1. Variation Simulation Customized for Composites by Including FEM Simulations of Orthotropic Lamina
Sammanfattning : The use of composite materials is increasing in many fields of production. Composite manufacturing, as well as other fields of production, suffers from uncertainties resulting in products that deviate from the specification. Geometry assurance is a common procedure used to keep the variations in product assemblies under control. LÄS MER
2. Visualizing the Effects of Geometrical Variation on Perceived Quality in Early Phases
Sammanfattning : In a perfect world, geometrical variation in a manufacturing process would not exist. Every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
3. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases
Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
4. Engine Encapsulation for Increased Fuel Efficiency of Road Vehicles
Sammanfattning : Thermal engine encapsulation is an increasingly popular design choice, which insulates the engine from the external environment and retains heat in the engine after it is turned off. This decelerates motor cool-down and increases the probability for high initial temperature at a subsequent engine start, resulting in shorter warm-up and reduced friction between engine parts.

5. Flow Maldistribution in Exhaust Aftertreatment Systems - Numerical Simulations
Sammanfattning : To comply with the stringent emission norms under every driving condition, including the coldstart conditions and Real Driving Emissions (RDE) tests, accurate models that capture the spatial and temporal variation of flow distribution information in Exhaust AfterTreatment Systems (EATS) are required. This study is aimed at characterizing and quantifying flow distribution in EATS under transient conditions with realistic geometry that illustrates the complex nature of the flow conditions. LÄS MER
