Simulation Studies of a Ventilated Brake Disc With Variable Friction Plate Thickness

Name: Gai Fulin

Presentation Title: Simulation Studies of a Ventilated Brake Disc With Variable Friction Plate Thickness (EB2020-FBR-015)

Session: Posters, Monday 17 May 2021, 17:30 - 19:30 (Central European Summer Time - CEST)

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

We found that the variable plate thickness has very little effect on the disc’s dynamic DTV and brake torque variation, but incurs an obvious lateral run-out and coning in the form of first order waviness, which are likely the cause behind the hot judder issues observed in the road tests.

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

Q: Is this kind of complained disc observed in the after-market very often?

A: It is rarely observed if we follow the normal process.

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

The vehicle companies may be most interested in our study which provides them another thought on brake judder.

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

The following topics we are interested in:

1) the main causes and mechanisms of brake judder.

2) how to effectively evaluate brake judder in-house?

3) is there any FEA method to evaluate brake judder?

Register for EuroBrake 17-21 May 2021 to see over 100 technical presentations and posters, access technical content and replay sessions for three months after the event, and network with the community in the online event platform.
