  3. 7. Washing Machine Design Optimization Based on Dynamics Modeling

    Författare :Thomas Nygårds; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experiments; Multiobjective Optimization; Modeling; Vibration dynamics; Washing machine; Suspensions; Semi-active control.; Automatic balancing;

    Sammanfattning : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

  5. 9. Hushållsproduktion och föräldraledighet : Att städa, tvätta och laga mat - med och utan barn

    Författare :Johanna Forssell; Anita Nyberg; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; household production; everyday life; division of labour; parental leave; allocation of time; household work; cleaning; cooking; washing; föräldraledighet; hushållsarbete; familjen; arbetsfördelning; hemmet; vardagslivet; tid; Sverige; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : When it comes to cleaning, cooking and washing, having a child means that the demand for resources increases for the household to be able to uphold the same standards with the same production methods, as at the time before having a child. At the same time one of the parents will be able to spend more time on household production during parental leave. LÄS MER

  7. 10. Precipitation and separation of lignin from kraft black liquor

    Författare :Fredrik Öhman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pressing; filtration; washing; lignin; separation; precipitation; black liquor; extraction;

    Sammanfattning : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. LÄS MER
