PhD position on the prediction of noise and vibration transmission in buildings - Belgium  

Company managed [?] Still accepting applications

Posted on : 10 April 2017

Project Description

  • An important way of protecting people from noise is by ensuring a sufficient overall sound insulation in buildings.
  •  However, this is a complex problem since multiple transmission paths are important, uncertainties can have a large effect, acoustic performance requirements often conflict with structural and thermal requirements, and accurate vibro-acoustic modelling with currently available numerical prediction tools requires a huge computational effort.
  •  An efficient yet sufficiently accurate prediction framework for the acoustic design of building systems is therefore needed, taking all relevant uncertainties into account and opening up the way for model-based optimization. For the development of this framework, a prestigious Starting Grant has been awarded by the European Research Council (ERC).
  • This PhD forms a vital part of the ERC project.
  •  The aim of the PhD is to develop an efficient yet sufficiently accurate numerical method for predicting the transmission of vibrations across realistic, complex junctions between building elements. This type of transmission very often limits the overall sound insulation performance of a building system. 
  • The targeted development will involve the exploration and hybridization of advanced methods and modelling concepts in elastodynamics, including finite element and boundary element techniques and modern statistical energy analysis.
  •  Since the robustness of the method will be a crucial aspect, its development will also involve quantifying the combined effect of all uncertain parameters in a logically consistent and computationally efficient way.
  • Based on these numerical and statistical developments, robust structural junction types of high performance will be designed, implemented and tested.

  • The successful applicant is soon to obtain or has obtained a MSc degree (or equivalent) in Civil or Mechanical Engineering or a closely related field.
  •  A solid background and demonstrable interest in structural mechanics and finite element modelling are essential.
  •  He or she will show good communication skills, good programming skills, proficiency in English, and a strong motivation towards completing a PhD within four years.

  • We offer a collaborative and internationally oriented research environment at one of the leading engineering faculties worldwide as well as a PhD scholarship of about 1900 euro per month (net income, the exact amount depends on family situation). 
  • The successful candidate will be encouraged to present his or her research at international conferences and he or she can benefit from our strong international research network.
  •  Besides the main research activities, the successful candidate will also act as a teaching assistant for one or more courses related to structural mechanics. 
  • Depending on background, he or she may need to pass a pre-doctoral test (e.g. selected courses and presentation of research plan) prior to being allowed to the PhD program.
