Open Rails

Axle.SlipCharacteristics Method

[This is preliminary documentation and subject to change.]

Slip characteristics computation - Computes adhesion limit using Curtius-Kniffler formula: 7.5 umax = --------------------- + 0.161 speed * 3.6 + 44.0 - Computes slip speed - Computes relative adhesion force as a result of slip characteristics: 2*K*umax^2*dV u = --------------------- umax^2*dv^2 + K^2

public float SlipCharacteristics(
   float slipSpeed,
   float speed,
   float K,
   float conditions,
   float Adhesion2
);

Parameters

slipSpeed
Difference between train speed and wheel speed MpS
speed
Current speed MpS
K
Slip speed correction. If is set K = 0 then K = 0.7 is used
conditions
Relative weather conditions, usually from 0.2 to 1.0
Adhesion2

Return Value

Relative force transmitted to the rail
