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 FMAKE SBO project MUSIC: Multi Sensor fusion for In-process Control.

Project
  • This PhD is part of a project aiming to produce first-time right zero- defect parts through additive manufacturing. This project aims to develop monitoring solutions fusing complementary information from optical sensors, and structural and airborne acoustic emission sensors. Given the complexity of combining different monitoring data streams, the project will employ data-driven models as well as physics-based signal analysis.

  • As a researcher you will develop a suite of modelling strategies that enable (i) determining the optimal sensor locations, (ii) accounting for varying vibro-acoustic signal travel time in complex parts and as the build progresses to synchronize this signal with the existing monitoring tools, and(iii) deconvoluting the measured vibro-acoustic signal to account for diffraction, reflection, or other effects that are interfering with the original signal as it travels from its origin (the melt or defect) to the sensor. Such a simulation supported approach to improve the accuracy of vibro-acoustic monitoring of Additive Manufacturing has not been previously developed.

  • The research is hosted by the Mecha(tro)nic System Dynamics division (LMSD), which currently counts >100 researchers and is part of the department of mechanical engineering of KU Leuven. The research group has a long track record of combining excellent fundamental academic research with industrially relevant applications, leading to dissemination in both highly ranked academic journals as well as at industrial fora. More information on the research group can be found on the website: https: // www. mech.kuleuven.be/en/research/mod/about and our linkedIn page: https: // www. linkedin.com/showcase/noise-&-vibration-research-group.

  • Profile

    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's 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 vibro-acoustic modelling and numerical simulation strategies, and/or I have a profound interest in these topics.

  • As a PhD researcher of the KU Leuven LMSD Division 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 from 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 in project meetings or at 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.

  • Offer
  • 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 4year 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 KULeuven 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 anon-academic context. More information on the training opportunities can be found on the following link: https: // set.kuleuven.be/phd/dopl/whytraining.

  • A stay in a vibrant environment in the heart of Europe. The university is located in Leuven, a town of approximately 100000 inhabitants, located close to Brussels (25km), and 20minutes by train from Brussels International Airport. This strategicpositioning 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).Further information can be found on the website of the university: https: // www. kuleuven.be/english/admissions/pdf/living-in-leuven- phd-18-november-2020.pdf
