METHOD OF DEFINING STATE OF CONTINUOUS WELDED RAIL TRACK ASSEMBLED RAILS AND SLEEPERS Russian patent published in 2012 - IPC B61K9/08 E01B35/00 

FIELD: transport.

SUBSTANCE: invention relates to continuous control over continuous welded rail track by track measuring devices. Proposed method comprises defining averaged curvature in the limits of circular curve on basic length defined by regulations and defining averaged curvature on preset length of short irregularity. For every circular curve, defined is designed minimum temperature of fixture min t_f to define deviation of actual temperature Δt_"рих". New temperature of assembled rails and tracks fixture in the curve by the following formula: t_"о.рих"=t₃-Δt_"рих", where t_f is temperature of assembled rails and tracks fixture, °C. Then, stability of circular curve defined by the formula: t_"о.рих">mint_f and determined crosswise stability margin within the limits of circular curve (ΔΔt_"рих") defined by the formula: ΔΔt_"рих"=t_"о.рих"-mint_f, are used to decide on state of assembled rails and tracks.

EFFECT: higher accuracy.
