Users Manual for Program TRC_PLASCUR

Table of Contents

Introduction

Program TRC_PLASCUR adds or removes designed track geometry to a Plasser&Theurer or Matisa registration. The input data file is read in free format, but the columns in the file shall have the same contents as in a mauz-file. The output data file is written in mauz-format.

Input data commands

Input data is read in free format, valid separators between the input values are <space>, <comma>, <tab>, <equal sign> or <carriage return>. The commands can be written both in lower and upper case letters. The operation of the program is controlled by the commands described below; some of the commands also need arguments.

IDENT1, IDENT2, IDENT3

Define up to 3 ident lines.

Declared= Character*80    Default= Blank

RIKTN

'A' If the A-end of the Mauzin vehicle is leading.
'B' If the B-end of the Mauzin vehicle is leading.

Declared= Character*1    Default= 'A'

A

Vector describing the distances between the different axles in the measuring vehicle. The vertical versine is measured by the axles #1, #2 and #3. The twist is measured by the axles #4 and #5. The cant is shown by axle #6. The gauge is measured by axle #7. Axle #8 is unused. The lateral versine is measured by the axles #9, #10 and #11.

Declared= Real*4(11)    Default= 11*0. [m]

INFIL

Input measuring trolley registration
The file is read in free format. The columns in the file shall have the same contents as in a mauz-file.

Declared= Character*132    Default= Blank

UTFIL

File containing the output data, written in *.mauz-format.

Declared= Character*132    Default= Blank

B

Semi-distance between the nominal running circle in a wheelset.

Declared= Real*4    Default= 0.750

TWIDTH

Nominal gauge in the track read from file INFIL.

Declared= Real*4    Default= 1.435

IPRINT

Print of the Mauzin registration to standard output.
IPRINT=0 Suppress the printout.
IPRINT=1 Print the measuring car registration.

Declared= Integer*4    Default= 0

AAD

Scale factor for lateral irregularities read from file INFIL.

Declared= Real*4    Default= 1.

AAZ

Scale factor for vertical irregularities read from file INFIL.

Declared= Real*4    Default= 1.

AARF

Scale factor for cant irregularities read from file INFIL.

Declared= Real*4    Default= 1.

AASPV

Scale factor for gauge irregularities read from file INFIL.

Declared= Real*4    Default= 1.

XSTART

Longitudinal coordinate from where the addition or subtraction will start.

Declared= Real*4    Default= 0.

LM

Length of track section to be considered.

Declared= Real*4    Default= Entire INFIL

STEGM

Equidistant distance between two consecutive lines in the output data file UTFIL.

Declared= Real*4    Default= Same distance as in INFIL

IHV

Debug print to standard output.
IHV=0 No printing.
IHV=1 Print of lateral and vertical position of rail, left and right side.

Declared= Integer*4    Default= 0

IADD

Indicator which defines if a designed curve geometry shall be added or removed. For indicator IADD is the following values valid:

IADD= –1	Removes a designed curve geometry from the measuring car registration.
IADD= +1	Adds a designed curve geometry to the measuring car registration.

The designed curve geometry is defined in the input data commands RCURVE, HCURVE, XCURVE, TCURVE and NXCURV below.

Declared= Real*4    Default= +1

RCURVE

Designed track curvature geometry to be added or removed to the track irregularities read from file INFIL.

Declared= Real*4(20)    Default= 20*0. [m]

HCURVE

Designed track cant geometry to be added or removed to the track irregularities read from file INFIL.

Declared= Real*4(20)    Default= 20*0. [mm]

XCURVE

Breakpoints defining where transition- and circular- curves starts and ends.

Declared= Real*4(38)    Default= 38*0. [m]

NXCURV

Number of breakpoints in vector XCURVE to be considered.

Declared= Integer*4    Default= 0

TCURVE

Type of transition curves to be used for the designed track geometry:

'R'	Clothoid type of transition curve, the curvature is a linear function of chainage.
'S'	Helmert type of transition curve, the curvature has the shape of two second-degree parabolas such that the curvature and its derivative are continuous functions (The Helmert curve is in Germany also known as the Schramm curve).

Declared= Character*1(19)    Default= 19*'R'
