Name: Qiang Liu

Company: Tribology Research Institute Southwest Jiaotong University

Presentation Title: The Effects of Structural Stiffness in Vibration Transmission Paths on Friction-Induced Vibration (EB2021-FBR-004)

Session: Materials, Manufacturing and Design (rail), Wednesday 19th May 2021, 09:00 - 10:40 (Central European Summer Time - CEST)

What do you find most interesting about the topic of your presentation?

I tried to use transmissibility function to analysis the relationship between the structural stiffness of vibration transfer path and the frictional self-excited vibration, which is the most interesting about the topic.

When discussing this topic with industry peers, what question are you most frequently asked? How do you answer it?

Others usually want to understand how I define the vibration transfer path, which is answered in my paper.

Who do you think will be most interested in your presentation, and who would you most like to ask questions about it?

I think engineers who are concerned with braking systems may be interested in my presentation.

What specific topics or technology are you hoping to see in other presentations or in the exhibition?

I hope to see some interesting conclusions about the relationship between micro-surface topography and frictional self-excited vibration.
