Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced TB/T 2489-1994 Ground Test Method for Horizontal and Vertical Force
of Wheel-track. Compared with TB/T 2489-1994, this Standard made the major technical
changes as follows besides the editorial modifications:
--- Delete the relevant content of patching, bridge assembly and calibration for testing lateral
wheel-rail force using the double-bridge road method (see Clause 3 of the 1994 Edition);
--- Add the relevant content of patching, bridge assembly and calibration for testing lateral
wheel-rail force by shear stress method (see Clauses 4, 5, 6, and 7 of this Edition);
--- Optimize the bridge assembly for testing the lateral and vertical wheel-rail forces by
shear stress method (see 4.3, 5.3 of this Edition; 3.3 of the 1994 edition).
This Standard was proposed by and under the jurisdiction of China Academy of Railway
Sciences – Standard and Metrology Research Institution.
Drafting organization of this Standard: China Academy of Railway Sciences – Railway
Engineering Research Institute.
Chief drafting staffs of this Standard: Hao Yousheng, Tu Yinghui, Li Wei, Chen Songlin, Xu
Liangshan, and Qie Luchao.
The historical edition replaced by this Standard is as follows: TB/T 2489-1994.
Track Side Test Methods of Vertical and Lateral Wheel-Rail
Forces
1 Scope
This Standard specifies the track side test methods of vertical and lateral wheel-rail forces by
shear stress method.
This Standard is applicable to use strain gauges on the rails at the railway site to test the lateral
and vertical wheel-rail forces.
2 Terms and Definitions
For the purposes of this Document, the following terms and definitions apply.
2.1 Lateral force of wheels/rails
The force that is exerted by the wheels on the rail laterally and vertically to the symmetry axis
of the rail section.
2.2 Vertical force of wheels/rails
The force that is exerted by the wheels on the rail in a direction parallel to the symmetry axis
of the rail section.
3 Testing Instruments and Tools
3.1 Instruments
Signal modulator, data acquisition analyzer, etc.
3.2 Tools
500 V or 1000 V insulation meter, lateral force calibration device, vertical force calibration
device and other necessary tools.
4 Method for Testing Vertical Wheel-Rail Force
4.1 Test method
