Tour of two new machines created at Center for Railway Research IIT Kharagpur

The "Rail-Wheel Contact Simulator" at Center for Railway Research (CRR), IIT Kharagpur can be used for following:
(1) Test "Friction Modifiers (FM's)" to be applied on railway wheels/railway track to reduce wear, contact noise, and energy consumption
(2) Recreate conditions at railway wheel-track contact (pressure, shear stress, sliding speed, environment, etc.) in laboratory. This can be used to troubleshoot problems related to wheel-rail wear and rolling contact fatigue
(3) Determine traction-slip characteristics under different operating conditions (pressure, sliding speeds, environment, etc.) that help determine braking distance, conditions for wheel locking, and maximum traction that can be obtained
The "Rail-Wheel Contact Simulator" has six hydraulic actuators that can used under closed loop motion or load control. Very precise location control (to less than 50 microns) is being achieved on the machine. Normal load, lateral load, roll angle, roll centre, yaw angle, yaw centre, can be independently varied. Peak contact pressures of up to 1500 MPa can be achieved.
The "Reconfigurable Mechanical Loading Setup" can be used to do uni-/bi-axial testing of large suspension elements such as air-springs, conical rubber springs, coil springs, etc. in monotonic or cyclic loading conditions. Vertical, lateral, torsional and bending rigidities of springs/structures/joints can be tested on these machines.

Proud of you, Prof. Racherla! And, I am especially delighted to share with everyone that it is you who has been teaching the course of Design of Machine Elements to our undergraduate students.

[@jusjaisinghani8179]

Exactly Sir! Its inspirational to see professor's teachings in application directly!

[@baiduryabhattacharya9987]

Vikranth - the complete professor of engineering!

[@mkgaming990]

Wow awesome congratulations professor sir ji jai hind
Till now I had seen these things in textbook only in DKOM and DOM subject

[@vikranthracherla]

Thank you

[@bbmandal]

Congratulations for what you have done !!! And best wishes for all future endeavors ...proud of you. Dr. B B Mandal (Mining Engg. IIT Kharagpur)

[@vikranthracherla]

Thank you Prof. Mandal

Congratulations whole team

[@prateekmishra913]

Congratulations Professor and to the entire support team, for the remarkable feat in self sustainability for analysis of rail wheel interaction in real terms. Wishing you and the team for many more achievements!

[@kraj2217]

Congratulations sir! Appreciate you taking these efforts to advance railway research. All the best :)

[@visakhkrishna4050]

Really inspiring Prof.Racherla. All the best!

[@koraksarkar]

This is such an amazing achievement Prof. Racherla. Congratulations to the whole team.

[@ashishkumarnath]

Congratulations.

Thank you sir

[@shaileshdpatel3514]

It is very remarkable job has been done. Congrats team !

[@jusjaisinghani8179]

The scale is just remarkable! Congrats sir!

[@vikranthracherla]

Thank you Jus

[@ujjawalarya4837]

Congratulations Prof. Racherla and your team. It's a really comendable job!

[@brocklesnar8818]

Result of years hard work

[@saddy704]

Remarkable achievement 🙏👌👌

[@leletejas]

Congratulations

[@PawanKumar-ee8tw]

Sadly, only few will understand the technical aspects of it. Now railways will
be filled by marginally qualified students appearing in CSE, earlier it was top priority of Engineering Students.
Thanks to the idiots who met in “Parivartan Sangosthi” held on 07th & 08th December, 2019 at New Delhi.

[@sandeepkarmakar4286]

SIR I WANT TO TALK WITH YOU..HOW CAN I TALK SIR?? PLEASE REPLY ME SIR ITS SO ESSENTIAL🙏🙏🙏

Good work for railways but said for Engineers.
Stupid policymakers mainly Burocracrats, who are self declared genius in every field introduced #IRMS with dumbest argument that railways gazetted (group A) officers only require managerial skills and technical knowledge is of less importance.
