Syfte – Studiens syfte är att öka kunskapen om hur fordonstillverkares affärsmodeller påverkas vid förändring av statliga regelverk genom att studera ett framtida införande av HCT i Sverige. HCT, High Capacity Transports, är ett samlingsnamn för lastbilar som är tyngre och/eller längre än vad gällande lagstiftning tillåter. Regelförändringen övervägs för att sänka kostnader och miljöpåverkan.  Metod – Arbetet har genomförts i form av en case-studie. För att studera påverkan på både fordonstillverkares och åkeriers affärsmodeller har intervjuer genomförts med varuägare, åkerier och förare inom fjärrtransporter av styckegods. Detta har kompletterats med löpande kontakt med uppdragsgivande fordonstillverkare samt deltagande i konferenser inom ramen för det nationella HCT-arbetet.  Resultat – Inget större modalskifte mellan järnvägs- och landsvägstransporter förväntas eftersom järnvägens infrastruktur styr transportvalet och inte påverkas av ett HCT-tillåtande. Vidare riskerar fordonstillverkare att sälja färre lastbilar vid ett tillåtande av HCT men genom anpassning av affärsmodellen kan de öka värdet per fordon. Detta värde kan ökas genom att sänka kundernas driftkostnad, maximera fordonens drifttid och föra kundens talan mot myndigheter.  Praktiskt bidrag – Studien har resulterat i ett nytt affärsmodellsramverk för fordonstillverkare vid införande av HCT. Ramverket visar att samtliga nuvarande värdeområden bör inkluderas i kommande affärsmodell och att flertalet får ökad betydelse. På grund av nya förutsättningar blir vissa av dessa områden dessutom svårare att uppnå samtidigt som nya områden kan läggas till.  Vetenskapligt bidrag – Genom att öka kunskapen om affärsmodellspåverkan vid förändring av statliga regelverk utvidgar studien befintlig teori om förändringar av affärsmodeller. Studien belyser även vikten av att studera hela leverantörskedjan vid sådana förändringar. Detta eftersom statliga regelverk styr förutsättningarna för flera aktörer med starka inbördes relationer. Därmed sprider sig effekterna av en regelverksförändring till övriga aktörer i kedjan. / Purpose – The purpose of this study is to increase the knowledge about how legislative changes affect the business model of vehicle manufactures by studying a future allowance of HCT in Sweden. HCT, High Capacity Transports, is a generic term for trucks exceeding today’s weight and/or length regulations. Reasons for implementing HCT include reducing costs and environmental consequences. Method – Effects of legislative changes have been studied through a case-study of how HCT would affect the Swedish transport system. In order to study business model implications for both vehicle manufactures and hauliers, interviews have been held with transport buyers, hauliers and drivers within long distance haulage of break bulk cargo. This has been complemented by continuous contact with the commissioning vehicle manufacturer and participation in HCT conferences. Findings – Findings indicate that there will be no major modal shift between railway and road since the railway infrastructure determines the modal choice and is unaffected by HCT. Furthermore findings show that vehicle manufactures risk to sell fewer vehicles in case of HCT allowance but a business model adaption can increase the value per vehicle. This can be achieved by reducing customer operating costs, increasing vehicle uptime and being the voice of the customer against authorities. Practical implications – The study has resulted in a HCT business model framework for vehicle manufactures. The framework shows that all present value areas should be included in a future business model and that several areas will increase in importance. In the effect of new conditions several areas will become more difficult to fulfill. Furthermore new areas will be added. Theoretical implications – This study expands current theories within business model changes by increasing knowledge about how legislative changes affect business models. Furthermore this study highlights the importance of studying the whole supply chain in the event of these changes. The reason for this is that legislations affect the conditions for several players with strong peer relationships. Thereby effects due to changed legislations will spread to other players in the chain.

