Kijko A. Increase of efficiency of electric locomotive antiskid system

The Thesis deals with raising the efficiency of electric locomotive antiskid systems by means of creating and establishing microprocessor systems of fixing top forces of wheel set-rail cohesion. On the basis of the results of dynamic process mathematical modelling in the system of traction electric drive - wheel set rail track - antiskid system m different maintenance regimes the algorithm of functioning and microprocessor device of fixing lop forces wheel set-rail cohesion have been developed. This microprocessor device ensures prevention of skid process due to the transitory preventive feed of sand under corresponding wheel sets. The process is automatically regulated by microprocessor device by means of analysis of dynamic processes in an electric drive of every wheel set.
