  2. 1. Modelling and simulation of pantograph-catenary dynamics

    Author : Lars Drugge; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : 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. READ MORE

  5. 3. Driver Preferences of Steering Characteristics

    Author : Markus Agebro; Annika Stensson; Lars Drugge; Christopher Patten; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Driver preferences; Steering characteristics; Steering systems; Driving simulator experiments; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : 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. READ MORE

  6. 4. Exploring force allocation control of over actuated vehicles

    Author : Johannes Edrén; Annika Stensson Trigell; Jenny Jerrelind; Lars Drugge; Jonas Fredriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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.

  7. 5. Towards efficient vehicle dynamics development : From subjective assessments to objective metrics, from physical to virtual testing

    Author : Gaspar Gil Gómez; Mikael Nybacka; Lars Drugge; Egbert Bakker; Peter Pfeffer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steering feel; vehicle handling; driver preference; objective metrics; subjective assessments; regression analysis; artificial neural network; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : 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. READ MORE
