Load
Rail Track Analysis Model Wizard
Temperature Load
Element temperatures for deck and rail are defined.
Advanced Temp. : The user can select the material composing each deck and input the temperature.
Acceleration / Braking / Centrifugal / Vertical Loads
Sectional Acceleration / Braking / Centrifugal / Vertical Loads are defined.
With respect to the left end of the whole model, the range and load for sections are defined.
| Case 1 : One track | Case 2 : Two tracks |
|---|---|
Running Direction : Train loads are applied based on the direction of the train traffic. Keep Right and Keep Left are the choices of traffic direction.
Train Section : When train vertical load is not defined, Longitudinal Resistance Data / Transverse Resistance Data of Loaded Condition in Boundary tab is applied in the region specified in Train Section field.
Load Type : One of the Acceleration load and Braking load is applied for the case of one track. Acceleration and Braking loads are individually applied for the case of two tracks. Vertical train load can be defined with the different loading value by regions.
When selecting Centrifugal as the Load Type, enter the Vertical Load Intensity only. Centrifugal forces are auto-calculated using the track radius and train speed.
Moving Load Data
Number of Track Loading Locations : This represents the number of location that the train load is applied. N number of location will generate N number of model files.
For example, if you enter 3, a model with three train loads loaded including the basic train load loading position is created.
Location Increment for each Model : Enter the moving increment for each track. If n is entered, a file with boundary conditions applied to the section where the train load is loaded at the location moved by n is created.
Number of Track Loading Locations : 3 , Location increment of Track : 10m
This set-up will generate 3 additional model files whose the train has moved 10m, 20m and 30m, respectively.
Train Speed for each Track : Enter the train speed for each track to auto-calculate the centrifugal force.
