Operational stability is evaluated, by the use of index, such as derailment coefficient, wheel load reduction rate, wheelset lateral force, lateral stability. 9.1.2 Derailment coefficient
9.1.2.1 The derailment coefficient is used to evaluate, whether the wheel rim of the vehicle will climb up the rail head and derail, under the action of lateral force. 9.1.2.2 The derailment coefficient is the ratio of the lateral force Q, which is applied to the rail by the wheels on the rail-climbing side, to the vertical force P, which is applied to the rail, that is, the derailment coefficient is Q/P. 9.1.3 Wheel load reduction rate
9.1.3.1 Wheel load reduction rate is another derailment safety index, for evaluating derailment, which is caused by excessive reduction of wheel load. 9.1.3.2 The wheel load reduction rate is the ratio, of the wheel load reduction ??P to the average static wheel weight of the axle, that is, the wheel load reduction rate is ??P/ .

Measurement of wheel-rail interaction force
C.1 Overview
The wheel-rail interaction force is measured by a force-measuring wheelset. The force-measuring wheelset is a special sensor, for measuring wheel-rail interaction force. Usually, strain gauges are arranged on the wheel web of the force-measuring wheelset, to form a measuring bridge.
C.2 Factors to be considered in the design of the force-measuring
wheelset
The following factors shall be considered when designing the force measuring wheelset:
a) The indexing lines of the left and right wheel bridges shall be coincident; b) The output of the vertical force bridge and the lateral force bridge, shall have higher sensitivity and lower influence coefficient;
c) It shall eliminate the mutual influence of vertical force and lateral force output;
d) Effectively eliminate the influence of the position of the wheel-rail action point;
e) Effectively eliminate the influence of thermal stress;
f) Effectively eliminate the influence of centrifugal inertia force.
C.3 Calibration of force-measuring wheelset
C.3.1 The force-measuring wheelset shall be calibrated on a dedicated
calibration test bench.
C.3.2 The vertical force and lateral force are respectively loaded, step by step. The vertical calibrated load shall not be less than 1.5 times the weight of the static wheel. The lateral calibrated load shall not be less than 1.2 times the weight of the static wheel. At the same time, record the output of the loading force AND the force-measuring wheelset's bridge path.
C.3.3 After the calibration of the force-measuring wheelset, calculate the proportional coefficients Kpp and Kqq of the vertical force and the lateral force, Appendix D

D.2.1.1 Processing of assessment values, such as derailment coefficient, wheel load reduction rate, wheelset lateral force
Calculate all valid sampling data on the sampling segment; THEN, perform 2 m sliding average processing.
For each sampling segment, take the 99.85% value, which is corresponding to the cumulative frequency curve of the absolute value of the sampling data, as the sample xi of each sampling segment.
D.2.1.2 Processing of operational quality assessment values ??ty and ??tz The operational quality assessment values, ??ty and ??tz, are calculated and processed as follows:
a) For rolling stocks, passenger trains, EMUs, use 0.4 Hz ~ 40 Hz for band- pass filtering. For freight trains, use 0.4 Hz ~ 15 Hz for band-pass filtering. b) Calculate the absolute value of the maximum value ximax and minimum
value ximin of acceleration, in the sampling segment. Each value serves as a statistical sample.
