| description | FIELD: railway transport; rail vehicle control systems. ^ SUBSTANCE: proposed method is based on calculated of peripheral speed and acceleration of all wheelsets, measuring linear acceleration in direction of vehicle movement, setting of driving conditions and calculation of vehicle speed at acceleration and braking. Proposed device contains four wheelset speed transducers whose outputs are connected with corresponding inputs of four differentiators, longitudinal linear acceleration transducer, unit generating vehicle motion signal and unit determining maximum and minimum speeds of wheelsets. Inputs of units determining maximum and minimum speeds of wheelsets are coupled with outputs of wheelset speed transducers. Device contains two compensating linear acceleration transducers, speed calculating and vehicle acceleration calculating units, two units generating corrections for calculation of acceleration of vehicles. ^ EFFECT: provision of efficiency of acceleration and braking process in wide range of change of adhesion coefficient owing to more accurate accounting of slipping or wedging of wheel and also protection of wheel roll surfaces from slides and well pads. ^ 5 cl, 1 dwg |
