The purpose of the present study is to develop a three-dimensional efficient interactive model and a numerical procedure to simulate a tire on soft ground, which can be applied to multibody dynamics for off-road vehicles. For motion analysis of th...
Three-dimensional motion analysis is necessary to describe the complex tire behavior on soft ground due to the deformation of the tire and the landform of the soft ground such as the ground heaving in the vicinity of the tire side edge. We develop...

The purpose of the present study was to develop and propose an analytical model with a multibody system and a numerical procedure for the safety analyses and assessments of railway vehicles during an earthquake. Recent reports show that railway 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...
