  1. 21. Test and refinement of a down-scaled actively suspended forwarder

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Qingxiao An; [2016]
    Keywords : Scaled vehicle; pendulum arm suspension; rough ground test; Nedskalat fordon; pendelarmsfjädring; ojämn mark; provning;

    Abstract : Cut-To-Length (CTL) logging is the dominating logging method in many parts of the world. CTL logging requires a forwarder for the logs from the felling area to a landing area. Due to the harsh off-road working conditions, a well performed suspension system is necessary for the forwarder. READ MORE

  3. 22. Control of Leaning Dynamics for Three-wheeled Vehicles : Experimental evaluation of two control strategies

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : ROBERT GRÖNING; GUSTAV STEN; [2016]
    Keywords : ;

    Abstract : Three‐wheelers are popular in fuel efficient contests but do not see much commercial success. This could be because three‐wheelers are easier to tip over than four wheeled vehicles. One way to counteract the tipping over is to introduce leaning dynamics on three‐wheeled vehicles so that they lean in corners like bicycles and motorcycles can. READ MORE

  4. 23. Modelling and Dynamic Simulation of Tracked Forwarder in Adams ATV Module

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Praveen Ramachandran; [2015]
    Keywords : racked Forwarder; Multi-body simulation; MSC. Adams ATV; Template Based Modelling; Bandskotare; Flerkroppssimulering; MSC Adams ATV; Mallbaserad modellering;

    Abstract : Swedish forest industry is relying on the cut-to-length method for logging and there has always been a constant quest to make it more efficient and sustainable. Reduction of forest soil damage and operator vibration dosages are crucial steps that could facilitate meeting the above stated targets. READ MORE

  5. 24. Cost Evaluation of Seismic Load Resistant Structures Based on the Ductility Classes in Eurocode 8

    University essay from KTH/Betongbyggnad

    Author : Georgios Valdemar Drivas; [2014]

    Abstract : Most people do not associate Scandinavia with seismic activity and earthquakes; however, there is in fact seismic activity in the region. Although in comparison with southern Europe the return periods of earthquakes with large magnitudes are quite long, itis critical to consider earthquake impact when designing structures. READ MORE

    Abstract : Economic development and growing integration process of world trade increases the demand for road transport. In 2008, the freight transportation by road in Sweden reached 42 million tonne-kilometers. Sweden has a tradition of long and heavy trucks combinations. Lots of larger vehicles, with a maximum length of 25. READ MORE
