The Tutorials at EuroBrake 2017 will take place from 08.00-12.00 on Friday 5th May. There is an additional charge of EUR 160 per person; to register for one of the Tutorials please select the specific session when registering online for EuroBrake. Spaces are limited for both tutorials so to avoid disappointment please book as soon as possible.
Tutorial 1. Raw Materials, Formulation and Processing
This Tutorial will focus on the following:
- Systematic approach in the study of the interaction among components, including modelling and DoEs
- Influence of raw materials on the final product characteristics, their effects on tribology and comfort as well
- Challenge coming from the “green requests”, i.e. Cu free materials and processes with low environmental impact
- Effects of process parameters and heat treatments on the final characteristics of the friction materials
- The influence of the new emerging markets on the formulation of the materials; from the global perspective to a local material customization
- How can the formulation of friction material proactively prepare solutions to the new disruptive technologies, e.g. brake by wire, energy recovery systems, in-wheel technologies?
- What is the role of material science and nanotechnologies on the characteristics of the new friction materials?
About the Tutors:
Vice President, Chief Technology Advisor & China Friction R&D, ITT Motion Technologies.
Mr Buonfico has more than 40 years in Research and Development of industrial products, mainly in the field of innovative materials and processes. He has 11 years experience in the field of special steels formulations for several automotive, railway and nuclear applications, 30 years in the friction materials formulation and processing. At ITT Motion Technologies from 1988, he was acting as quality director till 1994, then he was R&D director till 2014.
Mr. Mohammad Vakilihas been in Friction Material industries, both aftermarket and OE, since 1978. He has a B.S. & M.S. in Chemical Engineering from the University of Massachusetts and post graduate studies in the University of Bradford, U.K.
He has held numerous positions from Process & Product Developmental Engineer/Formulator to Vice President of Technical Services & International. During his tenure, he worked for Wagner Automotive, HKM, ITT, Continental and Fritec. Mr. Vakili is currently an industry consultant and has been teaching Friction Materials for nearly 15 years globally including for SAE.
Tutorial 2. Basics of Brakes and Brake NVH
This Tutorial will be divided into two parts:
Part 1 - “Fundamentals of Brake Noise & Squeal Measurement”
- Will discuss fundamental understanding such as, brakes as oscillatory systems, excitation mechanisms (forced vs. self-induced vibration), examples of unwanted brake noise and vibration, classification and root causes of various brake noise, approach and methodology, measures to avoid unwanted noise and vibration
- Discusses standard test set-ups, vehicle vs. dyno tests, noise evaluation procedures, matrix tests and acceptance criteria, brake noise analysis techniques, experimental modal analysis
Part 2 - “A Pragmatic Approach to Understanding the Mechanisms of Brake Judder and Noise”
- Discuss practical results and explanations to understand both cold & hot judder, typical pad deposition, corrosion, non-uniform film transfer, disc/rotor thickness variation (DTV or RTV), disc ripple, disc deformation (wavelike shape), hot spotting
- Topics include brake systems within the noise spectrum, typical modes of vibration of the component parts & pad loading. It continues with investigations and effects of disc/pad centre of pressure, disc/pad interface geometry to predict and alleviate potential noise issues, pad abutment, introducing asymmetry (binary flutter) and noise fix shims. The session explains why fixes work and considers design techniques to aid the NVH engineers
About the Tutors:
Prof. Dipl.-Ing. Holger Marschner
Holger Marschner is a Professor of Automotive Engineering and Noise, Vibration, Harshness (NVH) at the Frankfurt University of Applied Sciences (FRA-UAS).
After studying Mechanical Engineering at the Darmstadt University of Technology, he started working in 1996 at Continental Teves Frankfurt/Germany as a test engineer where he led the NVH department within the Hydraulic Brake Systems business unit for 15 years and in 2009, he was appointed Principal Technical Expert on NVH which allowed him to mentor on all issues around NVH in the Continental Automotive Group.
Prof. John Fieldhouse
John gained his BSc Honours (1st Class) at the University of Leeds in 1971 and his PhD in 1993. He is a member of the Society of Automotive Engineers and a Fellow of the Higher Education Academy where he was awarded a National Teaching Fellowship in 2008. He is also a Fellow of the Institution of Mechanical Engineers.
John is an active researcher and advisor to industry on brake related issues. He has been awarded the Dan Mahannah Award and the Lloyd L. Withrow Distinguished Speaker Award, both by SAE.
His interests include the education of automotive engineers – in particular promoting collaboration between industry and academia at an international level. He is also keen on engaging the young in the engineering disciplines and continues to teach vehicle performance at the University of Leeds. His research includes braking systems, NVH, teaching, and total vehicle emissions and related health hazards.
