Using the 'dynamic train
crossing' function, the dynamic stress can be analyzed with ease
for any beam and shell structure with predefined trains, such as
the ICE, Thalys, etc. or user-defined trains.
|
Tracks
The description of the tracks is carried out by entering any
continuous line on the structure. Multiple track can be
considered simultaneously, so that, for example, the effect
trains traveling in opposite directions have on each other can
be investigated. |

Train Definition
The load model of the typical trains for high-speed lines are
stored in the program. Additionally, user-defined train loads
can be added. Further default parameters are the speed and the
departure time for each train. Every train is assigned to one
track. By varying the departure times, the intervals between the
different trains can be defined. |

Calculation
The dynamic train crossing can be analyzed as part of a
direct or modal time-step integration. The amount and duration
of the time steps can be entered by the user. The vibration
behavior and the desired route of the train are taken into
consideration. |
Results
Results are calculated for the deformations, speeds, and
accelerations, as well as the internal forces for every time
step. These can be represented individually or as time-step
diagrams. Additionally, the deformation can be dynamically
animated in the System Viewer. Exclusive combinations of the
results are available for further analysis. |
