EUROBRAKE 2020: Severin Huemer-Kals - Startup and Bifurcation Behavior of Non-Linear Stick-Slip Vibrations: Creep Groan Occurrence for Increasing and Decreasing Speeds



September 2020

EuroBrake 2020

Startup and Bifurcation Behaviour of Non-Linear Stick-Slip Vibrations: Creep Groan Occurrence for Increasing and Decreasing Speeds is now available from Severin Huemer-Kals, Technische Universität Graz, on the EuroBrake website. He answers a few related questions in this Spotlight.

What do you find most interesting about the topic you are presenting on?
Main outcome of our study on creep groan vibrations is the importance of considering its non-linear behavior during testing. If you want the check for creep groan at a time-invariant operational point, you need to consider more than just holding pressure and speed constantly at the desired values: It really depends on how you get to this point.

How has coronavirus affected your work and has it had a direct impact on the work you are presenting?
In our case, COVID 19 did not have a direct impact on the research itself. However, we are now not able to receive the valuable feedback from the EuroBrake community. Therefore, I am already looking forward to a “physical” EuroBrake in 2021.

Who do you think will be most interested in seeing your presentation and who would you most like to ask questions about it?
Any expert in non-linear, friction-induced vibrations is invited to discuss the presented results with me and my colleagues!
