This paper deals with the motion of a submerged tethered system subject to large deformations and displacements. A tethered system usually employs a cable or wire rope to tether an attached piece of equipment to the ground or to a vehicle, e.g., a...
To minimize the risk of fatalities in the event of earthquakes, it is extremely important to prevent the derailed vehicle from deviating from the track as well as to prevent the vehicle from derailment. Authors have developed a post derailment sto...
Barrel polishing is an extremely efficient processing method for surface smoothing treatment of a large number of workpieces. However, workpieces and grinding materials may separate depending on the processing conditions. Therefore, examination of...

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...

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...
