  2. 1. On modally distributed damping in heavy vehicles

    Author : Peter Holen; Annika Stensson Trigell; Zbigniew Lozia; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; damping; modal damping; chassis suspension; heavy vehicle; attachment compliance; Physics; Fysik;

    Abstract : This thesis investigates passive damping system performance in heavy vehicles through analytical expressions, simulations with different vehicle models as well as through experimental evaluation in a tractor semi trailer combination. The objective is to study what levels of chassis suspension damping that are desirable for different vehicle modes and how this may be achieved with passive damping systems. READ MORE

  4. 2. Suspended forestry machines for sustainable forestry

    Author : Abbos Ismoilov; Ulf Sellgren; Kjell Andersson; Viktor Berbyuk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Abstract : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. READ MORE

  5. 3. Active Engine Vibration Isolation using Feedback Control

    Author : Claes Olsson; Ahmed El-Bahrawy; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Broad band active vibration isolation of automobile engine using linear and nonlinear feedback control is considered. The objective is to reduce the forces transmitted to the chassis and body, and, thus, reducing vibrations and structure borne noise inside the vehicle compartment when the engine is subjected to different excitations.

  6. 4. Motion modelling and control strategies of over-actuated vehicles

    Author : Johannes Edrén; Annika Stensson Trigell; Jenny Jerrelind; Mats Jonasson; Dongpu Cao; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the growing concern for environmental change and uncertain oil resources, the development of new vehicle concepts will in many cases include full or partial electric propulsion. The introduction of more advanced powertrains enables vehicles that can be controlled with a variety of electric actuators, such as wheel hub motors and individual steering. READ MORE
