1. Investigation of torsion modes in overhead traveling cranes: : Reviewing the ISO 22980 standard
Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)Sammanfattning : 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. LÄS MER
2. Vibration analysis and testing of a 6U cubesat propulsion system
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Space industry has been booming in the recent times, investments have not justbeen made on satellites and launch vehicles but also on space sustainability. Spaceindustry has its users in national agencies, private commercial agencies, academia andexperimental organisations. LÄS MER
3. NVH analysis and optimization of electric powertrain
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. LÄS MER
4. Comparative Study of Vision Camera-based Vibration Analysis with the Laser Vibrometer Method
Master-uppsats, KTH/Industriell produktionSammanfattning : Vibration analysis is a method that studies patterns in vibration data and measures vibration levels. It is usually performed on time waveforms of the vibration signal directly and on thefrequency spectrum derived by applying the Fourier Transform on the time waveform. LÄS MER
5. Relating Process Data to Product Quality in Transmission Manufacturing
Master-uppsats, KTH/Industriell produktionSammanfattning : Research has shown that vibration produced by a machine tool provides useful information for the maintenance of its structural parts. Thus, the vibration signal should also give information about tool wear and, consequently, surface roughness of the machined workpieces. LÄS MER
