Development of Efficient Models of Frictionally Induced Vibrations for the Prediction of Automotive Brake Squeal.

   Faculty of Engineering and Informatics

About the Project

Brake squeal continues to be a problem for vehicle manufacturers, generating noise pollution, customer dissatisfaction and significant warranty claims. With the introduction of quieter hybrid and electric vehicles the issue of brake squeal presents new challenges in the achievement of lower acceptable noise limits under new use case scenarios, whilst the task of understanding and explaining the underlying phenomenon remains.

This PhD project focusses on the development of source and response models of frictionally induced instabilities in order to advance the knowledge of this complex phenomenon. New efficient numerical models for the prediction of brake squeal will be developed for the purpose of being used by vehicle manufacturers. Experimental investigations will be performed using advanced experimental facilities within the Braking Research Centre at the university and will explore and examine the many theories and mechanisms in order to achieve experimental verification and validation using purpose built laboratory dynamometers. The research will be supported by staff with extensive background within the braking and wider automotive industry.

Applications are invited from candidates with a background in mechanical and/or automotive engineering.
