A simulation model is used to calculate the rocking motion of a vehicle and how antiderailing guard rails work to prevent derailment when subject to large ground excitation and the results are verified through full scale testing. (1) The simple ve...
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...
