1. Heavy Vehicle Maintenance in an Industrial Network Perspective: Implications of Embeddedness and Interdependencies
Sammanfattning : Road transport solutions are often complex and involve numerous stakeholders. To secure that goods arrive in a timely and efficient manner, companies must cooperate and interact to define, implement and operate the transport solutions required. LÄS MER
2. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels
Sammanfattning : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. LÄS MER
3. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance
Sammanfattning : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. LÄS MER
4. Onboard condition monitoring of vehicle-track dynamic interaction using machine learning : Enabling the railway industry’s digital transformation
Sammanfattning : The railway sector’s reliability, availability, maintainability, and safety (RAMS) can significantly improve by adopting condition based maintenance (CBM). In the CBM regime, maintenance decisions are driven by condition monitoring (CM) of the asset. LÄS MER
5. Design of Multifunctional Body Panels for Conflicting Structural and Acoustic Requirements in Automotive Applications
Sammanfattning : Over the past century, the automobile has become an integral part of society, with vastincreases in safety, refinement, and complexity, but most unfortunately in mass. Thetrend of increasing mass cannot be maintained in the face of increasingly stringentregulations on fuel consumption and emissions. LÄS MER
