Overview

This 3-year fully funded PhD project will address the gaps in knowledge and capability in understanding and modelling the mutual effects between vibration and friction across different scales. The application of this research will be focused on aerospace jointed structures and vibration assisted decommission technologies in wind turbine industrials.

Project Details

Overall, the world consumes 20% of its energy to overcome friction in various systems and another 3% to maintain wear-related failures.

Friction can be found in almost all engineering systems such as jointed structure, braking systems in automotive and railway, and drilling systems in oil & gas industries.

This PhD project will address the gaps in knowledge and capability in understanding and modelling the mutual effects between vibration and friction across different scales. The mutual effects mainly refer to the presence of friction will influence the dynamic response, but simultaneously the generated vibration will alter the friction force again.

The specific objectives are to:

  • develop a multi-scale modelling framework to understand and predict the effects of micro/meso/macro scale friction interface on dynamical response with different applied vibration loads
  • experimentally validate this numerical tool through existing test rigs available in universities or academic partners

The application of this research will be focused on aerospace jointed structures and vibration-assisted decommission technologies. The project will be in close collaboration with TU Delft and National Manufacturing Institute Scotland. Mutual visits and placements will be arranged during the programme.

The study will be undertaken in the Aerospace Centre of Excellence within Department of Mechanical and Aerospace Engineering at Strathclyde. The student will take part in Strathclyde Researcher Development Programme and Doctoral Training School to develop their research and professional skills throughout the PhD study such as the PGCert in Researcher Professional Development.

The project will also provide training in nonlinear dynamics and tribology through courses in the department and national workshops as well as research placement through our project partners National Manufacturing institute Scotland and TU Delft.

The student will also have chances to attend relevant international conference, visits and industrial workshops to enhance their communication and presentation skills and abilities to collaborate with researchers in this field.

Funding details

The successful candidate will be fully-funded for 3 years with ‘home’ fee and stipend at the UKRI Doctoral Stipend rate (approximately £16,000 annually) from 1 Oct 2022.

Eligibility

The applicant should:

  • hold at least a second class upper division (2.1) BEng /MSc degree, or equivalent, in aerospace/mechanical engineering
  • have strong interests and related background in mathematical modelling, software development, computational mechanicals and mechanical/aerospace engineering
  • be very passionate in science and engineering
  • have good writing and presentation skills
