  1. 1. On modally distributed damping in heavy vehicles

    University dissertation from Stockholm : KTH

    Author : Peter Holen; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; damping; modal damping; chassis suspension; heavy vehicle; attachment compliance; NATURAL SCIENCES Physics; NATURVETENSKAP 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

  2. 2. Improving Machining System Performance through designed-in Damping Modelling, Analysis and Design Solutions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lorenzo Daghini; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Abstract : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. READ MORE

  3. 3. A study of active-passive damping treatments

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hélène Illaire; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active vibration control; damping mechanisms; active constrained layers;

    Abstract : Active Constrained Layer (ACL) treatment is a vibration-damping treatment which consists of a viscoelastic layer constrained by an actuator. It dissipates energy simultaneously by the shearing of the viscoelastic layer and by the action of the actuator. READ MORE
