The Wolfson School of Mechanical, Electrical and Manufacturing Engineering at Loughborough University has a long-established record in automotive powertrain engineering. The Dynamics Research Group is engaged in numerous activities, being widely known for their contributions in numerical and experimental research applied to powertrains, tribodynamics of automotive systems, drivetrain engineering and Noise, Vibration and Harshness phenomena.
Full Project Detail:

The research project aims to investigate the root causes of Noise, Vibration and Harshness (NVH) phenomena in e-powertrains (Electric Vehicles), as generated and amplified by the interactions of the electric motor with the drivetrain. The e-powertrain dynamics will be studied under typical transient (as well as steady state, periodic) operating conditions from a system perspective, in collaboration with Automotive OEM.

Numerical models (virtual prototypes) of the powertrain comprising the electric motor and drivetrain subsystems will be developed, using commercial software and custom-made subroutines. Attention will be made on introducing the effects of local nonlinearities and component flexibility. The models will be validated experimentally in the laboratory. Model validation against experimental measurements obtained from an e-powertrain will be also conducted (pending to a case study availability). The importance of critical design system parameters on e-powertrain NVH will be evaluated and innovative solutions will be sought.
