  1. 31. Polymer Aging Mechanics : An investigation on a Thermoset Polymer used in the Exterior Structure of a Heavy-duty Vehicle

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Basil Abu-Ragheef; [2019]
    Keywords : polyDicyclopentadiene; aging; thermosets; fatigue; mechanical properties; thermal fatigue; digital image correlation; viscoelasticity; polymer degradation; thermo-oxidation; photo-oxidation;

    Abstract : The use of plastic materials in the design of vehicle components is primarily driven by the need for vehicle weight and cost reduction. Additionally, these materials give design engineers freedom in creating appealing exterior designs. READ MORE

  3. 32. Spot-Weld Fatigue Optimization

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Filip Andersson; Rhodel Bengtsson; [2018]
    Keywords : ;

    Abstract : The purpose of this thesis project is to develop a methodology that can be used to minimize the number of spot-welds in a mechanical structure, this is done in a reliable manner via optimization methods. The optimization considers fatigue life in spot-welds and also stiffness and eigenfrequency values. READ MORE

  4. 33. Virtual Sensing for Fatigue Assessment of the Rautasjokk Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Sara Lundman; Patrick Parnéus; [2018]
    Keywords : Fatigue Assessment; Virtual Sensing; Steel Bridges; Eurocode; Field Monitoring; Finite Element Model;

    Abstract : This thesis treats virtual sensing for fatigue assessment of steel bridges. The purpose is to develop avirtual sensing method to use in the fatigue assessment process. The aim for the virtual sensing method is to only depend on strain measurements located on the bridge structure. READ MORE

  5. 34. Performance and Improvement Investigation of Accelerated Temperature Change Test.

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vandana Narri; [2018]
    Keywords : ;

    Abstract : This thesis is focused on Accelerated Temperature Change Test (ATCT). This test is performed in order to deteriorate and age a product in a faster than natural way. The ATCTs are primarily controlled with four parameters: the temperature range (∆T), ramp rate (RR), dwell time (DT) and number of cycles in test ( . READ MORE

  6. 35. Towards implementing collaborative robots within the automotive industry

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Niklas Land; [2018]
    Keywords : Collaborative robots;

    Abstract : Collaborative robots have many advantages and have proven to be useful, although there are still currently very few actual implementations of collaborative robots on the industrial shop-floors. One major reason for this is the high safety requirements within the industry and the difficulties to fulfil current safety regulations when using collaborative robots. READ MORE
