Abstract: Todays, urban transportation began to get more importance because of increasing rates of urbanization and the traffic problems. Therefore, railway systems have started to play a key role in urban transportation with technological development because of rapid transit, less carbon emission, low ratio between the energy consumption and transport capacity. In this study, the grid and DC traction power supply system of a subway which is the widespread urban electrical railway systems has been modeled by using MatLAB Simulink. Electrical analysis was carried out of the subway line according to the variable load and different line distance.

Abstract: The present study proposed an electromagnetic shock-absorber (EMSA) consisting of a copper and steel combined tube, a piston, permanent magnets, and a steel ring. A magnet fixed on the piston moves through the tube when driven by an external shock. This shock energy is partially dissipated by an eddy current damping force and a friction force generated from the relative motion of the magnet and the tube. A part of the energy is stored in a magnetic spring consisting of two magnets. To predict the performance of the proposed EMSA these damping and magnetic forces are simulated and approximated by using an electromagnetic finite element program. The present simulation results are verified by the experimental results.
