1. 1. 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

3. 2. Estimation of Input Forces on a Cutting Tool using Strain Output Signals

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Ram Pradip Mahato; Jiacheng Ma; [2022]
   Keywords : Lathe tool; Multiple sensor signals; Modal analysis; Input force calculation; embedded sensor force; MATLAB;

   Abstract : Lathes are frequently used in industrial production. It is an important parameter to calculate the force exerted by the cutter head on the raw material. Knowing the force acting on the cutting tool will aid in predicting the displacement of the cutting edge as well as predict displacement of the workpiece. READ MORE

4. 3. Driving forces of spatial cognition : Is the car a mover in egocentric distance estimation?

   University essay from Uppsala universitet/Kulturgeografiska institutionen

   Author : Martin Horn; [2022]
   Keywords : distance cognition; modal choice; action-specific perception; car driving; urban planning;

   Abstract : Physical inactivity is a cause of health problems globally that cause suffering for people and amass significant costs for states. One way of improving physical activity is by formulating policy and implementing planning decisions that encourage active travel. At the heart of the issue, however, lies the matter of modal choice.

5. 4. Modelling and testing of a solar panel structure for KNATTE (Kinesthetic Node and Autonomous Table-Top Emulator)

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Elena Fernández Bravo; [2021]
   Keywords : Frictionless platform; Linear Quadratic Gaussian; Flexible appendages; Finite Element Method;

   Abstract : One of the challenges that satellites face is the interaction between control movement and vibration of flexible appendages such as solar arrays and antennas that can negatively affect the performance of the spacecraft. The aim of this thesis is to develop a numerical model of a solar panel structure for KNATTE, a frictionless platform developed by the Onboard Space Systems group at Luleå University of Technology, and develop a control law that reduces the flexible vibration of the solar arrays when attitude control manoeuvres are performed.

6. 5. Dynamic Analysis of Portal Frame Railway Bridges - Case Studies Investigating the Structural Response

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

   Author : Benjamin Berg; Pontus Nyberg; [2020]
   Keywords : Dynamic Analysis; Portal Frame Bridges; High Speed Trains; Railway Bridges; Finite Element; Resonance; Modal Analysis; BRIGADE Plus; Technology and Engineering;

   Abstract : As the world continues to see an increase in carbon dioxide emissions, actions aiming towards reducing man's negative impact on the environment are paramount. To be able to compete with the air travel industry, the Swedish Transport Administration suggests a vast expansion of the existing railway system. READ MORE
