摘要
By analyzing causes, damages and popular solutions for gnawing rail phenomenon of Rail-Mounted Gantry （shorted for RMG）, this article puts forward a kind of automatic correcting control system, the system can change between two transducer connection forms, and as a result, can prevent or decrease gnawing rail problem to a great extent. We present principles of correcting obliquity, sideward displacement of gantry frame and principles of malfunction diagnosis and some important schematic diagrams. The most significant feature of our system is that we can change transducers＇ connection form to respective or cross driving mode according to the extent of obliquity and sideward displacement of gantry frame, which make full use of both modes＇ advantages. As a result, the system not only can minish gnawing rail phenomenon, diagnose causes of gnawing rail and give an corresponding alarm, but also, in cross connection driving mode, has an unique capacity of preventing gnawing rail phenomenon utilizing its own characteristics under cross connection mode and gantry frame＇s rigidity.
