11. Models for Life Cycle Cost Estimation of Spare and Wear Parts for Urban Gondola Lift Systems : A Case Study
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälleSammanfattning : Urban gondola lift systems are becoming a regular sight rather than a rarity throughout the globe. Authors attribute their increasing popularity to factors such as environmental sustainability, operational reliability and cost efficiency compared to other right-of-way transit solutions. LÄS MER
12. Energy flow model for a scrapper conveyor unit
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : Värmevärden AB is an energy company that distributes district heating. One of their challenges today is to reduce the energy losses and wear that occur in the plant's scrapper conveyor unit. The conveyor belt is in constant motion whether it is transporting fuel or going unloaded at idle. LÄS MER
13. Development of a Laboratory Test Method for Assessment of Crater Wear Volume on Inserts for Steel Turning
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : This thesis project was carried out at Sandvik Coromant in Västberga, Sweden with the purpose of developing a new laboratory test method for volumetric assessment of crater wear on inserts for steel turning. The test method was developed with the Sandvik Coromant´s existing crater wear measurement method as a starting point. LÄS MER
14. System-wide LCC Calculation for Novel Brake Block Material in Nordic Condition
Master-uppsats, KTH/MWL Marcus Wallenberg LaboratorietSammanfattning : One of the main issues of cast-iron block brake material is high noise. Nowadays, train operators tend to change the brake block material from cast-iron to composite material. However, composite block brake materials are likely to produce more wear than cast-iron block brakes, degrading the dynamic behavior of the vehicle on the track. LÄS MER
15. Införande av BK4 : Bärighetsberäkning av balkbro med lång spännvidd
M1-uppsats, KTH/Byggteknik och designSammanfattning : Regeringen har på förslag att införa en ny bärighetsklass för det svenska vägnätet. Den föreslagna bärighetsklassen får beteckningen BK4 och innebär att maximal bruttovikt för lastbilar ökas från nuvarande 64 ton till 74 ton. LÄS MER
