Users Manual for Program TRC_MAUZCUR

Table of Contents

Introduction

Program TRC_MAUZCUR adds or removes designed track geometry to a Mauzin-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. A(1) - A(8) defines the distances between the axles measuring the vertical irregularities. A(9), A(10) and A(11) defines the distances between the axles measuring the lateral irregularities. When the A-end of the vehicle is leading axle #5 measures vertical track irregularities. When the B-end of the vehicle is leading axle #4 measures vertical track irregularities. Lateral irregularities are measured by axle #10. The twist is measured by the axles #4 and #6 if the A-end of the vehicle is leading. The twist is measured by the axles #5 and #3 if the B-end of the vehicle is leading. When defining the axle distances it is recommended to use axle #10 as reference axle i.e. A(10) = 0. Axle #10 is used for measuring the gauge of the track.

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

INFIL

Input Mauzin-registration file
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 Mauzin 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 Mauzin registration.
IADD=+1	Adds a designed curve geometry to the Mauzin 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'
