  • Modal analysis of railway current collectors using Autodesk Inventor
    Publication

    - Year 2018

    The paper presents the results of modal analysis of railway current collector type 160EC. In the first place, the analysis was carried out analytically for a simplified two lumped mass pantograph model. Then numerical analysis was conducted in the Autodesk Inventor (AI) on the prepared multibody model using the AI modal analysis algorithm, which is based on the finite element method (FEM). Model elements which are most relevant...

  • Monitoring of current collectors on the railway line
    Publication

    Proper cooperation the current collectors and the overhead line is a pre-requisite for reliable and safe operation of railway transport. Instances of maladjustment and, in some cases, damage to the current collectors, occur between periodic inspections of the rolling stock. In order to detect such anomalies quickly, the test stand was developed, with the aim of monitoring the technical state of the current collectors under operating...

  • Novel analysis methods of dynamic properties for vehicle pantographs
    Publication

    - Year 2018

    Transmission of electrical energy from a catenary system to traction units must be safe and reliable especially for high speed trains. Modern pantographs have to meet these requirements. Pantographs are subjected to several forces acting on their structural elements. These forces come from pantograph drive, inertia forces, aerodynamic effects, vibration of traction units etc. Modern approach to static and dynamic analysis should...

  • Potential Application of Solar Energy Systems for Electrified Urban Transportation Systems
    Publication

    The paper presents a novel approach toward the use of solar energy systems in public transportation. The concept of energy generation in PV systems for supplying a trolleybus transportation system is proposed for the city of Gdynia (Poland). The suggested way of energy production allows reducing the environmental harm impact of the municipal transportation system. Moreover, the proposed way of green energy use can be a more profitable...

  • SMART GRID TECHNOLOGIES IN ELECTRIC POWER SUPPLY SYSTEMS OF PUBLIC TRANSPORT
    Publication

    Nowadays the issue of electric energy saving in public transport is becoming a key area of interest which is connected both with a growth in environmental awareness of the society and an increase in the prices of fuel and electricity. It can be achieved by improving the usage of regenerative breaking. In 2016 the Przedsiębiorstwo Komunikacji Trolejbusowej (PKT, Trolleybus Transport Company) in Gdynia began practical implementation...

  • The issue of uncertainty of visual measurement techniques for long distance measurements based on the example of applying electric traction elements in diagnostics and monitoring
    Publication

    - MEASUREMENT - Year 2018

    Rail transport is the most economical and energy-effective in the field of land transport, in particular electrified. In order to ensure efficient and reliable operation of electrified rail transport, the issues of monitoring and diagnostics of the traction infrastructure and vehicles are extremely important. The most critical point in the transmission of electric energy to the vehicle is the sliding contact of the current collector...

  • Visual method for detecting critical damage in railway contact strips

    Ensuring an uninterrupted supply of power in the electric traction is vital for the safety of this important transport system. For this purpose, monitoring and diagnostics of the technical condition of the vehicle's power supply elements are becoming increasingly common. This paper presents a new visual method for detecting contact strip damage, based on measurement and analysis of the movement of the overhead contact line (OCL)...

  • Wizyjne metody pomiarowe w diagnostyce górnej sieci trakcyjnej
    Publication

    - Year 2018

    Monografia zawiera analizę wykorzystania – na potrzeby diagnostyki i monitoringu górnej sieci trakcyjnej – wizyjnych metod pomiarowych, a w szczególności metody autorskiej opartej na użyciu kamery obrazowej i analizie obrazu, pozwalających na pomiar położenia obiektu fizycznego w przestrzeni dwuwymiarowej. Opracowana metoda łączy wysoką funkcjonalność, dużą rozdzielczość pomiarową oraz bardzo niski poziom niepewności pomiaru z...
