5.2.2.4 Data for pantograph calculation according to UIC and EBO

Pantograph flexibility index t
The pantograph flexibility index describes lateral displacement of the pantograph bow
lifted to 6.50 m when applying a force of 300 N. (Calculation of vehicle construction
gauge is based on a value of 0.03 m.)

Pantograph construction- and installation tolerance tau
The tolerance for constructing and installing the pantograph is the permitted deviation
from the vehicle body’s centre line and the middle of the pantograph bow lifted to
6.50 m. (Calculation of vehicle construction gauge is based on a value of 0.01 m.)

Adjustment tolerance vehicle suspension Theta
The adjustment tolerance of vehicle suspension is that inclination, the vehicle body may
take due to installation defects of suspension, if the vehicle stands still unloaded on a
horizontal rail. (Entry in radian! Calculation of vehicle construction gauge is based on a
value of 0.005)

Pantograph lower articulation installation height ht
Installation height of the lower pantograph articulation above Rp.

Half width of pantograph bow bw
Width of pantograph bow according to UIC 608. According to UIC 608, the following
widths ( 2 bw ) are permitted:
–
1.,45 m:
SSB, FS, SNCF (25 kV), CFL (25 kV),
–
1.60 m:
BR, SNCF (25 kV), SNCF (1,5 kV),
–
1.95 m:
CFL (3 kV-), CSD, DB, DSB, MAV, NS, ÖBB, PKP, SNCB, SNCF
(1,5 kV-), VR, (DR)
Pantograph calculation according to UIC:
You must enter the half width of pantograph bow only for evaluation in the
Y-Z graph (cross section). This value does not affect the pantograph
verification according to UIC.

Choice of nominal power supply for calculation according to UIC
When operating the powered vehicle under nominal power supply of 25 kV, a safety
distance of 170 mm from the reference profile is to be kept for uninsulated live parts.
