Generation of loads from a train moving along a track
When both the train load (load pattern) and track (Traffic lane) has been defined, it is possible to generate the load cases corresponding to individual positions of the moving train.
The procedure to generate load cases for moving train
-
Open service Load.
-
Expand branch Traffic loads.
-
Select the required load pattern, track and other parameters.
-
Confirm with [OK].
-
The corresponding load cases are generated. You may review them in the Load case manager.
Train load generator
Load pattern |
Selects the load pattern that will move along the track.
|
Track assignment |
Selects the track that will be followed by the specified load pattern.
|
Load group |
Defines the load group for the generated load cases.
|
Load case name |
Specifies the base of the name of the generated load cases.
|
Step |
The selected load pattern will move along the specified track with the here-defined step. A separate load case is generated for each position of the moving load. |
Validity |
The three-dot button at this item opens a small dialogue where the user can define the validity of the generated load. In the dialogue the user inputs intervals with different "validity". Each interval is defined by its end-position and a factor. The input load is multiplied by this factor to obtain the final value of the load. The factor is a real number from interval 0 to 1. The value of 1 means that the load acts in its full size. The value of zero means that no load acts over the corresponding interval. |
