1. Aerolastic simulation of wind turbine dynamics
Sammanfattning : The work in this thesis deals with the development of an aeroelastic simulation tool for horizontal axis wind turbine applications. Horizontal axis wind turbines can experience significant time varying aerodynamic loads, potentially causing adverse effects on structures, mechanical components, and power production. LÄS MER
2. Modeling of Cold Pilgering of Tubes
Sammanfattning : Cold pilgering is a challenging tube forming process in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. LÄS MER
3. Numerical simulation of shape rolling
Sammanfattning : In the first part of this thesis, the FE program MSC.Marc is applied for coupled thermomechanical simulations of wire-rod rolling. In order to predict material behaviour of an AISI 302 stainless steel at high strain rates generated during wire-rod rolling, a material model based on dislocation density is applied. LÄS MER
4. Surface and Inner Deformation during Shape Rolling of High Speed Steels
Sammanfattning : Shape rolling is a common manufacturing process used to produce long products i.e. bars and wire. One of the problems that might occur during rolling is defect formation leading to rejection of the finished product. LÄS MER
5. Simulation of Stainless Steel Tube Extrusion
Sammanfattning : The simulation of hot extrusion processes is a difficult and challenging problem in process modeling. This is due to very large deformations, high strain rates and large temperature changes during the process. LÄS MER
