1. Lindström, Björn. Metodik för analys av batteriets laddningscykel i entreprenadmaskiner : Prototypbyggnad och teori.

Degree: Engineering and Physics, 2015, Karlstad University

Volvo Construction Equipment AB, Volvo CE, är en global tillverkare av entreprenadmaskiner. Detta exjobb fokuserar på batterierna i dessa entreprenadmaskiner som försörjer maskinens elsystem och startmotor vid start. Med dagens teknik ställs nya krav på strömförsörjning i entreprenadmaskiner. Den största skillnaden är att förbrukare är igång när motorn är avstängd och strömförsörjningen kommer enbart från batteriet. Ett startbatteri av bly-syra typ är inte konstruerad för detta användningsfall. Volvo CE jobbar därför med att ta fram kunskap om hur laddningen i batterierna används och cyklas under drift. Frågeställning om vilka parametrar och trender som är relevanta för att utvärdera batteriladdning har behandlats i detta arbete. Bakomliggande teori har undersökts, förklarats och vidareutvecklats i beskrivningen av den föreslagna metodiken för analys av batteriladdningsnivå i entreprenadmaskiner. En metod för hur identifierad relevant mätdata skall extraheras ur entreprenadmaskinerna har beskrivits i samband med beskrivningen av den utvecklade och framtagna prototyputrustningen. Den i detta arbete föreslagna analysmetodiken för dimensionering av batterikapacitet och tillämpad på mätdata från batteriladdningen under driftsmässiga förhållanden för entreprenadmaskiner kan också hjälpa till att ge svar på om de batterier som idag används av Volvo CE är lämpliga i den nya generationens entreprenadmaskiner. Arbetet innehåller ett nyhetsvärde för Volvo CE och andra då den föreslagna analysmetodiken inte beskrivits eller tillämpats tidigare på Volvo CE. Arbetet ger också förslag på hur man kan gå vidare i kunskapsuppbyggnaden och utvecklingsarbetet kring batterier inom Volvo CE.

Volvo Construction Equipment AB, Volvo CE, is a global producer of construction machines. This thesis has focus on the battery in these machines that are providing power to the electrical system and start engine during cranking. With today’s technology there are new demands on the power supply in construction machines. The largest difference is in the demand for power when the engine is off and the only power source is the battery. A Lead-Acid starter battery is not constructed for this type of demand. Because of this Volvo CE has begun to build knowledge about how the charge in the battery is used and cycled during usage. This thesis has processed questions about which parameters and trends that are relevant to evaluate regarding the level of charge in the battery. The theory behind these parameters has been examined, described and evolved in the suggested methodology for analysis of the level of charge in the battery in construction machines. A method on how to extract identified data from the construction machines has been described in the work on the prototype equipment for collecting the data. The suggested methodology in this thesis to analyse the level of charge in the battery in construction equipment based on the user case may help to give answer to the question if the…

3. Winqvist, David. Augmenting communication channels toward the evolution of autonomous construction sites.

Degree: 2016, , Department of Mechanical Engineering

Context In the last centuries, we have been generating and building infrastructure at a faster pace than ever before. Simultaneously the costs for labor and construction sectors as road and house building is increasing. This provides room for autonomous machines. The development of infrastructure is accomplished through highly efficient and productive construction machinery that progressively modernizes to form the society. In order to increase the pace of development, both cars and industry are getting more and more automated. Volvo Construction Equipment is exploring the autonomous vehicle space. The new machines complement and perfect the human work with efficiency, reliability, and durability. There is however, a question of trust between the human workers and the autonomous machines, I will in this thesis investigate methods on how to develop trust through communication systems with autonomous machines.   Objectives To create recommendations and solutions for products that build trust between human and automated machines on a construction site.   Method Outcome is reached through a case study exploration with validated learning, meaning that it will incorporate learnings through prototype iterations.   Results The result evaluates how trust could be developed between humans and autonomous machinery at a construction site and how communication methods between these parties could be implemented while maintaining high levels of efficiency and safety.   Conclusion Findings in this thesis indicates that trust is developed over time with reliable systems that provide colleagues with updated information available at any time. The results can be introduced in both today’s and tomorrow’s construction sites at various levels of advanced technology.

Sammanhang De senaste hundra åren har vi gett upphov till att bygga infrastruktur i en snabbare takt än någonsin tidigare. Samtidigt ökar kostnaderna för både arbetskraft och byggsektorer som väg- och bostadsbyggnader. Denna situation ger utrymme för autonoma maskiner. Utvecklingen av infrastruktur sker genom effektiva och produktiva konstruktionsmaskiner som successivt moderniseras för att forma samhället. För att öka utvecklingstakten moderniseras både bilar och industri för att möta en mer automatiserad vardag.  Volvo Construction Equipment undersöker det autonoma fordonsutrymmet för nästa generations maskiner. Automationen kompletterar de nya maskinerna och fulländar det mänskliga arbetet med effektivitet, tillförlitlighet och hållbarhet.   Det finns dock en fråga om relationen mellan mänskliga arbetare och autonoma maskiner, jag kommer i denna avhandling undersöka metoder för hur man kan utveckla tillit genom kommunikationssystem mellan arbetare och autonoma maskiner.   Mål Att skapa rekommendationer och lösningar…
