How to Calculate Curve Resistance?
Curve Resistance calculator uses Curve Resistance = Tractive Force-Tractive Force*cos(Angle subtended by Radius of Curve for Single Lane) to calculate the Curve Resistance, The Curve Resistance formula is defined as the added resistance or “drag” on a train that must be overcome by the tractive effort in rounding a curve. Resistance is usually measured in newtons per ton of train weight. Curve Resistance is denoted by CR symbol.
How to calculate Curve Resistance using this online calculator? To use this online calculator for Curve Resistance, enter Tractive Force (T) & Angle subtended by Radius of Curve for Single Lane (α_{1}) and hit the calculate button. Here is how the Curve Resistance calculation can be explained with given input values -> 517997.6 = 0.2-0.2*cos(1.5707963267946).
