  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. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors

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

    Author : Johannes Jonasson; Olle Karlsson; [2022]
    Keywords : hardwood; birch; beech; clt; cross-laminated timber; vibrations; floors; footfall; accelerations; Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. READ MORE

  4. 3. Investigation of Vibration in Electrical Circuit used in Maritime Applications

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Babak Rouhani; [2022]
    Keywords : Mechanics; Vibration; Modal analysis; Electronic equipment; Circuit board; Mekanik; Vibration; Modal analys; Elektronik utrustning; Kretskort;

    Abstract : This paper presents an investigation of a problem discovered in electronic equipment where mechanical load was the leading cause of the issue. Finite Element Analysis is used to investigate vibration issues in soldering and components. Simulations are performed with ANSYS modal and random vibration package. READ MORE

  5. 4. Multibody modelling of the vibrations in an aircraft engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE

  6. 5. Structural Dynamics at Higher Frequencies using the Finite Element Method : Assessment of Solver Algorithms and Component Mode Synthesis for Dynamic Response Analysis of Large Structures

    University essay from KTH/Hållfasthetslära

    Author : Khashaiar Noushin; [2022]
    Keywords : ;

    Abstract : Scania is making a transition from traditional combustion engines to electric vehicles and therefore developing methodology for high frequency analysis of large structures. The computational time size of results files are impractically high, making any analysis infeasible. READ MORE
