following research topics: (1) development of an algorithm of the contact model which can be used for real-time simulation; (2) simulation and co-simulation of the multibody models of the test rig with the proposed contact model and control system; a

Review of Wheel-Rail Contact Models,and rail is definitely the most important question for the study of the dynamic behaviour of a railway vehicle. In fact, the wheel-rail contact forces provide several fundamental functions for the vehicle: the support action for the vehicle load, the guidance action during the change of direction an

Roller Rigs,ains the main concept of the use of a roller rig as a dynamic track simulator and briefly describes the existing full scale and reduced scale test facilities. The different similitude approaches to be used when dealing with scaled prototypes and their relative benefits and limitations are also descr

平淡而無味

Design of Scaled Roller Rigs,from 1998, several studies have been performed to develop and build a roller rig able to perform tests on scaled railway bogies and single wheelsets under different operating conditions. The studies have analysed the existing scaled roller rigs, and this information has been used to design the new e

Contact Model,r rig test facility. Both wheel-rail and wheel-roller contacts are described. A bi-dimensional contact for the solid wheelset has been considered, and only the tangent track behaviour has been analysed.

Real-Time Simulation of the Contact Model,e 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
