Sammanfattning : This thesis considers theoretical and experimental investigations of the dynamic behaviour of pantograph-catenary systems for trains and its relation to simulation driven product development. The pantograph and catenary form an oscillating system that is coupled via the contact force between the pantograph head and the contact wire. LÄS MER

Sammanfattning : The future of vehicle steering systems lies within by-wire technology. With by-wire technology mechanical or hydraulic systems are replaced by electronic systems. Removal of the steering column and possibly other linkage and gears yields vast potential of further improvement of performance, comfort and safety. LÄS MER
Sammanfattning : As the concern for environmental changes and diminishing oil resources grows more and more, the trend of new vehicle concepts now includes full electric or partly electric propulsion systems. The introduction of electric power sources enables more advanced motion control systems due to electrification of the vehicle's actuators, such as individual wheel steering and in wheel hub motors.

5. Towards efficient vehicle dynamics development : From subjective assessments to objective metrics, from physical to virtual testing
Sammanfattning : Vehicle dynamics development is strongly based on subjective assessments (SA) of vehicle prototypes, which is expensive and time consuming. Consequently, in the age of computer- aided engineering (CAE), there is a drive towards reducing this dependency on physical test- ing. LÄS MER
