Traction asynchronous electric drive of mine electric locomotivesimulation model structure improvement

The article discusses the solution to problem of underground railway transport slipping in dynamic modes, which occurs when there is a significant difference speeds driving and driven pairs wheels. state rail surfaces largely determines coefficient adhesion, therefore, using mathematical model, condition for dependence magnitude tractive effort selected. For effective acceleration deceleration an electric locomotive, it necessary control adhesion at certain level. A simulation model rolling stock has been created, first time takes into account mechanical system with distributed parameters. In structural diagram automatic traction drives frequency regulation, such factors as volume goods being moved, friction, slope (rise) levels track are taken account. results show features movement stops freight train not only by diagrams speed forces modes acceleration-deceleration uniform movement, but also positions plungers on couplings locomotive all trolleys involved goods. practical application proposed method lies possibility starting heavily laden from its place ascent section conditions insufficient contaminated roads.
