ON REAL-TIME SIMULATION OF THE LONGITUDINAL DYNAMICS OF TRAINS ON A SPECIFIED RAILWAY LINE

Abstract

The dynamical model of the train is a simplified linear lumped-parameter one. The steady-state tractive effort is specified by the points of the bivariate, control and velocity dependent tractive effort performance curves. The train is equipped with an airbrake sys- tem. The vehicles in the train are characterized by the traction resistance functions, while the railway line is specified by the arclength-dependent track-slope and track-curvature functions. The equations of motion of the train are numerically solved under real-time conditions. The drive and brake controls are given from the computer keyboard. The results of the real-time simulation can be continuously followed on the computer screen. Statistical analysis of the results and visualization can also be initiated through activizing evaluation software.
