About Me

Creative and proactive technological designer with specialization in machine tribology. Interested in modeling and simulation of mechanisms and tribological contacts, and strongly attracted to tribological testing, tribometers, and hands-on work in general. More than three years of experience designing and developing tailored testing methods and friction measurement instruments, particularly for rolling-sliding interfaces. Skilled in prototype development, testing, and failure diagnosis of electromechanical systems.

My design project concerns the design and development of a testing method and a test set-up for accelerated testing of cam-roller follower interfaces. 

During my design project I have focused my research on the following topics:

  • Cam-Roller Follower Contacts. 
  • Tribological Testing.
  • Tribological Testing Setups.
  • Mixed EHL Lubrication of Rolling-Sliding Contacts.
  • Friction in Rolling Sliding Contacts.
  • Calculation of Stribeck Curves.
  • Frictional Moment in Roller Bearings.
  • Flexure Mechanisms.
  • Motion Control.
  • Modeling and Simulation of Tribological Contacts.

With the knowledge acquired, I came up with a novel testing method and test setup concept for tribological testing of cam-roller follower interfaces. These concepts have been validated throughout modeling and simulation of tribological contacts and a proof-of-concept prototype.
