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 tf to define deviation of actual temperature öt"Çà". New temperature of assembled rails and tracks fixture in the curve by the following formula: t".Çà"=t3-öt"Çà", where tf is temperature of assembled rails and tracks fixture, C. Then, stability of circular curve defined by the formula: t".Çà">mintf and determined crosswise stability margin within the limits of circular curve (ööt"Çà") defined by the formula: ööt"Çà"=t".Çà"-mintf, are used to decide on state of assembled rails and tracks. ^ EFFECT: higher accuracy. ^ 2 tbl, 2 dwgl |
