The sophisticated routing control of the bogie

The paper deals with the problems of improving of vehicle characteristics with the new conception of bogies. The goal of research activities is wear reduction of rail wheels and tracks, wear reduction of traction energy losses and increasing of running comfort. For this purpose the experimental rail vehicle with special construction including control algorithms for routing optimization of bogie powered by traction battery is utilized. This vehicle has a rotary bogie with independent rotating wheels driven by permanent magnets synchronous motors and a solid axle. The designed testing control is implemented to the superset control system of this experimental rail vehicle. The traction requirements and curve track radius have an effect to the control. The wheel forces in bogie are measured by large number of the tensiometric sensors and other various vehicle sensors for evaluation of testing control effect. This control including sophisticated routing is verified and corrected according to individual traction and driving characteristics.
