Particle damper modelling for vibration control

Abstract

Engineering has for a long time been confronted with the problem of structural vibrations which has the possibility of compromising the operations and safety of many systems and structures. A new class of passive vibration control systems known as particle dampers has emerged as a possible solution to these oscillations and enhance the structure. This thesis focuses on the particle damper modelling by employing the ANSYS computational tools and stresses on the comparable method that considers the balance between model precision and computational efficiency. The method of the research is based on the creation of the accurate particle damper models where the boundary conditions, geometrical representation and material characteristics are set to reproduce the behaviour observed in the real world. The behaviour of the particles and the structure is analysed dynamically through transient analysis and the interaction between the particles and the structure under various stress conditions is studied. Besides shedding light on previously unknown scenarios, in which particles violate boundary boundaries, the thesis reveals significant findings on the behaviour of particle dampers, especially under seismic forces. This result underlines the significance of accurate definition of boundary conditions and constraints for modelling. The finding has potential applications in a wide range of future studies in the areas of fluid-structure interactions, real-time control strategies, advanced particle dynamics modelling, and machine learning. The practical applications offer the possibility of developing more accurate and efficient structural vibration control systems in aerospace and architecture fields. In conclusion, this thesis is a significant step towards achieving the objective of understanding and mastering ANSYS particle damper modelling and has the potential to revolutionise the field of structural dynamics by enhancing the safety and force bearing capacity of structures.
