Maximum Load on Rail Seat Solution

STEP 0: Pre-Calculation Summary

Formula Used

Seat Load = Wheel Load*Sleeper Spacing/(Section Modulus*Characteristic Length of Rail)
L_max = W_L*S/(z*I)
This formula uses 5 Variables

Variables Used

Seat Load - (Measured in Newton) - Seat Load refers to the maximum allowable load on a rail seat.
Wheel Load - (Measured in Newton) - Wheel load is the part of the load of a vehicle that is carried by a single wheel and transmitted by it to the road surface.
Sleeper Spacing - (Measured in Meter) - Sleeper Spacing refers to the space between the sleepers on rail.
Section Modulus - (Measured in Cubic Meter) - Section Modulus is a geometric property for a given cross-section used in the design of beams or flexural members.
Characteristic Length of Rail - (Measured in Meter) - Characteristic Length of Rail specifies the length of the rail which is defined as ratio of stiffness and track modulus.

STEP 1: Convert Input(s) to Base Unit

Wheel Load: 43.47 Kilonewton --> 43470 Newton (Check conversion here)
Sleeper Spacing: 2.3 Meter --> 2.3 Meter No Conversion Required
Section Modulus: 0.0125 Cubic Meter --> 0.0125 Cubic Meter No Conversion Required
Characteristic Length of Rail: 16 Meter --> 16 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_max = W_L*S/(z*I) --> 43470*2.3/(0.0125*16)

Evaluating ... ...

L_max = 499905

Section Modulus of Rail given Seat Load

Go Section Modulus = (Wheel Load*Sleeper Spacing)/(Characteristic Length of Rail*Seat Load)

Characteristic Length given Seat Load on Rail

Go Characteristic Length of Rail = Wheel Load*Sleeper Spacing/(Section Modulus*Seat Load)

Maximum Load on Rail Seat

Go Seat Load = Wheel Load*Sleeper Spacing/(Section Modulus*Characteristic Length of Rail)

Sleeper Spacing given Seat Load on Rail

Go Sleeper Spacing = Section Modulus*Characteristic Length of Rail*Seat Load/Wheel Load

Wheel Load given Seat Load

Go Wheel Load = Section Modulus*Characteristic Length of Rail*Seat Load/Sleeper Spacing

Maximum Contact Shear Stress

Go Contact Shear Stress = 4.13*(Static Load/Radius of Wheel)^(1/2)

Radius of Wheel given Shear Stress

Go Radius of Wheel = (4.13/Contact Shear Stress)^(2)*Static Load

Static Wheel Load given Shear Stress

Go Static Load = (Contact Shear Stress/4.13)^2*Radius of Wheel

Maximum Load on Rail Seat Formula

Seat Load = Wheel Load*Sleeper Spacing/(Section Modulus*Characteristic Length of Rail)
L_max = W_L*S/(z*I)

What are the Lateral Forces on rails?

The Lateral Force applied to the rail head produces a lateral deflection and twist in the rail. Lateral force causes the rail to bend horizontally and the resultant torque causes a huge twist in the rail as well as the bending of the head and foot of the rail. Lateral deflection of the rail is resisted by the friction between the rail and the sleeper, the resistance offered by the rubber pad and fastenings, as well as the ballast coming in contact with the rail.