Godstransporter ökar i takt med att utrikeshandeln växer, vilket bidrar till utsläpp av växthusgaser. Hållbar utveckling och miljö är viktiga faktorer i dagens samhälle vilket gör att det ställs krav på nya och innovativa transportlösningar. Ett alternativ att bemöta dessa krav är genom högkapacitetstranporter, som i dagsläget testas, utförs och forskas kring frekvent i Sverige. Högkapacitetstransport avser lastbilsfordon som är längre och/eller tyngre än dagens konventionella lastbil som har fått dispens att trafikera vissa zoner på det svenska vägnätet. Denna studie baseras på att utvärdera två intermodala transportlösningar för transport av gods på sträckan mellan Göteborgs hamn och Viared, Borås. Den ena transportlösningen baseras på högkapacitetstransport och den andra baseras på en järnvägsbaserad transportlösning. De alternativa transportlösningarna utvärderas med avseende på effektivitet omfattande transportkostnad, flexibilitet och tid samt miljöpåverkan omfattande koldioxidutsläpp genom en fallstudie.Slutsatserna har resulterat i att högkapacitetstransport genererar en högre transporteffektivitet jämfört med dagens dragbil som trafikerar den utpekade vägsträckan i fallstudien. I brist på material har inga konkreta kostnader kunnat beräknats för de olika transportlösningarna. Däremot kunde en slutsats dras kring att de alternativa transportlösningarna ej bör uppgå till en högre kostnad än vad dagens transportlösning genererar. Ur miljösynpunkt har koldioxidutsläpp för de olika transportlösningarna beräknats. Implementeras hela vägsträckan med högkapacitetstransport har resultatet gällande koldioxidutsläpp genererat i en minskning med 30,6 procent jämfört med dagens dragbil. Däremot visade studien att järnvägstransporten vinner miljömässiga fördelar då den jämfört med dragbilen som trafikerar vägsträckan idag reducerar utsläppen med 80,4 procent. Dock visar koldioxidutsläppet i den intermodala järnvägslösningen att vägtransporterna bidrar med 98 procent av utsläppen.Denna studie väger för- och nackdelar gentemot varandra för en implementering av högkapacitetstransport. Högkapacitetstransporten jämförs även gentemot järnvägens för- och nackdelar vid transport av containergods. Studien bidrar dessutom till att stärka och reflektera över tidigare publicerade studier som finns inom ämnet. / Freight transport increases as foreign trade grows, which contributes to greenhouse gas emission. Sustainable development and the environment are important factors in today's society, which imposes demands on new and innovative transport solutions. One way of meeting these demands is through high capacity transports, which are currently being tested, performed and researched frequently in Sweden. High capacity transport refers to truck vehicles that are longer and/or heavier than today's conventional truck that has been given the dispensation to traffic certain areas on the Swedish road network. This study is based on evaluating two intermodal transport solutions for the carriage of goods on the route between Port of Gothenburg and Viared, Borås. One transport solution is based on high capacity transport and the other is based on a rail-based transport solution. Through a case study, the alternative transport solutions are evaluated based on efficiency, including transportation costs, flexibility and time, and the environmental impact including CO2 emissions.The conclusions have resulted in high capacity transport generating a higher transport efficiency compared with today's truck that operates the designated road distance in the case study. In lack of material, no concrete costs have been calculated for the various transport solutions. On the other hand, a conclusion could be drawn that alternative transport solutions should not be at a higher cost than today's transport solution results in. From an environmental point of view, CO2 emissions for the various transport solutions have been calculated. Implementing the entire road haulage with high capacity transport has resulted in a reduction of CO2 emissions by 30,6 percent compared to the current truck. On the other hand, the study showed that rail transport wins environmental benefits, as compared to the truck that carries the route today, emissions reduce by 80,4 percent. However, CO2 emissions in the intermodal railroad solution show that road transport contributes 98 percent of emissions.This study weighs strengths and weaknesses towards each other for the implementation of high capacity transport on the designated route. High capacity transport is also set against the railroad with pros and cons of transporting container goods. The study also contributes to strengthening and reflecting the theory from previously published studies within the subject.

