Different types of Train Resistance
Resistance due to Internal Parts(Rt1) is the resistance between cylinder and rim of driving wheels, resistance of other moving parts and resistance of locomotive and wagons and it is given by 0.0016w.
Resistance due to Flange Friction, Osciliations, Swaying, etc. (Rt2) is because the locomotive moves in a zig-zag manner within the limits of wheel gauge tolerence called 'Nosing Action' and it is given as 0.00008wv.
Atmospheric Resistance(Rt3) is the resistance which is developed on the ends and sides of the train when wind velocity is considered to be zero. It is low at lower speeds, but increases as the square of velocity as the speed increases and it is given as 0.0000006wv^2.
How to Calculate Total Train Resistance?
Total Train Resistance calculator uses Total Train Resistance = 0.0016*Weight of Train+0.00008*Weight of Train*Speed of Train+0.0000006*Weight of Train*Speed of Train^2 to calculate the Total Train Resistance, The Total train resistance is given as the combination of resistance due to Internal parts(Rt1),Resistance due to Flange Friction,Oscillations,Swaying,concussion of Bogies(Rt2) and Atmospheric Resistance(Rt3). Total Train Resistance is denoted by RT1 symbol.
How to calculate Total Train Resistance using this online calculator? To use this online calculator for Total Train Resistance, enter Weight of Train (wt) & Speed of Train (Vt) and hit the calculate button. Here is how the Total Train Resistance calculation can be explained with given input values -> 34.89278 = 0.0016*1300000+0.00008*1300000*41.3888888888889+0.0000006*1300000*41.3888888888889^2.
