Automotive Powertrain Noise, Vibration and Harshness (NVH)

Automotive Powertrain Noise, Vibration and Harshness (NVH)

Automotive powertrain Noise, Vibration and Harshness (NVH) issues are in the forefront due to the increased power output and powertrain downsizing.

Our Aim

In the era of powertrain downsizing and electrification there is an urgent need for robust and broadband solutions to tackle vehicle’s Noise, Vibration and Harshness (NVH). Our aim is to understand the fundamentals of powertrain NVH issues by focusing on their root causes in order to develop novel and robust design solutions for the automotive industry.

Our approach comprises:

  1. state of the art powertrain modelling techniques at system and component levels, involving different scales of motion and multiphysics features
  2. validation of the modelling outcomes by experimental measurements in situ (vehicle level) as well as in the Laboratory

Our Research

The Dynamics Research Group in the Wolfson School of Mechanical, Electrical and Manufacturing Engineering at Loughborough University have many years’ of experience in studying complex automotive powertrain NVH issues. Examples of ongoing projects include the study of transient clutch dynamics, the development of nonlinear vibration absorbers for torsional oscillations, as well as the NVH of Electric Powertrains.

Our Outcomes

The Dynamics Research Group has completed numerous research projects in collaboration with various industry partners. Key research projects and related outcomes are summarised here:

  • EPSRC funded Doctoral Training Partnership (DTP) programme (in collaboration with industry): “Simulation of Transient Wear in Elastohydrodynamic Contacts of Gears”. (Ongoing).
