Sleeper Spacing given Seat Load on Rail Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Seat Load - (Measured in Kilonewton) - Seat Load refers to the maximum allowable load on a rail seat.
Wheel Load - (Measured in Kilonewton) - 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.

STEP 1: Convert Input(s) to Base Unit

Section Modulus: 0.0125 Cubic Meter --> 0.0125 Cubic Meter No Conversion Required
Characteristic Length of Rail: 16 Meter --> 16 Meter No Conversion Required
Seat Load: 500 Kilonewton --> 500 Kilonewton No Conversion Required
Wheel Load: 43.47 Kilonewton --> 43.47 Kilonewton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = z*I*L_max/W_L --> 0.0125*16*500/43.47

Evaluating ... ...

S = 2.30043708304578

STEP 3: Convert Result to Output's Unit

2.30043708304578 Meter --> No Conversion Required

FINAL ANSWER

2.30043708304578 ≈ 2.300437 Meter <-- Sleeper Spacing

Maximum Load on Rail Seat

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

Maximum Contact Shear Stress

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

Radius of Wheel given Shear Stress

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

Static Wheel Load given Shear Stress

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

Sleeper Spacing given Seat Load on Rail Formula

LaTeX Go

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

What are the Loads on Sleepers?

The Sleepers are subjected to a large number of forces such as dead and live loads, dynamic components of tracks such as rails and sleeper fastenings, maintenance standards, and other such related factors. The maximum load on the rail seat is 30 per cent-50 per cent of the dynamic wheel load, depending on various factors and especially the packing under the sleeper.
