  1. 1. Experimental acceleration Measurements and Finite Elements Modeling

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Ibrahim Alnimairi; Salim Arrabi; [2021]
    Keywords : signal processing. PSD; mode shapes; Mdof; Sdof; PSDT-SVD; finite element modelling;

    Abstract : Heavy crushing machines under their production shifts, creates various levels of vibration, noise and dynamic forces which can be transferred to other parts of the industrial unit. Such kind of factors applies continuous forces on machine parts which can cause gradual fatigue, creep and eventually failure of machine. READ MORE

  2. 2. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

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

    Author : Johannes Jonsson; Anton Andersson; [2021]
    Keywords : Vibratory driving; sheet pile; Technology and Engineering;

    Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

  3. 3. Simulation and experimental study for vibration analysis on rotating machinery

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Mohd Shafiq Sharhan bin Zainal; [2020]
    Keywords : Multi Degree of Freedom MDOF ; Rotating machinery; Single Degree of Freedom SDOF ; Unbalance; Vibration analysis;

    Abstract : This student thesis aims to analyze the unbalance on rotating machinery by simulation and experimental. The machinery flywheel rotation is modelled as a Single Degree of Freedom (SDOF) and Multi Degree of Freedom (MDOF) system. The model rotation unbalance is simulated by MATLAB. Then the vibration measurement is taken by experimental. READ MORE

  4. 4. Horizontal natural frequency in a 10 story building : A comparison between CLT and concrete using estimate calculations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Jennifer Eriksson; [2018]
    Keywords : Horizontal natural frequency; tall timber building; timber structure; CLT; wind induced motion; tall CLT building; Horisontell egenfrekvens; hög träbyggnad; höga trähus; KL-trä; vindinducerade rörelser; högt KL-hus;

    Abstract : Tall slender buildings are easily set in motion by wind and earthquakes but by estimating the buildings horizontal natural frequencies in the design phase, these motions can be kept within acceptable boundaries. There are many parameters that decides the natural frequency of a building and it can therefore be difficult to calculate it. READ MORE

  5. 5. Modal analysis of pedestrian-induced torsional vibrations based on validated FE models

    University essay from KTH/Bro- och stålbyggnad

    Author : Simon Chamoun; Marwan Trabulsi; [2017]
    Keywords : Modal analysis; validated FE models; pedestrian-induced vibrations;

    Abstract : Finite element (FE) models serve as the base of many different types of analysis as e.g. dynamic analysis. Hence, obtaining FE models that represent the actual behaviour of real structures with great accuracy is of great importance. READ MORE