Soil suction is one of the main state parameters that governs unsaturated soil behaviour. Tensiometers are the only type of probe that can measure soil suction directly, but only up to 90 kPa. In the past two decades, a new type of tensiometer with much greater measurement range (up to 2 MPa) has appeared in the literature. The measurement range (i.e. capacity) of a tensiometer is limited by (i) how well it is saturated, and (ii) the air entry value of its porous interface. In this study, the first high capacity tensiometer of Turkey was designed and built. For the purpose of increasing the measurement capacity of the tensiometers, a novel saturation setup that uses a hydraulic pressurization system with capacity of 10 MPa was designed and built. A vacuum-and-pressure saturation procedure was developed. To calibrate the 10 MPa pressure transducers that form the core of the tensiometers, a high-pressure calibration setup capable of pressurizing up to 11 MPa was designed and built. By varying designs of tensiometer bodies, porous interfaces and seals, ways of increasing the suction capacity are investigated. Over a dozen tensiometer design variations are developed, and tried by exposing to atmospheric evaporation. A maximum suction measurement of 870 kPa was achieved with a conventional design / however, none of the new designs were successful. 3 successful designs were also briefly tried on soil samples

I dagens samhälle spelar miljön en viktig roll, både för hur miljön skall bevaras och hur miljöproblem kan undvikas. Med detta uppmanas allt fler människor ha en större miljömedvetenhet. Miljöproblemet är ytterst märkbart i infrastrukturen och främst transporter av dess olika slag. Större fordon, såsom lastbilar, färdas långa sträckor för att transportera gods som i sin tur ökar bränsleförbrukning och gör att utsläppen blir allt mer. Genom att öka lasten, per transporterad enhet, på de tyngre fordonen så kan bränsleförbrukningen minskas. Företaget Parator Industri AB som tillverkar lastbilstrailers är med i ett HCT-projekt (High Capacity Transport) där de tillsammans med andra involverade företag ska ta fram en ny konstruktion av tyngre fordon med ett hållbarhetstänk.Syftet med detta examensarbete är att är att ta fram en lösning för kombination av en lastbil med kopplat släp vilket senare kommer utgöra produktionsunderlaget till företaget Parator. Detta genom att hjälpa företaget konstruera en ny DUO-trailern som kommer bestå av två chassin som ska sammanfogas och som kommer transportera containrar med gods i. Genom aktionsforskning med fokus på intervjuer och observationer, har vetenskapliga källor samlats in. Detta kombineras med modellering på dataprogrammet SolidWorks där 3D-modellering av den nya konstruktionen utförs. Med överslagsberäkning beräknas hållfastheten fram på den nya trailerns infästningar. Även ett nytt produktionsunderlag, med tillhörande materiallista och ritningar har tagits fram i rapporten. Studien har vidare analyserat huruvida de tillämpade tillverkningsmetoderna samt monteringar kan vara hållbara ur ett produktionsperspektiv. / Today the environment is a common question and how to reduce emissions into nature. With this more people are encouraged to have an environmental mindset. Mostly the environmental damage comes from the transport with different kinds of vehicles and their exhaust gas. Larger vehicles, such as trucks, travel long distances to deliver goods which increases fuel consumption and increases emissions. By increasing the load, per transported unit on the heavier vehicles, fuel consumption can be reduced. The company Parator Industry AB that designs truck-trailers is involved in an HCT-project (High Capacity Transport) together with other companies where the goal for the company is to achieve a more sustainable production material and have less impact on nature.The purpose of this study is to find a solution for a combination of the truck connected with a trailer which will later form the production basis for the company Parator. This by helping the company design a new DUO-trailer which will consist of two chassis to be joined and will transport containers with goods. Through action research with a focus on interviews and observations, scientific sources can be collected. This will be combined with modeling on the computer program SolidWorks where 3Dmodeling of the new design is performed.Estimated value of the design is done for the new attachments. The study also contains a production base with produced drawings and material list. The study also analyzes the relevance of the calculated values and if they will be sustainable in the future.
