ABSTRACT:
The development of the tilting train can contribute to
solve the economic burden and enhance the transportation means of areas that
did not share the benefits of the high speed railway. But the dynamic behavior
caused by the interaction between the train and the track as well as the
environmental vibrations along the railway should be evaluated to secure the
safety of the train and riding comfort. In this paper a study on the
characteristics for ground vibration due to the tilting train travelling in the
conventional line are carried out. The transmitted load into the ground is
computed through a study on the interrelation between the tilting car and the
line. This load is applied into the numerical model which is one for the
analysis of ground vibration due to the travelling tilting car. The far fields
on the numerical model are formed by the absorbing boundary using dashpot, one
of the most widely used absorbing boundary in finite element analysis. Using this
numerical model, the analysis of the ground vibration characteristics caused by
travelling tilting car is performed. From the analysis, it is shown that the
transferred load due to the tilting train is larger than that of the conventional
train.
