1. Semi-active suspension seats in High speed crafts
Master-uppsats, KTH/Marina systemSammanfattning : The working environment of a high-speed-craft (HSC) can be uncomfortable and hazardous for the crew and passengers on board. This due to the repeated exposure to high levels of vibration and shocks, that can lead to reduced performance and severe injuries to the back and neck. LÄS MER
2. Multi-objective optimization and performance evaluation of active, semi-active and passive suspensions for forestry machines
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : The development of forestry machines is currently heading towards new solutions that reduce their impact on the environment and in particular on the soft forest soil in which the machines operate. The terrain conditions that forestry machines encounter in their regular duties can be very rough, and if the vehicle-ground interaction is not properly controlled cumulative damage can progressively aggravate these conditions and potentially render a route or a zone impracticable, apart from causing a detrimental effect in the forest environment.

3. Modellering av Åkkomforten i en Skotare
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Sammanfattning Denna avhandling avser en Skotare – Valmet 860,4 – från Komatsu Forest, som har hög produktivitet, men saknar såväl primärt fjädringssystem för fram- och bakaxel som hyttfjädringssystem för att isolera mot vibrationer från ojämnt underlag. Tidigare projekt har praktiskt mätt upp accelerationer (vibrationer) i förarstol, hytt, framvagn och bakvagn, liksom fyra boggievinklar. LÄS MER
