  1. 1. Vibration analysis for condition monitoring of mechanical presses

    University essay from Lunds universitet/Industriell Produktion

    Author : Julia Runesson; [2019]
    Keywords : Vibration analysis; Predictive maintenance; Condition monitoring; Mechanical press; Press maintenance; PSD; DFT FFT; RMS; Kurtosis; Technology and Engineering;

    Abstract : In a world where the concept of just-in-time has been lifted outside of the manu-facturing world and onto the market, the increasing demand of luxury wares like cars is accompanied only by tougher industrial conditions and no room for error. Loss of productivity and decrease in efficiency can be devastating to any manufac-turing company in today’s market climate. READ MORE

  2. 2. Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Eric Ceccarelli; [2019]
    Keywords : Density functional theory; DFT; Hubbard-Holstein; Hubbard-Holstein model; HH; Quantum transport; Physics and Astronomy;

    Abstract : Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. READ MORE

  3. 3. Conceptual Dynamic Analysis of a Vehicle Body

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Björn Pedersen; [2018]
    Keywords : Technology and Engineering;

    Abstract : The noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicle development process. READ MORE

  4. 4. Fretting tests on connector terminals

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Marcus Magnusson; [2018]
    Keywords : Fretting; Corrosion; Laser vibrometry; Connector; Vibration; Technology and Engineering;

    Abstract : Fretting is a complex set of mechanical and electrical mechanics that occurs at the contact surface between two vibrating objects. It is widely present in electrical connectors close to combustion engines due to the constant exposure to vibrations. Fretting is an extensive problem in the automotive industry but little research is done. READ MORE

  5. 5. Reduction of vibration transmitted through car seats : A study to reduce test drivers’ whole-body vibrations at Volvo Car Group’s test facility

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Malin Fellenius; [2017]
    Keywords : Ergonomics; Front seat; Whole-body vibration;

    Abstract : Present thesis will concentrate on the attention to reduce the input of whole-body vibrations transmitted to test drivers in durability tests. On behalf of Volvo Cars, the purpose has been to develop a concept solution on the driver's seat. Solving this problem is significant due to test driver’s safety and theirs ergonomically conditions.
