1. Distributed vehicle testing : dynamic simulation for automotive winter testing
Sammanfattning : Today, rather than provide parts similar to their competitors and rely on one or two automakers, successful automotive component suppliers focus heavily on innovation and collaboration with several manufacturers in a global market. In this thesis, an as-is scenario for automotive winter testing is presented. LÄS MER
2. Model calibration methods for mechanical systems with local nonlinearities
Sammanfattning : Most modern product development utilizes computational models. With increasing demands on reducing the product development lead-time, it becomes more important to improve the accuracy and efficiency of simulations. LÄS MER
3. Railway wheel steel behaviour upon thermo-mechanical loadings
Sammanfattning : Optimised railway maintenance techniques such as rail grinding and milling, or rail repair welding, are vital to more sustainable rail networks. As demands on the railway increases, the need to better understand the material behaviour during local heating events occurring during maintenance is amplified. LÄS MER
4. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications
Sammanfattning : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.
