Rail wear is one of the phenomena caused by rolling contact of rail and wheel. Situation of rail wear changes with complexity because the contact of rail and wheel changes gradually according to the running condition of vehicles and track geometry...

The derailment mechanism for when earthquakes occur has been verified in vibration bench tests and simulations in the past. However, in the past full-scale vibration bench tests including ours, the wheels did not rotate. The aims of this study are...

Preventing railway vehicles from derailing is the most important earthquake countermeasure. Similarly, formulating measures to prevent vehicles from deviating from the track in the event of a derailment is an extremely important secondary measure ...
In recent years, some systems which contain a floating body, such as Unmanned Aerial Vehicle (UAV) connected with a tether, are used for transportation. However, the coupling motion of the system is not easily predicted with high accuracy and may ...
This paper proposes a method to simulate the primary bending vibration in a test stand consisting of one-third segment car body and a full-scale bogie of magnetically levitated (maglev) vehicles. The purpose of this system is to evaluate an effect...

Behavior analysis of a coupled train under crash condition has several difficulties, because a coupled train has structural, mechanical and kinetic aspects. Many kinds of behavior can be observed when longitudinal heavy force is applied to a train...

A restraint on the wear of train wheels and rails of a railway is required to improve running safety and reduce maintenance cost. Wear is one of the problems that need to be settled in managing railway property. In order to deal with this problem,...

One method to evaluate the running stability of railway vehicles is a running test on roller rigs. In this study, we carried out running tests in order to investigate the differences in the dynamic behavior of half-body and full-body vehicle model...
