In recent years, much dynamic analysis and structural analysis have been done while considering abnormalities, such as derailment and collisions with foreign objects. In such situations, longitudinal force that exceeds design load may be applied t...

With the increasing use of the International Space Station, humans have more opportunities to work in space. In space, a mobility device that operates efficiently is needed. But, some problems must be solved. First, the human body is suspended wit...

Recently, increasing numbers of very small-sized automobiles like a personal vehicle have been developed. As the mass of such small-sized vehicles is often comparable to that of their drivers, the coupling motions between them is increasing in com...

With the increasing use of the International Space Station, humans have more opportunities to work in space. In space, a mobility device that operates efficiently is needed. In this research, a mobility system called the "Tether Space Mobility Dev...
Primary study on identifying deviations in the alignment of ground coils (ground coil irregularities) for magnetically levitated systems is conducted. The ultimate goal of this study is to introduce an active suspension system with preview in the ...
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...
