Introduction

A BoBo-vehicle passes a right-handed turnout:

The rail profiles has been measured at 30 different sections through the turnout.

Download the example

Download the tar-file turnout.tgz
List the contents of the tar-file with "tar tvfkz turnout.tgz"
Extract the contents of the tar-file with "tar xvfkz turnout.tgz"

Create all kpfr files under directory kpf

Go to directory kpf
Run file optif/kpfr1.optif assuming that all profile combinations leads to one-point contact conditions
Check the generated kpfr-files by looking at all created plots in directory diags.

(Multiple files can be opened simultaneously by using wildcards. Open the PostScript files for the nine first sections with command: op diags/kpfr_00?.pdf)
Run file optif/kpfr2.optif in order to care of the switching blade by reruning sections 004 to 009.
Run file optif/kpfr3.optif in order to let cp2 continue during the closure panel by reruning sections 010 to 017.
Run file optif/kpfr4.optif in order to care of the crossing nose by reruning sections 018 to 021.

Start the time-domain simulation

Double-click file runf/turnout_R760_15.tsimf and press Ctrl+R

Animate the results in postprocessor GPLOT

Double-click file runf/turnout_R760_15.tsimf in the file text area.
Press the Gplot–pushbutton.
Open file gp/turnout_R760_15.gp by selecting File->read_GPdat in the pulldown menu bar
In the pulldown menu bar press View->show_4_diag in order to show a close up view of the wheel/rail contact
Start the animation by pressing the Fwd–pushbutton.

Modeling of a varying rail profile

How to create a varying rail profile:

First read in all kpfr-files from all cross-sections:

 insert file kpf/kpfr/kpfr_001.kpfr
 insert file kpf/kpfr/kpfr_002.kpfr
 insert file kpf/kpfr/kpfr_003.kpfr
 . . .   . .  . . . . . .

Give names to all cross-sections:

 in_substruct kpfr_001 [ no_1 ]
 in_substruct kpfr_002 [ no_2 ]
 in_substruct kpfr_003 [ no_3 ]
 . . . . .    . . . .    . .

Insert the named cross-sections along the track

 func kpf_variable_1 " "  -1000,   no_1,
                           0,      no_1,
                           0.805,  no_2, 
                           1.742,  no_3, 
                           3.142,  no_4, 
                           . . .   . .

Insert the shapes of the rail cross-sections for animation in program GPLOT
