1. A study of hierarchical FE solutions of Biot's equations for acoustic modeing of poroelastic medial
Sammanfattning : .... LÄS MER
2. Hierarchical finite element modelling of Biot's equations for vibro-acoustic modelling of layered poroelastic media
Sammanfattning : This thesis concerns three-dimensional finite element modelling of Biot's equations for elasto-acoustic modelling of wave propagation in layered media including porous elastic materials. The concept of hierarchical (p-version) finite elements are combined with various weak forms of Biot's equations. LÄS MER
3. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches
Sammanfattning : The objective of the present work is to study the vehicle suspension as a vibro-acoustic system of high complexity, consisting of many sub-systems with fundamentally different acoustical properties. In a parallel numerical and experimental modelling effort, important contributions to the understanding of its behaviour have been achieved. LÄS MER
4. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems
Sammanfattning : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. LÄS MER
