The reasons of spontaneous operation of autobrakes in freight trains

Traffic safety of trains is a priority task of JSC «Russian Railways». In article the reasons of spontaneous operation of brakes of freight trains are investigated and their statistics depending on density of brake network of the train is given. Calculation of pressure in the camera under the equalization piston of the crane of the driver is made. Inertial characteristics of the equalization piston and its static characteristics are defined. Process of spontaneous operation of autobrakes on the basis of fundamental laws of a hydraulic gas dynamics is simulated.
