The KU Leuven Mecha(tro)nic System Dynamics division (LMSD) is searching for a research engineer to join its team to work in the challenging ToleDO (Tolerance Design Optimization) strategic basic research project.Project.This PhD is part of a project aiming to develop a novel approach towards assessing the influence various manufacturing tolerances have on mechanical system operation. Designing tolerances can be a time-intensive and heuristic process in mechanical designs. Often these tolerances are simply copied from previous designs or obtained from rather heuristic tolerance synthesis methods, which do not account for the actual behavior of an assembly nor do they take into account the production cost. In other cases, designers even lack the freedom to alter the tolerances, and need to stick to company standards. This is problematic as these tolerances can have a major impact on the performance, wear, etc. of the system while also strongly affecting the cost of manufacturing and quality control. This project will focus on the development of a workflow and a process chain to (semi-automatically) obtain designs with key tolerances in mechanical systems to enable an effective trade-off between the desired performance and production cost, or which offer consistent operational performance under given tolerances.As a researcher you will investigate novel methods to evaluate the impact of tolerances on mechanical performance through flexible multibody simulation. This is aimed to achieve much lower computational loads than what is currently possible through conventional finite-element approaches. You will leverage this computational gain to exploit these models in a design context where both optimal tolerance allocation, as well as tolerance robust design can be considered.


If you recognize yourself in the story below, then you have the profile that fits the project and the research group.

  • I have a master degree in engineering, physics or mathematics and performed above average in comparison to my peers.
  • I am proficient in written and spoken English.
  • During my courses or prior professional activities, I have gathered some basic experience with numerical modelling methods and optimization methods.
  • I have notions about multibody and finite-element simulation
  • I am proficient in programming basic methods in Matlab.
  • As a PhD researcher of the KU Leuven Noise and Vibration Research Group I perform research in a structured and scientifically sound manner. I read technical papers, understand the nuances between different theories and implement and improve methodologies myself.
  • Based on interactions and discussions with my supervisors and the colleagues in my team, I set up and update a plan of approach for the upcoming 1 to 3 months to work towards my research goals. I work with a sufficient degree of independence to follow my plan and achieve the goals. I indicate timely when deviations of the plan are required, if goals cannot be met or if I want to discuss intermediate results or issues.
  • In frequent reporting, varying between weekly to monthly, I show the results that I have obtained and I give a well-founded interpretation of those results. I iterate on my work and my approach based on the feedback of my supervisors which steer the direction of my research.
  • I feel comfortable to work as a team member and I am eager to share my results to inspire and being inspired by my colleagues.
  • I value being part of a large research group which is well connected to the machine and transportation industry and I am eager to learn how academic research can be linked to industrial innovation roadmaps.
  • During my PhD I want to grow towards following up the project that I am involved in and representing the research group on project meetings or conferences. I see these events as an occasion to disseminate my work to an audience of international experts and research colleagues, and to learn about the larger context of my research and the research project.
  • A remuneration package competitive with industry standards in Belgium, a country with a high quality of life and excellent health care system.
  • An opportunity to pursue a PhD in Mechanical Engineering, typically a 4 year trajectory, in a stimulating and ambitious research environment.
  • Ample occasions to develop yourself in a scientific and/or an industrial direction. Besides opportunities offered by the research group, further doctoral training for PhD candidates is provided in the framework of the KU Leuven Arenberg Doctoral School (https://set.kuleuven.be/phd), known for its strong focus on both future scientists and scientifically trained professionals who will valorise their doctoral expertise and competences in a non-academic context. More information on the training opportunities can be found on the following link: https://set.kuleuven.be/phd/do...;
  • A stay in a vibrant environment in the hearth of Europe. The university is located in Leuven, a town of approximately 100000 inhabitants, located close to Brussels (25km), and 20 minutes by train from Brussels International Airport. This strategic positioning and the strong presence of the university, international research centers, and industry, lead to a safe town with high quality of life, welcome to non-Dutch speaking people and with ample opportunities for social and sport activities. The mixture of cultures and research fields are some of the ingredients making the university of Leuven the most innovative university in Europe (https://nieuws.kuleuven.be/en/content/2018/ku-leuven-once-again-tops-reuters-ranking-of-europes-most-innovative-universities).
