It is well known that enhancing safety against a large earthquake is recognized as a very important issue in Japan. So, constant effort is made to address this issue along the Tokaido Shinkansen. For example, the railway infrastructure has been re...
This paper presents the comparison of the on-line and off-line contact algorithm. Contact force between wheel and rail is one of the most influential characteristics for evaluating running stability and safety of railway vehicles. The contact poin...
Numerical simulation is one of the effective methods for evaluating safety and stability of railway vehicles. In this paper, we formulated equations of motion of the 3D-models of vehicle and track considering 3D-contact geometry, rail flexibility ...
Wear of rail is one of the phenomenon caused by wheel/rail contact. Wear of rail don't occur in shortly, however, there is a relation close to crack initiation. Additionally, it is possible to influence on the running stability or the curving perf...
Recently, increasing numbers of very small-sized vehicles like a personal mobility have been developed. As the mass of such small-sized vehicle is often comparable to that of their drivers, the coupling behavior between them is increasing in compa...
