Composite brake blocks for rail road applications
Some of the Brake Block designs which i have worked with include:
Composite Rail block for Railways.- in line with BBA Becorit and BBA/Indian friction techniques.
For Rail Both in K and L block gone through the field testing and development and can develop a matured product with no issues of excessive wheel wear/excessive block wear/noise/Thermal wheel crack/smoke/or other failure mechanisms.
Techniques I am conversant with include- for Rail
K and L block development -I have developed for a company in India very successfully running in EMU units (K blocks).
L block for Wagons and Coaching besides Locomotives including GM locomotives.
Currently developing for high speed local trains in Euro rail under schedule 541-3 VE (upto 300 kms) for a company in Europe.
for K block - Bremsen mit Bremsklotzsohlen aus Verbundstofff--K Block(cleared for Euro rail )as per UIC -Kodex UIC 541-4
LL-- Braemsklottz B126/RP18/ aemsklottz
LL-- Braemsklottz sohlen Guterwagen with a block width of 250x80 +5
x2 and 320x80 +5 X2 with a wheel diameter 820 mm(the schedule demands 0.01-0.02 tolerance overall)under development.
SYNOPSIS OF DYNAMOMETER TEST RESULTS DONE FOR INDIAN RAILWAYS
'K BLOCK - NON -ASBESTOS TYPE
'K' Type Non - Asbestos composition brake blocks
Test results have shown that eighty percent of bedding was obtained in 390 and 395 brake applications at speed of 60 kmph and 1500 Kg brake force for 1st and 2nd pair of brake block.
The mean co - efficient of friction 97.2% and 88.9% values under dry condition are within UIC band for 1st and 2nd pair of brake block.
The mean co - efficient of friction 75.0% values under wet condition are within UIC band for both pair of brake block. The percentage variation in mean co - efficient of friction values under wet condition as compared to dry are +7.7% to -24.0% and +11.4% to -11.0% in the speed range of 50 to 140 Kmph for 1st and 2nd pair of brake block. The UIC specifies, co - efficient of friction values must not vary, with other condition remaining same by more than ±15%
After drag braking, at 60 Kmph with 1500 Kg brake force under warm condition, the values of mean co - efficient of friction are 0.173 and 0.207. The friction values as per UIC stipulation could not be compared as the test under cold and dry has been done at 50, 80, 120, 140 Kmph only.
The specific wear rate of the 1st and 2nd pair of brake block sample are 4.20cc/Kwh & 3.22 cc/Kwh as against the UIC specified limit of 375 °C.
No deterioration in physical condition of wheel and brake block except width wise crack on 1st pair during bedding that did not deteriorate further and on 2nd pair surface crack at the end of drag test observed.
