  1. 1. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Rui Zhou; [2023]
    Keywords : ;

    Abstract : This research aims to investigate accurate classification of anomalous vibrations produced during vehicle operation. The main research questions are which data can be used as classification criteria, which models can better achieve classification effects, and how to address classification issues under different variables in a car.

  3. 2. Study and optimization of a hexacopter's composite structure

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Helena Delmotte; [2023]
    Keywords : Lightweight structure; Drone; Structural optimization; FEA; Lättviktsstruktur; Drönare; Strukturell optimering; FEA;

    Abstract : Nowadays, the forestry industry still uses heavy machinery damaging both the forest and the soil. The start-up AirForestry is currently developing a sustainable way to thin and harvest trees. With their 6.2m wide electric drone carrying a harvesting tool, they can reach, thin, cut and carry trees without the need for access roads. READ MORE

  4. 3. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhiyanesh Radhakrishnan; [2021]
    Keywords : Electro-Magnetics; Eigenfrequency; Electrical Machine; Multi-Body Dynamics; Displacement; machine vibrations; Elektromagnetik; Eigen frekvens; Elektrisk maskin; Flerkropps dynamik; Förskjutning; maskin vibrationer;

    Abstract : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. READ MORE

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

    University essay from Linköpings universitet/Fordonssystem

    Author : Benjamin Lembke; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Robot Condition Monitoring and Production Simulation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Martin Karlsson; Fredrik Hörnqvist; [2018]
    Keywords : Robot Condition Monitoring Production Simulation SKF ABB IRB 6600 Vibration;

    Abstract : The automated industry is in a growing phase and the human tasks is increasingly replaced by robots and other automation solutions. The increasing industry entails that the automations must be reliable and condition monitoring plays an important role in achieving that ambition. READ MORE
