6. On efficient and adaptive modelling of friction damping in bladed disks
Sammanfattning : This work focuses on efficient modelling and adaptive control of friction damping in bladed disks. To efficiently simulate the friction contact, a full-3D time-discrete contact model is reformulated and an analytical expression for the Jacobian matrix is derived that reduces the computation time drastically with respect to the classical finite difference method.

7. Advances In Heavy Vehicle Dynamics with Focus on Engine Mounts and Individual Front Suspension
Sammanfattning : The main objective of the research presented in this thesis is to enhance driver comfort and handling of a heavy truck that in turn leads to better vehicle safety and stability. The focus has been put on studying two suspension systems of the truck, engine and front axle suspensions, due to their significant impact on the dynamic performance of the vehicle. LÄS MER
8. Rotordynamic Modeling and Characterization of Support Elements in Vertical Machines
Sammanfattning : The dynamic properties of rotating machines are highly influenced by interconnecting devices, such as bearings, seals, or squeeze-film dampers. They play a significant role in regulating the characteristics of the interaction between the rotating and stationary parts of the machines. LÄS MER
9. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques
Sammanfattning : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. LÄS MER
