Elastomer Use in Electric Vehicles

This afternoon technical discussion meeting (ATDM) examined the use of elastomers when used with electric powered vehicles.

This event was the first ever online discussion meeting in light of the Covid-19 imposed travel and social distancing restrictions. 

This afternoon technical discussion meeting (ATDM) examined the use of elastomers when used with electric powered vehicles. It included a discussion of the different materials requirements as well as the changes to design of rubber components that are used in suspension systems and drive-train in electric vehicles. 

This event was free to attend due to the generous RIEG sponsorship from ARTIS.

13:30 Introduction - Prof James Busfield (QMUL)
Ludovica Caliano

Elastomer requirements for electric vehicles (2MB pdf) - Ludovica Caliano (presenter) & Aranzazu Guisuraga - (Exxon Butyl Polymers, Belgium)

Recyclability, light weighting and tire rolling resistance for improved EV performance and energy efficiency. Mobility is changing around the world and disruptive trends continue to shape the future of vehicles. In this discussion, two elastomers: SantopreneTM TPV and ExxproTM 3563 specialty elastomer were proposed as novel solutions enabling step-out performance of the next generation electric vehicle. 

Marco Poggi

Challenges Associated with Mounting System Design for EV Applications (0.5 MB pdf) - Marco Poggi & Matt Maunder - (Ricardo, UK)

Ricardo has extensive experience of powertrain mounting systems for internal combustion engines. This has been extended to build a process to optimise powertrain mounting systems for electric vehicles, where the focus is now on prioritising modal tuning and torque reaction capability, accounting for flexible powertrain behaviour, whilst deemphasising the isolation of torque recoil vibrations.

Joe Hallett

Using Carbon Black to Meet the Design Challenges of EV Applications (2MB pdf) - Joe Hallett (presenter) - (Birla Carbon, USA & UK)

The drive to improve vehicle efficiency and the move to electrification has created new challenges for suppliers of elastomeric components to the automotive industry. Light-weighting has increased galvanic corrosion due to the move to Magnesium and Aluminium alloys and electrification has changed the NVH requirements. This talk addressed both challenges and identified potential solutions.

Will Mars

Digital Twin Prototype and Concept for EV Mount Integrity Monitoring (1MB pdf) - Will Mars - (Endurica, USA)

Advances in sensing and computing technology generate an opportunity to track the structural integrity of elastomer mounts in service with application to EV maintenance and diagnostics. This talk will demonstrate, using a live demo, how elastomer products with real lifetime strain histories, material nonlinearities, updated fatigue states can be modelled in real time.
