MEASUREMENT OF THE MAGNITUDE AND ECCENTRICTY OF TIE PLATE LOADS

Measurement is made of the magnitude and eccentricity of tie plate loads. A dynamometer tie plate is developed with which the tie plate loads and eccentricity of loading can be accurately determined. Topics discussed include description of the dynamometer tie plates, discussion of test procedure and data, analysis of a 4-degree test curve, tangent track, applied vertical wheel loads and position of the centroid of pressure, and vertical stresses in lower rail fillets measured over the dynamometer tie plates. It is noted that the measurement of magnitude and eccentricity of the tie plate loads would be simplified if it were possible to determine these properties from rail stress measurements above conventional tie plates which could be left undisturbed in the track.
