6. On Derailment-Worthiness in Rail Vehicle Design : Analysis of vehicle features influencing derailment processes and consequences
Sammanfattning : This thesis aims at systematically studying the possibilities of minimizing devastating consequences of high-speed rail vehicle derailments by appropriate measures and features in the train design including the running gear. Firstly, an empirical database is established containing as much relevant information as possible of past incidents and accidents that have occurred at substantial running speeds due to mechanical failure close to the interface between the running gear and the track.

7. Life Cycle Energy Optimisation: A multidisciplinary engineering design optimisation framework for sustainable vehicle development
Sammanfattning : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.

8. Suspension design for off-road construction machines
Sammanfattning : Construction machines, also referred to as engineering vehicles or earth movers, are used in a variety of tasks related to infrastructure development and material handling. While modern construction machines represent a high level of sophistication in several areas, their suspension systems are generally rudimentary or even nonexistent. LÄS MER
9. Vehicle Conceptualisation, Compactness, and Subsystem Interaction : A network approach to design and analyse the complex interdependencies in vehicles
Sammanfattning : The conventional approach to vehicle design is restrictive, limited, andbiased. This often leads to sub-optimal utilisation of vehicle capabilities and allocated resources and ultimately entails the repercussions of designing andlater on an using an inefficient vehicle. LÄS MER
10. Designing for Change in Complex Systems : Design Considerations for Uptime in a Transportation System with Driverless Vehicles
Sammanfattning : The transportation system is undergoing a transformation to enable socially, environmentally, and economically sustainable transport solutions, and driverless trucks are considered one innovation that can contribute to a more sustainable and efficient transportation system. Nevertheless, introducing driverless trucks will cause disruptions in the system, and one considerable change is that the driver is no longer present. LÄS MER
