Equilibrium Cant Formula:
Definition: Equilibrium cant for meter gauge is the difference between the height of the outer rail and the inner rail on a curve in case of meter gauge track.
Purpose: It helps ensure safe and comfortable train operation on curved tracks by counteracting centrifugal force.
The calculator uses the formula:
Where:
Explanation: The formula calculates the ideal cant needed to balance centrifugal force with gravitational force for a given speed and curve radius.
Details: Proper cant calculation ensures passenger comfort, reduces wear on tracks and wheels, and maintains safety at high speeds.
Tips: Enter the vehicle speed in km/h, curve radius in meters, and tolerance percentage (default ±5%). All values must be > 0.
Q1: What is the typical tolerance for equilibrium cant?
A: Standard tolerance is ±5% of the calculated equilibrium cant value.
Q2: How does speed affect equilibrium cant?
A: Cant increases with the square of speed - doubling speed requires 4 times the cant.
Q3: What happens if the cant is too high or too low?
A: Too little cant causes discomfort and wheel flange wear; too much cant can derail slow-moving trains.
Q4: Why is the constant 127 used in the formula?
A: It combines unit conversions and gravitational acceleration (9.81 m/s²) into a single constant.
Q5: Does this calculator work for broad gauge tracks?
A: No, this is specifically for meter gauge (1m track width). Broad gauge uses different constants.
