  1. 11. Fault diagnosis of axlebox roller bearings of high speed rail vehicles based on empirical mode decomposition and machine learning

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JOSUA KEHLENBACH; [2021]
    Keywords : Condition monitoring; axlebox bearings; machine learning; data fusion; Nyckelord: tillståndsövervakning; axelboxlager; maskininlärning; datafusion;

    Abstract : Axlebox bearings are one of the most critical components of a rail vehicle with regard to safety. An axlebox bearing that breaks during operation can be dangerous for the passengers and expensive for the operator. In-service failure of axlebox bearings has been the cause of many catastrophic accidents. READ MORE

  3. 12. Sensors for intelligent and reliable components

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Pontus Lundman; [2020]
    Keywords : Wind turbine; Gearbox; Sensor; Condition monitoring; Cyber-physical system; Vindkraftverk; Växellåda; Sensor; Tillståndsövervakning; Cyberfysiskt system;

    Abstract : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.

  4. 13. Early Gear Failure Detection in Fatigue Testing of Driveline Components

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Govindraj Sannellappanavar; [2020]
    Keywords : Autoregressive modelling; Condition monitoring; Gear fault detection; Vibration analysis; Autoreggressiv modell; Feldetektering i växel; Tillståndsövervakning; Vibrationsanalys;

    Abstract : Early failure detection has been an integral part of condition monitoring of critical systems, such as wind turbines and helicopter rotor drivetrains. An unexplored application of early failure detection is fatigue testing of driveline components. READ MORE

  5. 14. Condition monitoring of induction machines using a signal injection technique

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

    Author : Sathiya Lingam Senthil Kumar; [2020]
    Keywords : Condition monitoring; fault detection; fault diagnosis; stator winding fault; inter-turn fault.; Tillståndsövervakning; feldetektering; feldiagnos; statorlindningsfel; kortslutning mellan varv.;

    Abstract : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. READ MORE

  6. 15. Vibration analysis for predictive maintenance of a rotary pump. : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Gustav Osswald; [2019]
    Keywords : ;

    Abstract : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. READ MORE
