SUBSTANCE: invention relates to methods of checking and forecasting condition of rail track. According to proposed method, running course of body of track-testing car is measured by means of inertia navigational system installed under pivot of test bogie, and running hunting angle of test bogie relative to body is measured by means of angular displacement transducer. Then, using axle box-rail transducers, distance from flanges of corresponding wheels of bogie to rail heads are measured. Basing on obtained information , running courses of rail lines are calculated as running course of body minus running hunting angle of test bogie relative to body minus running angle of parallel misalignment of flanges of wheelsets of test bogie and heads of rail lines. Then running values of horizontal irregularities of rail lines are found as product of bogie base by deflection of running course of rail lines from running averaged courses of rail lines on bogie base calculated from courses of rail lines. Running radii of curvature of rail lines are found by dividing bogie base by measured increment of course angles of rail lines on bogie base.
EFFECT: provision of chordless (single point) method of checking leveling of rail lines.
FIELD: railway transport; testing.
SUBSTANCE: according to proposed method of measuring vertical rigidities of rail lines by track testing car forces are measured by which track testing car acts on wheels when wheel-sets pass each fixed point. At initially different static loads on axle, vertical irregularities of rail lines are measured by means of two wheel-sets using cordless method. Values of vertical rigidities of rail lines are found as ratio of difference of forces acting onto corresponding (left-hand or right-hand) rail line to difference of vertical irregularities of corresponding rail line in fixed point. Mean rigidity of rail track in each fixed point is determined as mean arithmetic value of vertical rigidities of each rail line.
EFFECT: improved accuracy of measurement of rigidity of rail lines.
FIELD: railway transport; testing.
SUBSTANCE: according to proposed method, frame forces acting onto each wheel-set are measured at passing of each fixed point of rail track by all wheel-sets. Simultaneously side (cross) irregularities of rail lines are measured by cordless methods and basing of received information, six independent equations are set up where 1, j = 1,2,3,4, are wheel-sets; and are side rigidities of left-hand and right-hand rail line in k-th fixed point on rail track; and where and are irregularities of left-hand and right-hand rail lines measured at passing of k-th fixed point by i-th wheel-set; where is frame force acting onto i-th wheel-set at passing k-th fixed point of track. Then system is chosen from six equations consisting of two equations so that system should be nonuniform and definite (determinant and values of rigidities and are found by Cramer formula.
EFFECT: possibility of measuring side rigidity of rail lines by track testing car.
FIELD: railway transport; testing facilities.
SUBSTANCE: invention can be used for checking wear of rails on railways and streetcar tracks. Device for testing wear of rails includes pulse generator and recorder and second pulse generator. First and second pulse generators are made in form of electronic transducers furnished with spring-loaded rods with rack gears engaging with surfaces of rail and with gears on axles of which light breakers are installed, and with light emitting diodes connected by wires with photorelays. Recorder is made up of radio electronic elements, supply unit and control panel with push buttons and change-over switches. Pulse generators and recorder are connected by wires. First pulse generator is installed on base on edges of which bellcranks are mounted for rotation on joints. Position lock of bellcranks is installed between upper parts of bellcranks furnished with handles, position lock being made of concave parts and screw. Second pulse generator is installed lower than the base on one of bellcranks. Stops with slots and fastening screws are made in lower parts of bellcrank to secured their position relative to bellcranks.
EFFECT: improved safety, reduced possibility of breakdown in operation of rolling stock on railways and streetcar tracks.
