The paper is concerned with an analysis of behaviour of the cableway. On the basis of design data and results of adequate experiments, a physical model of cableway was formulated. The static of cableway was developed assuming a full nonlinear model based on elastic catenary curve. The tension of the rope and the reactive forces between the rope and the supports were calculated. Assuming various loadings of the rope, the relation between the tension in bottom and upper stations and the length of the rope was determined. The model describing the motion of the system is linear. Finite elements were used to formulate the model. Two methods of accelerating the system were investigated.

Short-term contact losses between a pantograph and a contact wire are not included in the standards nor are they taken into account in evaluating pantograph-contact wire interaction. These contact losses, however, accelerate wear and tear as well as disturb operation of vehicles’ drive systems. The article presents the effects of short-term contact breaks as well as an analysis of impact of contact breakages on a vehicle’s current at 3 kV DC power supply. Results of voltage and current oscillations measured in real conditions when pantograph of a DC driven chopper vehicle was running under isolators were presented. Then a simulation model of a vehicles with ac motors and voltage inverters was derived to undertake simulation experiments verifying operation of such a vehicle in condition similar to those measured in real condition.

The study presents a calculation method of the voltage induced by power-line sagged conductor in an inductively coupled overhead circuit of arbitrary configuration isolated from ground. The method bases on the solution utilizing the magnetic vector potential for modeling 3D magnetic fields produced by sagging conductors of catenary electric power lines. It is assumed that the equation of the catenary exactly describes the line sag and the influence of currents induced in the earth on the distribution of power line magnetic field is neglected. The method derived is illustrated by exemplary calculations and the results obtained are partially compared with results computed by optional approach.

To effectively suppress the violent galloping of the catenary additional wires in the strong wind section of high-speed railways, the anti-galloping effectiveness and anti-galloping mechanism of the spacer installed on the catenary additional wires are studied. Firstly, the finite element model of the additional wires of the catenary before and after the installation of the spacer is established. Secondly, the random wind field at the additional wires is simulated by the harmonic synthesis method (WAWS). Finally, the galloping response of the additional wires before and after the installation of the spacer is studied by using the finite element software. The results show that the installation of a single spacer at the midpoint of the span can reduce the vertical amplitude of the AF (Additional Feeder) and the PW (Protection Wire) by more than 39.80% and 41.51%, respectively, and the lateral amplitude decreases by more than 16.55% and 38.30%, respectively. The tension of the AF is greatly reduced, while the tension of the PW is slightly increased, so that the galloping of the AF and the PW tends to be synchronized. With the increase in the number of spacers installed, the anti-galloping effect continues to increase. At the same time, the anti-galloping mechanism of the spacer rod to suppress the vibration of the additional wires through the traction effect is clarified, and the effectiveness of the spacer rod in the anti-galloping of the additional wires of the catenary is proved.
