There is growing interest in using electric motors as prime movers in mobile hydraulic systems. This increases the interest in so-called pump-controlled systems, where each actuator has its own drive unit. Such architectures are primarily appealing in applications where energy efficiency is important and electric recuperation is relevant. An issue ...
Detta examensarbete har ämnat konstruktionen av en strimlare för att sönderdela kasserad PLA-plast från 3d-skrivarna i verkstaden på Mälardalens universitet. Målet med detta arbete var att underlätta återvinning men även möjliggöra återbruk av materialet genom att skapa nytt filament av den sönderdelade plasten som åter kan användas av 3d-skrivarna...
Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. This PhD thesis st...

Digitalization is forcing the industry to rethink current practices in all business domains, pushing for a digital transformation of business and operations at a high rate and, thus, paving the way for new business models and making others redundant. For small and medium-sized companies (SME), in particular, it is an enormous challenge to keep up w...
Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. Due to exceptionally high rotational velocities, these types of impacts involve blade deformation at high strain rates...
Detta examensarbete utfördes för Scania CV AB. Huvudfokus för arbetet var att analysera sambandet mellan tätningsytors beskaffenhet och uppkomst av mikroläckage i tätningsförband. Tätningsområdet mellan motorblock och cylinderfoder i Scanias V8–motor valdes att undersökas för att analysera möjligheten till att förbättra dagens kravställning till en...
Background: When a potential customer reaches out to NKT and requests themto tender an offer for a project, NKT will start to compile the information neededfor the customer to make an informed decision. Among others, one document thatis included in the information is a CSO. This drawing displays an overview of thecomplete cable installation, which ...
Background. At the year of 2021, 770 million people worldwide were living without access to electricity. In parallel with this, electrification of vehicles and other equipment constantly increases which results in a demand for access to reliable off-grid energy to allow for operation in remote locations or places without sufficient energy infrastru...
