  1. 1. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Björn Kleman; Henrik Lindgren; [2021]
    Nyckelord :model-based; fault diagnosis; neural networks; data-driven; Hybrid; SCR; exhaust gas treatment system; recurrent neural networks; grey-box; heavy duty truck; fault isolation; fault detection; diagnosis; urea; machine learning; Scania; structural model; MSO; residual; Fault Diagnosis Toolbox;

    Sammanfattning : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. LÄS MER

  3. 2. Injector diagnosis based on engine angular velocity pulse pattern recognition

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :David Nyman; [2020]
    Nyckelord :machine learning; supervised machine learning; neural network; internal combustion engine; fault diagnosis;

    Sammanfattning : In a modern diesel engine, a fuel injector is a vital component. The injectors control the fuel dosing into the combustion chambers. The accuracy in the fuel dosing is very important as inaccuracies have negative effects on engine out emissions and the controllability. LÄS MER

  4. 3. Bearing Diagnosis Using Fault Signal Enhancing Teqniques and Data-driven Classification

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Benjamin Lembke; [2019]
    Nyckelord :Bearing diagnosis; rolling element bearings; predictive maintenance; signal processing; fault detection; gearbox diagnosis; support vector machine; svm; binary classification; one class classification; machine learning; feldetektion; diagnos; feldiagnos; växellåda; signalbehandling; maskininlärning;

    Sammanfattning : Rolling element bearings are a vital part in many rotating machinery, including vehicles. A defective bearing can be a symptom of other problems in the machinery and is due to a high failure rate. Early detection of bearing defects can therefore help to prevent malfunction which ultimately could lead to a total collapse. LÄS MER

  5. 4. Bayesian belief networks for guidedremote diagnostics and troubleshootingof heavy vehicles

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :MAHBUB HUSSAIN KAMALY; [2017]
    Nyckelord :;

    Sammanfattning : Kostnadreducering och eektivisering av reparationer (t.ex i bilindustrin) har varit malet for forskningen kring guidad diagnostik i snart tvadecennier [ 1], med en onskan till intuitiv felsokning och reparation utan tidigare expert kunskaper. LÄS MER

  7. 5. Evaluating An Interactive Troubleshooting System for Heavy Vehicles with Limited Historical Data

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Khair Ghazie; [2017]
    Nyckelord :;

    Sammanfattning : Today’s trucks are built to be modular in order to fit the customer’s specific needs.This means that no two vehicles are  alike, and that makes it difficult to create universal models for diagnosis. LÄS MER
