Live Panel Discussion: Examining Automotive Megatrends - 'Connected, Autonomous, Shared and Electric' - and Their Impact on Noise, Vibration and Harshness (NVH) in the Vehicles of the Future

The megatrends in the automotive industry, such as electrification and lightweighting, pose fresh challenges for OEMs and component manufacturers as the lack of engine noise brings other noises to the forefront and the transition to multi-material lightweight structures causes new vibration issues. In addition, the many hybrid vehicle architectures mean unique NVH strategies need to be developed to mitigate noise and vibration for each of these configurations.

Join the industry’s leading experts to discuss:

  • What will be the impact of automotive megatrends (connected, autonomous, shared and electric) on NVH performance?
  • How is electric mobility presenting challenges in NVH performance in a range of vehicle types?
  • Developing an NVH technology roadmap for system level solutions (e.g. integrating components into powertrain systems) for next generation battery electric vehicle (BEV)/hybrid electric vehicle (HEV) programs

Live Panel Discussion: Designing NVH Packages for Lightweight, Multimaterial Vehicle Architectures in ICE, Hybrid and Electric Vehicle Configurations

The move to lighter vehicles, to improve fuel economy and range, poses several challenges when it comes to future vehicle architectures and managing noise and vibration. The increased adoption of lightweight materials such as aluminum and carbon composites in structural components such as body in white, chassis and doors, have the significant potential to degrade NVH performance. In addition, hybrid and fully electric vehicle configurations have considerable impact on the design of the NVH package; evident for example, in the influence of large, stiff battery packs in battery electric vehicles (BEVs) on NVH performance and drivability of EVs. In this session you will learn how to balance vibro-acoustic targets and weight reduction targets for all vehicle types – including steel, aluminum or composite bodies within internal combustion, hybrid or electric engines:

  • How can weight reduction be achieved through using lightweight multimaterials and how might they affect NVH performance within the vehicle?
  • What is the effect of powertrain and chassis mounting strategy on vehicle NVH?
  • How can vehicle design and mounting methods/designs aide to reduce vibration and noise of the powertrain mounting system?
  • What are the challenges associated with low frequency structure-borne noise generated by engine, driveline and road in different vehicle configurations?
  • How to best mitigate structure borne noise caused by battery packs in BEVs?
  • What is the benefit of using noise absorption and structural damping materials?
  • Assessing material offerings - e.g. polyurethane elastomer components – for mounts and isolators for chassis and powertrain applications (electric motors, battery packs, combustion engines)
  • Evaluating material performances based on sound frequency, material composition, thickness, finish and mounting methods.

Live Panel Discussion: Imagining Vehicle Cabins and Investigating Noise and Vibration Scenarios of the Future to Meet Customer Comfort and Entertainment Demands

In the not too distant future fully autonomous vehicles are likely to be on the road in closed areas such as city centers, airports, and universities. Traditional modes of ownership will change, and ride experience and perception of noise and vibration will need to be redefined. In the shift from driver to the passenger, consumer demands of comfort and entertainment requirements will become unique selling points and vehicle cabins and interiors will need to be redesigned to facilitate this change. In this panel discussion we will imagine the vehicle cabin of the future and investigate potential noise and vibration issues that might arise in these scenarios.
 
  • How will new mobility services (ride-hailing, autonomous vehicles) shape customers’ expectations for passenger ride comfort and acoustics?
  • What will be the features of the future vehicle cabin?
  • How to accommodate these features and how will interior NVH parts be affected by new passenger compartment configurations (flexible seating, proliferation of safety, comfort and entertainment accessories)?
  • What capabilities will the vehicles need to have to monitor their own “health” state – to recognize that service or repair is needed to identify degradation such as steering shimmy or brake fade, brake squeal, etc.?
  • New mobility concepts, such as car sharing, will require greater wear resistance and easily replaced interior components. Active sound design may also allow the interior vehicle noise to be tuned to the preferences of a current user – how will these properties be incorporated into NVH materials?

Live Panel Discussion: Effectively Measuring and Predicting Sound Quality of the Vehicle to Meet OEM NVH Standards on Consumer Comfort and Experience of Noise


Subjective rating scale is the universal automotive OEM measurement applied to indicating the consumer perspective of NVH. It is up to supplier to deduce objective measurements and requirements from the subjective requirements set by the OEMs. This can be challenging due to the different factors at play in the perception of noises and sound quality of the vehicle, such as the duration of the trip, road surface, etc. and targets can be unclear. The panel will investigate the challenges of effectively converting subjective customer expectations on drivability and sound quality into clear measurable standards. You can expect the following questions to be addressed:

  • How do OEMs set standards and how do they measure customer experience / customer requirements?
  • What are the challenges there in measuring perception of NVH?
  • How to derive objective requirements for development on how the noises should be within the vehicle?
  • Using simulation tools to determine sound quality of NVH early on in the development process
  • Which modelling and simulation methods are available and how to better estimate how noise gets from part to ear?
  • How to use advanced measurements and CAE methodologies to optimize mount design, locations, and properties for improved static, harmonic and transient behavior?
  • How are e-drive systems chassis changes impacting the transfer path of noise of steering systems, brakes, other parts etc.?
  • What are the technical capabilities available to maintain, or enhance, a vehicle’s NVH performance and address interior cabin noise?

Live Panel Discussion: Mitigating Source, Wind and Road Noise in Electric and Hybrid Vehicles for Improved Ride Comfort and Drivability

Development of new powertrain, steering, and braking systems with more advanced, lower noise technology whilst being cost-effective, and balancing energy efficiency of components with noise and vibration is a key challenge for Tier 1 manufacturers trying to meet the increasingly high demands of OEMs for better NVH performance as ride comfort and drivability becomes more important in the customer value proposition. In this panel discussion, you will hear how Tier 1s are working to minimize the noise or vibration produced by components through different design options; as well as OEM strategies to deal with NVH at the source:

  • How can vibration and noise of powertrain, drivetrain, ancillaries, steering and braking systems be optimized?
  • How much gain be gained through space and part packaging?
  • How to balance energy efficiency of system and noise and vibration?
  • How to manage high frequency noises emitted by electric vehicles systems and components?
  • What sound packaging technologies to adopt?
  • What are the performance requirements?
  • What are the control strategies of electronic equipment for better NVH performance?
