Abstract
This thesis describes the process of designing and developing a foldable motorized
micro-haulage vehicle, which follows the user, for urban transportation. The project
is made in collaboration with Volvo Car Corporation.
The transportation industry stands as a significant contributor to greenhouse
emissions. As a result, many efforts are being made to lower these emissions and
reach sustainability goals, hence why many transportation companies are shifting to
electric options. At the same time, urban spaces in cities are becoming more
congested which have environmental and social consequences. In response to
congestion, infrastructural changes are being made, such as limiting personal traffic
within certain areas and dedicated... (More)

congested which have environmental and social consequences. In response to
congestion, infrastructural changes are being made, such as limiting personal traffic
within certain areas and dedicated pedestrian-bike paths. With these goals and
changes in mind, new or alternative modes of transport are required for a more
sustainable future.
Through the use of the established product development process by Ulrich and
Eppinger, a conceptual vehicle was developed. The goal for the vehicle was to
encourage walking and aid users in personal haulage activities. While at the same
time keeping the vehicle low weight, foldable, sturdy and within size requirements.
Additionally, packaging of an electric powertrain should be incorporated, and
additive manufacturing (AM) should be explored to reduce the number of parts in
the vehicle.
The final version of the product was made entirely in CAD to visualize the product
concept digitally. Topology optimization was performed on the main critical part of
the vehicle, the skeleton, which through the use of AM could reduce the number of
parts simultaneously. The optimization yielded a weight reduction of 88% while
complying with stiffness requirements. (Less)
Abstract (Swedish)
Den här rapporten beskriver processen att designa och utveckla ett hopfällbart
motoriserat mikrotransportfordon, som följer användaren, för urban transport.
Projektet görs i samarbete med Volvo Car Corporation.
Transportindustrin står som en betydande bidragsgivare till växthusgasutsläpp. Som
ett resultat görs många ansträngningar för att minska dessa utsläpp och möta
hållbarhetsmål, varför många transportföretag övergår till elektriska alternativ.
Samtidigt blir urbana utrymmen i städer trängre, vilket har miljömässiga och sociala
konsekvenser. Som svar på trängsel görs infrastrukturella förändringar, till exempel
begränsning av persontrafik inom vissa områden och dedikerade gång- och
cykelbanor. Med dessa mål och förändringar i... (More)

Samtidigt blir urbana utrymmen i städer trängre, vilket har miljömässiga och sociala
konsekvenser. Som svar på trängsel görs infrastrukturella förändringar, till exempel
begränsning av persontrafik inom vissa områden och dedikerade gång- och
cykelbanor. Med dessa mål och förändringar i åtanke krävs nya eller alternativa
transportmedel för en mer hållbar framtid.
Genom att använda den etablerade produktutvecklingsprocessen av Ulrich och
Eppinger utvecklades ett konceptuellt fordon. Målet för fordonet var att uppmuntra
gång och hjälpa användare med personliga transportaktiviteter. Samtidigt som
fordonet håller låg vikt, hopfällbar, robust och inom storlekskrav. Dessutom ska
packningen av en elektrisk drivlina integreras, och additiv tillverkning ska utforskas
för att minska antalet delar i fordonet.
Den slutliga versionen av produkten gjordes helt i CAD för att visualisera
produktkonceptet digitalt. Topologioptimering utfördes på den viktigaste kritiska
delen av fordonet, skelettet, som genom användning av AM, samtidigt kunde
minska antalet delar. Optimeringen gav en viktminskning på 88% samtidigt som
man uppfyllde styvhetskraven. (Less)
