1. Estimation of Input Forces on a Cutting Tool using Strain Output Signals
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : 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

2. Estimation of blocked forces from a rear drive unit (RDU) in a test rig fixture
University essay from KTH/Teknisk akustikAbstract : In the modern world, vehicle manufacturers are not the sole producer of every component in a vehicle but instead assign different subsystems to various OEMs (Original Equipment Manufacturer). Subsystems such as Rear Drive Units (RDU), Power Transfer Units (PTU), E-drives etc. are developed separately and then integrated into the main vehicle. READ MORE

3. HSI effects on pedestrian bridges
University essay from KTH/Bro- och stålbyggnadAbstract : 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. READ MORE

4. Vibrational prediction of a waste water pump
University essay from KTH/HållfasthetsläraAbstract : An off-market waste water pump is suspected to have high vibrational velocity levels. These vibrations are sought after at the outer surface located at the upper bearing position of the pump. It has then become of interest for trying to predict these vibrations by using the commercial FEA software COMSOL. READ MORE

5. Component-Based Transfer Path Analysis and Hybrid Substructuring at high frequencies : A treatise on error modelling in Transfer Path Analysis
University essay from KTH/Maskinkonstruktion (Avd.)Abstract : The field of modal testing and analysis is currently facing a surge of interest in error modelling. Several errors which occur during testing campaigns are modelled analytically or numerically and propagated to various system coupling and interface reduction routines effectively. READ MORE
