Knorr-Bremse Rail Systems Budapest Design Challenge 2020

Knorr-Bremse announces a Design Challenge for engineering students and practicing engineers

At Knorr-Bremse Budapest, we constantly search for solutions that support environmentally friendly railway transportation. This goal can be basically achieved by mass reduction and efficient structure utilization. The special brackets applied on trains for mounting purposes pose a special challenge due to the trade-off between strength and stiffness on one hand and weight on the other.

The Challenge

Participants are invited to optimize a bracket. The goal of the optimization task is to minimize the weight of the part with mechanical strength and manufacturing requirements fulfilled. The submitted tender must include the optimized geometry and related documentation as detailed in the specification.


Ones can take part in the present challenge by filling in the registration form on this site. Participants must accept the legal notices regarding to the rules of the challenge and to data protection.

The detailed specification of the challenge is going to be sent to each participant via email after the acceptance of their registration.

Deadline: 31.08.2020

The optimized geometry and the verification documentation (requirements detailed in the specification) must be sent to

The maximal attachment size is 15 MB.

Criteria for evaluation

  • Mass reduction ratio (mass of new design / mass of original design)
  • Maximal von Mises stresses in the evaluated load cases
  • Manufacturability
  • Overall design assessment of jury

The Awards

The top 5 lightest designs fulfilling the requirements will receive rewards as follows:

  • 1st Prize – gross 300 000 HUF
  • 2nd Prize – gross 250 000 HUF
  • 3rd Prize – gross 200 000 HUF
  • 4-5th Prize – gross 100 000 HUF each
