  1. 1. Numerical study of the effect of thermal ice loads on concrete dams

    University essay from KTH/Betongbyggnad

    Author : Imal Zuwak; Wasseem Kordoghly; [2020]
    Keywords : Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Abstract : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. READ MORE

  3. 2. Development of Active Safety Systems for Rollover Prevention of All-Terrain Vehicles

    University essay from KTH/Fordonsdynamik

    Author : Erfan Nikyar; Vishal Venkatachalam; [2018]
    Keywords : ;

    Abstract : The sales of all-terrain vehicles (ATVs) are increasing year by year, especially in countries like Sweden, Australia and New Zealand. With the increase in sales, a proportional rise in number of accidents involving all-terrain vehicles is also evident. Of these accidents the major cause was identified as rollover occurrence.

  4. 3. Effekt av grusmängd och vältning för spårbildning på grusväg

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Oscar Gustafsson; [2015]
    Keywords : GPR; skogsbilväg; virkesbil; FWD; roadscanner; forest road; timber truck;

    Abstract : Nybyggnation och underhåll av skogsbilvägar medför stora kostnader för skogsbruket. Georadar (GPR) är en teknik som kan användas för att läsa av en vägs struktur vilket ger ett möjligt tillvägagångssätt för att reducera kostnader vid upprustning av vägar. READ MORE

  5. 4. FE analysis of interlocking C3C solid concrete blocks without casting

    University essay from Institutionen för teknik, TEK

    Author : Emina Deumic; Damir Sadic; [2011]
    Keywords : Concrete blocks; Retaining wall; Temporary construction; Overturning; Finite Element Model; Betongblock; Stödmur; Tillfälliga konstruktioner; Vältning; Finita Element Modell;

    Abstract : Solid concrete Lego blocks can be used as temporary retaining wall systems or as wall separators between different materials such as sand, salt, compost, etc. The advantage of concrete blocks is that you can create temporary constructions. It is easy to move or expand the constructions when no casting is required between the blocks.

  6. 5. Implementing and studying the effects of a roll stability system in heavy vehicles using a moving simulator

    University essay from Fordonssystem

    Author : Ulrika Pettersson; [2010]
    Keywords : rollover; roll stability; simulator;

    Abstract : This thesis presents the making and the implementation of a roll stability system for a simulator truck. The purpose of the system is to prevent rollover. The making of the system consists of three parts; calculating the roll angle, calculating a rollover index and constructing the control system. READ MORE
