  1. 1. Bearing condition monitoring : An investigation on the possibility of monitoring aging of the lubricating grease by means of acoustic emission and temperature.

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Dilesh Raj Shrestha; [2021]
    Keywords : Acoustic Emission; Fourier Transform; Infrared Spectroscopy; Condition Monitoring; Total Acidic Number; Fast Fourier Transform; Scanning Electron Microscopy; Rheology; Bleed Oil; Grease degradation;

    Abstract : Grease is among the most widely used lubricants in rolling element bearings. Proper understanding of the effect of lubrication due to grease aging can provide a significant increase in the life of the engineering systems. However, at present, there is no sufficient understanding of the grease aging effect in rolling elements bearing. READ MORE

  2. 2. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Balaji Srinivasan Venkatesan; [2020]
    Keywords : 1-D simulation; System simulation; ROMAX Energy; LMS AMESim; Power loss; Hypoid gear; Power Transfer Unit; Efficiency and Drag Loss Tests; 1-D simulering; systemsimulering; ROMAX Energy; LMS AMESim; effektförlust; hypoidväxel; kraftöverföringsenhet; effektivitet och dragförlusttester;

    Abstract : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

  3. 3. Drag Torque and Synchronization Modelling in a Dual Clutch Transmission

    University essay from Lunds universitet/Maskinelement

    Author : Mikael Lund; [2018]
    Keywords : drag torque; synchronization; dual clutch transmission; Technology and Engineering;

    Abstract : Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process.

  4. 4. Swedish Equity Sectors Risk Management with Commodities : Revisiting dynamic conditional correlations and hedge ratios

    University essay from Linköpings universitet/Nationalekonomi

    Author : Daniel Engström; Niklas Gustafsson; [2017]
    Keywords : Hedging; hedge; commodities; futures; hedge ratio; conditional correlation; DCC; GO-GARCH; DCC-GARCH; GARCH; Dynamic conditional correlation; oil; GSCI; copper; gold; safe haven; optimal hedge ratio; finance; economics; markets; risk; risk management; hedge effectiveness; Risk; riskhantering; råvaror; terminer; futures; hedging; hedge; GARCH;

    Abstract : The purpose of this study is to investigate changes in dynamic conditional correlations between Swedish equity sector indices and commodities using oil, gold, copper and a general commodity index. Additionally the purpose is to evaluate which of the two methods, DCC- GARCH or GO-GARCH that is more efficient in estimating correlation for hedge ratio calculation. READ MORE

  5. 5. Adsorption of Cr(VI) on Mill Scale

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Linus Köpberg; [2016]
    Keywords : ;

    Abstract : Mill scale is a by-product from hot rolling of steel. It has a high content of iron oxide which has the ability to adsorb ions. Hexavalent chromium is a pollutant which could be adsorbed to mill scale. Different pre-treatment of the mill scale was tested to optimize the adsorption of hexavalent chromium. READ MORE
