Prediction of Diffuse Vibration Transmission across Complex Plate Junctions KU Leuven
More and more people are living in cities and urban areas where noise pollution can strongly affect them. Reducing the noise people experience indoors can be achieved by providing a sufficiently high sound insulation. Sound insulation predictions are often complex since design details, variations in workmanship and variations in material properties can have a significant influence. Furthermore, multiple sound transmission paths can be ...
Condition monitoring under varying operating and environmental conditions KU Leuven
Vibration-based condition monitoring plays a lead role in fault detection in bearings and gears. In the case of gearboxes, gears (as long as they are in contact, without backlash) usually provide a strong periodic signal at their meshing frequency (and its harmonics) masking the usually weak signals emitted by faulty bearings, which are random signals due to the fact that the rolling element movement presents slip. Bearing signals are often ...
Vision based reduced order modeling approach for operational parameter identification of nonlinear dynamic finite element models KU Leuven
Accurate dynamic identification of mechanical components is key to fully exploit the potential of Digital Twins of mechanical systems. However, current state-of-the-art dynamic parameter identification methods do not allow the use of high-spatial density measurements for components under operational conditions. The focus of this project is to develop a framework for identifying these operational parameters for detailed nonlinear dynamic ...
Experimental Dynamic Substructuring: Towards Robust FRF-based Decoupling Strategies KU Leuven
Wind turbine manufacturers and their suppliers are faced with increasing constraints on the noise and vibration requirements of their products, while development time and costs are under pressure. One of the problems in the current development is the end-of-line validation of prototype gearboxes. It is observed that the strict limits imposed on the end-of-line test rig do not always lead to acceptable vibration levels when the gearboxes are ...
Computational damage identification and propagation in complex composite structures: Efficient and robust damage detection and diagnosis. KU Leuven
Houyu Lu’ work will focus on developing a new comprehensive computational scheme for critical, online decision making for optimal condition-based maintenance of safety critical composites. Nowadays the transport sector operates at a fixed-interval, conservative maintenance strategy which reduces the availability of the structural product (e.g. aircraft) with simultaneous costs for the operator and passengers worldwide. The proposed project ...
Research on the Hydrodynamic Characteristics Analysis and Optimization Design of a Rim-driven Thruster KU Leuven
In conventional shaft-driven propulsion systems, the shaft has to be connected to the main engine by another intermediate transmission device, in which way too much space is taken up. Moreover, the complex structure causes great mechanical loss, resulting in low efficiency and creating high vibrations and noise. On the contrary, the rapidly developing rim-driven thruster (RDT) is gaining more and more popularity in recent years. Comparing ...

Precious Prompts: developing an innovative just-in-time adaptive prompt-based intervention aimed at interrupting prolonged bouts of sedentary behavior in older adults Ghent University
Considering the rapid growth of the global aging population, healthy aging has become a key priority of the World Health Organization. Healthy aging can be promoted by targeting health behaviors, such as sedentary behavior. A promising way to disrupt sedentary behavior, is to bring this automatic behavior and its context into conscious awareness by providing point-of-choice prompts to stand or move. However, in previous prompt-based ...

IoBaLeT: Sustainable Internet of Battery-Less Things
1) Summary of scientific goals IoBaLeT aims to bring the performance (i.e. throughput, scalability and range) of battery-less IoT networks on-par with its battery-powered counterparts, by enabling active rather than passive communications and computing. An end-to-end networking ...
