Time for Retardation Solution

STEP 0: Pre-Calculation Summary
Formula Used
Time for Retardation = Crest Speed/Retardation of Train
tβ = Vm/β
This formula uses 3 Variables
Variables Used
Time for Retardation - (Measured in Second) - The Time for Retardation formula is defined as the ratio between the maximum speed (crest speed) of the train Vm and retardation of the train β .
Crest Speed - (Measured in Meter per Second) - Crest Speed is the maximum speed attained by the train during the run.
Retardation of Train - (Measured in Meter per Square Second) - Retardation of Train is the rate of change in velocity to the change in time but have negative velocity or decrease in velocity.
STEP 1: Convert Input(s) to Base Unit
Crest Speed: 98.35 Kilometer per Hour --> 27.3194444444444 Meter per Second (Check conversion ​here)
Retardation of Train: 10.36 Kilometer per Hour Second --> 2.87777777778008 Meter per Square Second (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tβ = Vm/β --> 27.3194444444444/2.87777777778008
Evaluating ... ...
tβ = 9.49324324323563
STEP 3: Convert Result to Output's Unit
9.49324324323563 Second --> No Conversion Required
FINAL ANSWER
9.49324324323563 9.493243 Second <-- Time for Retardation
(Calculation completed in 00.004 seconds)

Mechanics of Train Movement Calculators

Schedule Speed
​ Go Schedule Speed = Distance Travelled by Train/(Running Time of Train+Stop Time of Train)
Crest Speed given Time for Acceleration
​ Go Crest Speed = Time for Acceleration*Acceleration of Train
Coefficient of Adhesion
​ Go Coefficient of Adhesion = Tractive Effort/Weight of Train
Accelerating Weight of Train
​ Go Accelerating Weight of Train = Weight of Train*1.10

Electric Train Physics Calculators

Torque of Squirrel Cage Induction Motor
​ Go Torque = (Constant*Voltage^2*Rotor Resistance)/((Stator Resistance+Rotor Resistance)^2+(Stator Reactance+Rotor Reactance)^2)
Torque Generated by Scherbius Drive
​ Go Torque = 1.35*((Back Emf*AC Line Voltage*Rectified Rotor Current*RMS Value of Rotor Side Line Voltage)/(Back Emf*Angular Frequency))
Aerodynamic Drag Force
​ Go Drag Force = Drag Coefficient*((Mass Density*Flow Velocity^2)/2)*Reference Area
Accelerating Weight of Train
​ Go Accelerating Weight of Train = Weight of Train*1.10

Time for Retardation Formula

Time for Retardation = Crest Speed/Retardation of Train
tβ = Vm/β

What is Braking Retardation on suburban trains ?

Braking retardation on suburban trains is 3 to 5 km/h/sec. In suburban service, the distance between two adjacent stops for an electric train is lying between 1 and 8 km. In this service, the distance between stops is more than the urban service and smaller than the mainline service.

How to Calculate Time for Retardation?

Time for Retardation calculator uses Time for Retardation = Crest Speed/Retardation of Train to calculate the Time for Retardation, Time for Retardation formula is defined as the ratio of the crest speed Vm to the retardation of the train ( negative acceleration) β. Time for Retardation is denoted by tβ symbol.
