On the use of a combined numerical/experimental approach for dynamic health monitoring of mechatronic systems. KU Leuven
Rotating components and rotating machinery play a key role in the dynamics of several mechatronic system.In the current state-of-the-use, rotating machinery fault detection, diagnosis and identification are usually based on vibration measurements. Unfortunately, In many practical situations, it is not possible to measure directly those system quantities that are more sensitive to the investigated fault, due to lack of space or dedicated ...
Modeling, Optimal Control and HVAC Design of Large Buildings using Ground Source Heat Pump Systems KU Leuven
Since May 2010, the directive 2010/31/EU of the European Parliament compels its Member States to drastically decrease the energy use of buildings, to increase their energy efficiency and to increase the relative amount of renewable energy they use. One of the technologies recommended by the directive is the heat pump which efficiently uses electricity to extract thermal energy from a heat or cold source. In this work, buildings equipped with ...
Adaptive model reduction strategies for fast prediction and optimization of the vibro-acoustic performance of dynamical systems with damping KU Leuven
Over the past years, the dynamic and acoustic qualities of products have become an increasingly important design criterion in many industrial sectors. Moreover, in order to improve the cost-efficiency of products, lightweight designs are emerging. However, their high stiffness-to-mass ratio can often be the cause of noise and vibration problems. Therefore, it is customary to use complex damping materials such as viscoelastic and porous ...
Virtual Sensing for Vehicle Dynamics: a Model-based Approach for Indirect Measurement of the Vehicle Motion States and Tyre Forces KU Leuven
This research aims at developing model-based estimators for the vehicle motion states and tyre forces that are robust to uncertain tyre/road conditions and use only measurements available in modern production vehicles. Such estimators would provide invaluable information to enhance vehicle dynamics control systems and would facilitate the development of future control systems such as autonomous driving. This work combines the use of ...
Adaptive Direct Search for Single- and Multi-Objective Black-Box Optimization KU Leuven
With the growth of computational power in the last decades, the penetration of numerical methods in engineering workflows has drastically increased. Advanced design and analysis programs have become standard tools in the engineering practice. Concurrently, the state of the art in numerical optimization has also been steadily advancing. Given the close interconnection between engineering and optimization, it is no surprise that the trend ...
Vibro-acoustic Resonant Metamaterials: from Concept to Engineering Solution KU Leuven
In recent decades, resonant metamaterials have attracted attention as a novel lightweight noise and vibration insulation solution for the hard-to-address low-frequency region, albeit in well-defined frequency ranges called stop bands. These stop bands are frequency regions without free wave propagation, in which high noise and vibration insulation is obtained. They are created by a Fano-type interference, which arises due to the addition of ...
User-centric design of automatic lameness detection in dairy cattle KU Leuven
Lameness is an important health problem causing severe welfare deteriorations and economic losses up to € 53 per cow per year in dairy cattle. Timely detection and treatment can help to minimize economic losses and preserve cow welfare. Current visual detection methods are labor intensive and subjective, and require training to allow detection of subtle changes in a cow’s gait. As a result, the problem is underestimated in practice, and ...
Phased Geometrical Acoustics using Low / High Frequency Reflection Coefficients with Applications to Absorption Measurements KU Leuven
The prediction of sound and noise in everyday environments is of utmost importance for comfort as well as for personal health. Although measurements give invaluable information about the behavior of existing environments, designers and engineers are also in need of predictive models that are both accurate and efficient. These simulations provide detailed analysis before construction or prior to renovations and thus yield a huge return on ...
Advanced bearing modelling for the numerical analysis of system-level machine dynamics KU Leuven
The last few decades have seen a growing trend towards lightweight and high performance mechanical systems. Meanwhile, the average time-to-market has been drastically reduced. These recent developments are driving the manufacturer's need to predict the dynamic machine behaviour more accurately and at an early design stage. Due to the advent of modern computational capabilities, numerical simulation tools can be used for this ...
