  1. 1. Formula Student Car Stability

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Oliver Belfiore; [2023]
    Keywords : Racing; Car; Vehicle; dynamics; vehicle dynamics; Technology and Engineering;

    Abstract : This thesis investigates the impact of varying passive components on the stability of a Formula Student race car. The study was conducted using a 7-post model and a lateral model, both of which were derived using Lagrangian methods and state-space modelling techniques. These models were then validated and adjusted using logged data. READ MORE

  3. 2. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Gustav Blomgren; Ebba Carlsson; [2023]
    Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

  4. 3. Statistical Analysis and Modelling of Engine Oil Degradation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Bastiampillai; [2023]
    Keywords : ;

    Abstract : An engine oil has several important properties it must fulfil in order to provide efficient engine operation. In addition to damping friction by lubrication, an engine oil must be able to cool, protect against corrosion, dampen vibrations and clean surfaces from contamination, wear and residual products.

  5. 4. Model verification and common mode current analysis of grid connected three phase two level converters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Lindvall; Richard Haraldsson; [2021]
    Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE

  6. 5. Role of damping in NVH CAE procedures

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Rahul Sharma; [2021]
    Keywords : NVH; CAE; Damping;

    Abstract :   Automotive manufacturers currently face a challenge with expeditious enhancement of the vibro-acoustic properties of their vehicles. A major reason for this setback is the limited design information available during initial development stages added with limited knowledge of damping within complex structures. READ MORE
