Abstract :
The way in which the forces are transmitted in the rolling contact between wheels and rails of rolling stocks is complex and highly nonlinear, and understanding of braking mechanism has a crucial role for the safety and efficiency of railroad vehicle operations. This paper proposes a real-time simulation unit, that is, a HILS system, which is able to analyze braking performance of railroad vehicles. It presents a dynamic model of a railroad vehicle including bogies, brake system, carbody and wheelsets, and a creep force relationship, and presents also the system configuration including an anti-skid control unit (ASCU) and dSPACE board. The validity of the proposed real-time simulation model is verified through simulation study for the tilting train, Hanvit-200 (TTX).
