Updated: May 13, 2021

Name: Jinghan Tang

Company: Jaguar Land Rover

Presentation Title: Mode Split Brake Disc Design Optimization for Squeal and Thermal Judder (EB2020-STP-004)

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?

This project has an ambitious goal of utilising CAE tools to optimise the brake disc design. The most interesting part of this work is how to align the CAE tools and create the iterative disc optimisation process.

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

One of the most frequent question would be how does the thermal mechanical hot spotting model work. Basically, this model reproduces the thermo-elastic instability positive feedback loop in the finite element environment in time domain. But the pad was modelled in frequency domain which significantly improve the efficiency of the model.

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

I believe the brake disc suppliers would be very interested. This method would help the suppliers design more NVH robust disc within short time period with lower cost.

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

Regenerative braking changes the usage of friction brakes forever which brings new challenges to the NVH engineers. I’m interested to see the relevant research and technologies such as lifelong brakes and electromechanical braking.

About Jinghan Tang.

Dr Jinghan Tang is a dedicated brake testing and simulation researcher & engineer from Jaguar Land Rover, UK.

Jinghan’s research in brakes NVH started with the topic of FE and CFD co-simulation of brake disc in 2011. The work was then published at Eurobrake 2013. He obtained the MSc in Mechanical Engineering with Distinction at University of Bradford, UK in 2012 and then progressed to PhD in the Automotive Research Centre at Bradford. The focus of his PhD was the finite element modelling of disc brake hot spotting. During his PhD and research assistant period, he participated various research projects with Bentley Motors, Jaguar Land Rover and Airbus in the area of brake NVH testing and simulation.

In 2017, he joined Jaguar Land Rover as an NVH CAE engineer in the UK. As a simulation expert, he is leading the CAE process and tool development in the topics of brake thermal effects, wear, judder and creep groan using both finite element method and multi-body simulations. He is also appointed as an honorary visiting research fellow and guest lecturer of the Automotive Research Centre at University of Bradford.

Jinghan’s journey as an Eurobrake author started from 2013. In 2019, he received the Eurobrake best written paper award. This year’s work (EB2020-STP-004) will be his 8th Eurobrake paper/presentation.
