At Mid Niigata Earthquake in October 2004, a Japanese high speed train was derailed under commercial operation at the speed of 200 km/h. Investigations of the case concluded that the horizontal ground motion by the earthquake was the major cause o...

Recent reports imply that railway vehicles could be derailed solely by the ground motions of earthquakes without fatal damages of vehicles or tracks. Based on the reports and facts, we believe that we should further study the derailment mechanism ...
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...
