Book Description
This Part specifies the indoor test methods for clamping force of fastener. This Part is applicable to the fastening systems of high-speed railway. 2 Sign The following signs are applicable to this Document. d: the vertical displacement of the sleeper relative to the rail, in millimeters (mm); ms: the mass of the sleeper or part of the sleeper used for testing and the fastening components assembled thereon, in kilograms (kg); mf: the mass of the reinforcement frame supported by the sleeper, in kilograms (kg); P: vertical force acting on the rail or sleeper, in kilonewtons (kN); P0: Just offset the clamping force, the vertical force when the rail has zero displacement, in kilonewtons (kN); P1: The vertical force acting on the rail or sleeper when the average reading of the displacement sensor is zero, in kilonewtons (kN). 3 Principles The clamping force of the fastener is determined by measuring the force that disengages the rail from the rail bearing surface. 4 Test Equipment 4.1 Rail TB/T 3396.2-2015 www.ChineseStandard.net ? Buy True-PDF ? Auto-delivery. Page 5 of 9 A section of short rail with a length of about 0.5m, whose cross-section is the same as that used for the assembly of the fastener to be tested or for the fatigue performance test of the assembly. There shall be no peeling off the rails, and no floating rust on the surface. 4.2 Loading device The device with loading rate of 9kN/min ~ 11kN/min, static loading up to 50kN for applying vertical loads. For the reference test method, the load is applied to the rail; for the alternative test method, the load is applied to the reinforcement frame supported on the sleeper on the shelf. 4.3 Displacement sensor An instrument for measuring the vertical displacement of the rail relative to the sleeper, with an indication error of 0.01 mm. 4.4 Load cells An instrument for measuring the load applied to the rail or to the reinforcement frame supporting the sleeper, with an accuracy class of 0.5. 4.5 Recording device T...

Book Description
This Part specifies the indoor test method for the longitudinal resistance of rails assembled with fasteners. This Part applies to fastening systems for high-speed railways. 2 Sign The following signs are applicable to this Document. D1: The maximum longitudinal displacement of the rail during the loading cycle, in millimeters (mm). D2: The residual longitudinal displacement of the rail after unloading, in millimeters (mm). D3: Elastic longitudinal displacement of the rail before sliding, in millimeters (mm). F: The longitudinal resistance of the rail, in kilonewtons (kN). 3 Principle Assemble the short rail with fasteners on the rail bearing surface of the anchored sleeper; and apply longitudinal tension to the rail; record the load and the longitudinal displacement of the rail relative to the sleeper; and unload when the rail slips. The longitudinal resistance of the rail is obtained from the load-displacement curve. 4 Test Equipment 4.1 Rails A section of short rail with a length of about 0.5 m, whose section is the same as that used for the assembly of the fastener to be tested or the assembly fatigue performance test. The rails shall be free from peeling, free from floating rust on the surface; and the bottom of the rails TB/T 3396.1-2015 www.ChineseStandard.net ? Buy True-PDF ? Auto-delivery. Page 5 of 9 shall not be polished due to repeated tests. 4.2 Loading device The device with the loading rate of 9kN/min ~ 11kN/min, and the static loading can reach 50kN, which applies the tension in the direction of the vertical sleeper through the bottom of the rail. 4.3 Displacement sensor An instrument for measuring the longitudinal displacement of the rail relative to the sleeper, with an indication error of 0.01 mm. 4.4 Load sensor An instrument for measuring the load applied to the rail, with an accuracy class of 0.5 4.5 Recording equipment For equipment capable of digitally recording and drawing load-displacement curves during the test, the sampling frequency shal...

Book Description
This Part specifies the indoor test method for the static stiffness of fastening assemblies. This Part applies to high-speed railway fastener systems. 2 Symbols The following symbols apply to this document. F1: The minimum load applied to the tested fastener system, in kilonewtons (kN); F2: The maximum load applied to the tested fastener system, in kilonewtons (kN); D1: The displacement of the rail when loaded to F1, in millimeters (mm); D2: The displacement of the rail when loaded to F2, in millimeters (mm); KSTA: Assembly static stiffness, in kilonewtons per millimeter (kN/mm). 3 Principles Apply a load, which is perpendicular to the bottom surface of the rail, to the rail (assembled on a single bearing surface) with the fastener system assembled by the testing machine, to determine the displacement of the rail, as relative to the sleeper, under the load. 4 Test equipment 4.1 Steel rail A segment of short steel rail, which has a length of about 0.5 m, the section of which is the same as the section of the steel rail used for the tested fastening assembly or assembly fatigue performance test. The steel rail shall be free of peeling and rust on the surface. TB/T 3396.3-2015 www.ChineseStandard.net Buy True-PDF Auto-delivery. Page 5 of 6 4.2 Loading device A device, which has a loading rate of 2 kN/s ~ 6 kN/s, a static loading reaching up to 110 kN, is used to apply vertical load to the rail surface. 4.3 Displacement sensor The instrument for measuring the vertical displacement of the rail, as relative to the sleeper, which has an indication error of 0.01 mm. 4.4 Load sensor An instrument for measuring the load, which is applied to the rail; it has an accuracy grade of 0.5. 4.5 Recording device A device, that can perform digital recording and draw a load-displacement curve, during the test. It has a sampling frequency of not less than 50 Hz. 5 Test pieces 5.1 Sleeper Sleepers, 1/2 sleepers or slab track units with embedded fasteners or reserved bolt holes (all d...
