  1. 1. Investigation of torsion modes in overhead traveling cranes: : Reviewing the ISO 22980 standard

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Simon Jens; [2023]
    Keywords : Overhead traveling crane; Finite element method; Frequency and experimental vibration analysis; Travers; finita elementmetod; egenfrekvensanalys; experimentell vibrationsanalys;

    Abstract : Overhead cranes and rail mountings in the wall are subjected to vibrations whenlifting equipment. The purpose of this thesis is to review if the minimum frequencyvalue for cranes, according to the ISO 22986:2007 standard is conservative whendesigning overhead traveling cranes. READ MORE

  3. 2. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    University essay from KTH/Teknisk akustik

    Author : Oscar Lundin; [2022]
    Keywords : Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Abstract : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. READ MORE

  4. 3. 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

  5. 4. HSI effects on pedestrian bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Giancarlo Costa; [2021]
    Keywords : Dynamics; HSI; Human Structure Interaction; pedestrian bridge;

    Abstract : The study on Human Structure Interaction (HSI) effects represent a new research field in the design of pedestrian bridges. The presence of pedestrians on the structure affects the dynamic properties of the bridge, and these changes may be quantified in order to design pedestrian bridges in a more efficient way.
