Abstract

The invention provides an active radial control method and system for a train. The control method comprises the following steps: S1, acquiring train running route information and train driving information; S2, calculating and generating an active radial control instruction according to the train running route information and the train running information; and S3, controlling a wheel set to be in a radial position according to the active radial control instruction. The control system comprises a signal acquisition device, an upper computer and a radial execution mechanism. According to the active radial control method for the train, the bogie has the good curve passing capacity, friction between wheel rails is reduced, the service life of the wheel rails is prolonged, whistling generated by wheel rail friction when the train passes through the curve is eliminated, and the radius of the curve where the train passes through is reduced. And the running stability, flexibility and safety of the train are improved.

Description

Technical field[0001]The present invention relates to the field of rail train radial systems, and more particularly to a train motion radial control method and a control system.Background technique[0002]At present, urban rail transit has more small radius curves on the line, and the traditional steering frame for urban rail transit is used by the small radius curve. The wheel rim is tightly relying on the rail, the wheel is high, and there is a severe rotten wear. And produce larger operating noise, reducing the service life of the wheel, which can cause the steering frame to deraille. Therefore, for safety reasons, the vehicle must be running at the time of the corner, which reduces the operational efficiency of the vehicle.[0003]In order to solve such problems, patent CN201151401Y proposes a self-guided device suitable for a passenger car steering holder, and the front and rear wheels of the steering frame are coupled together by a set of linkage mechanisms to cause the wheel to t...
