DTU, Department of Mechanical Engineering, Section for Solid Mechanics invites highly motivated and talented applications for a 3-year PhD position dealing with “Contact dynamics for micro acoustic devices”. The PhD project will be financed under the framework of CAMM (Centre for Acoustic-Mechanical Microsystems) - a multidisciplinary research centre running in collaboration with DTU Departments of Mechanical Engineering and Electrical Engineering and financially supported by three Hearing Aid companies from Denmark.

The research fields covered by the multidisciplinary PhD project span scientific areas such as contact mechanics, mechanical vibrations, vibroacoustics as well as numerical and experimental methods in mechanics. The goal of the PhD project is to develop a novel approach for tackling the challenging problem of analysing and tailoring highly uncertain contact conditions between various mechanical parts in microacoustic devices such as hearing aids. This may include the development of new theoretical contact models and numerical procedures as well as novel approaches to the design of mechanical parts with contact conditions. Experimental validation of the developed theory and procedures is an integrated part of the project.

Responsibilities and tasks
Your research task will include:

  • Identify state of the art numerical methods for analysing contact mechanics and assess these methods’ applicability to dynamic analysis of microacoustic devices.
  • Implement a numerical model for accurate and efficient prediction of the vibrational response.
  • Plan and carry out experiments for validation of numerical predictions.
  • Assess the variability in the vibrational response due to uncertainty of the contact conditions.
  • Developing a strategy for improving the predictability of the vibrational response of microacoustic devices.

Furthermore:

  • You are expected to contribute to DTU’s collaborations with the Danish Hearing Aid companies and help in the knowledge transfer from DTU to the CAMM’s industrial partners
  • You will engage in DTU’s teaching activities and supervise Bachelor and Master Project students
  • You will be responsible for the systematic planning and following up on your research project, compiling and storing your scientific data, and to ensure the scientific integrity of your research
  • You will participate in international conferences, compose scientific manuscripts for publications, and take part in outreach activities

As a PhD student in CAMM, you will:

  • Be a part of a creative and stimulating scientific environment
  • Develop your theoretical and experimental skills
  • Collaborate with experts in topics related to your project

We offer an interesting and challenging job in an international atmosphere with the focus on research, teaching, innovation, and scientific advice for the benefit of society. We offer a position with great flexibility, and we emphasize work-life balance. In the area of technical and natural sciences, DTU is one of the leading research and education institutions in Europe.

Qualifications
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree in engineering, physics, material science, or related fields. Documented experience with mechanical vibrations, vibroacoustics, finite element analysis or related numerical methods, etc. will help in the positive evaluation. Preference will also be given to candidates who can document their ability for scientific publications. We also expect that:

  • You have the ability to focus and to achieve ambitious goals
  • You are willing to develop any required skills and knowledge
  • You are proactive and a good team player
  • You have excellent communication skills in English - both written and spoken
