Technical Advises offered- Abroad Technical Advisor to Daimler Chrysler, Sindelfingen, Germany, for their development work on Brake Friction Materials - Since April 2007 Currently advising a giant Friction material Industry with the complete design and development work for a Plant in Shanghai/Melbourne and Kwala Lumpur since Jan 2004 - currently retained as Technical Advisor on retainership basis for 2 years. Advicing a company in South Africa in the discpad area as a Technical Advisor and have been currently retained for two years. Advicing 2 companies in Poland for Brake lining applications
for Auto and rail brake friction material design.
Product development for Heavy commercial / Passenger car
brake friction lining / disc Pads / Railblocks for the Indian/Overseas
Markets (both OE and after market segments) Fixed up agencies / changing for Technology upgradation. Negotiating techno commercial tie ups with foreign JV partners for technology transfer projects. As leader of the Technology and environment committee, spearheaded
strategic initiatives on product development and TQM implementation. Higher friction/low wear/lowest cost Medium friction/low wear/lowest
cost GMR_EP_Stopping_Distance_graph Scientific contributions Auto/Rail brake friction composite - Global/Indian Technical/Management consultancy services offered - at present
Services offered for Friction material Industry Complete Management Consultancy -with a study of the system and can formulate effective solutions for 1. Manufacturing issues which includes process /manufacturing
tools/fixtures/operational /development issue can a suitable cost effective
system with IS/QS standards in force for implementation.
4. Lean and flat manufacturing practices with TQM in place for effective implementation 5. Overall corporate and company initiatives to have a good healthy evolution of longlasting manufacturing system with the latest technology in force. Services offered - Automobile/Rail brake friction designs World Class product development - To service OE requirements of manufacturing/testing and approval process as per TQM procedures /IS/QS standards of design and testing Formulation /Process development - Exiting/New Design experiments for friction material design / standardization/validation
procedures Discpads for lowest wear(high speed high temperature wear)
at higher friction levels of course with other virtous of friction materials
1. Passenger car Brake linings -Non asbestos/ Asbestos based - HCV/MCV/LCV Normal issues addressed - Please refer the charts S1-S5 Brake effectiveness 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 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
Techniques I am conversant with include- for Rail 1. Wet and hot moulding 2. Dry and cold moulding under high pressure only 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 '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. |
