Tkachenko V. Account and forecasting of railway vehicle travelling frictional resistance to а movement

The dissertation is directed on reduction of expenses powers on train traction. A complex of researches of travelling frictional resistance to a movement of railway vehicle, caused kinematics and dynamics friction interaction of wheel pairs and way is carried out. In work develop rules of the theory of closed force contours with reference to kinematics circuits of a direction of wheelset by a railway develop. A technique of account and forecasting travelling frictional resistance to a movement is offered and its characteristics for the majority of types of the serial rolling-stock are received. The experimental characteristics of coupling and kinematics resistance to a movement in "wheel-rail" system are received at point-to-point contact. Concept is entered and criteria cross operate of rail crews are formulated. Principles of designing of railway vehicles with lowered resistance to a movement are determined.
