Calculation example
The known values are:
•
Average braking power: 144 W
•
Deceleration ramp: 2 s
•
200 brake applications per hour
Calculating the energy from the power of the deceleration ramp:

For the deceleration ramp of 2 s, you can use deceleration ramp [3] (0.2 s) in the dia-
gram. Use the characteristic curve with the shorter deceleration ramp because a
shorter deceleration ramp means more braking energy.
The diagram permits 290 J of braking energy for the 0.2 s deceleration ramp and
200 cycles per hour. In this case, the required 288 J can be dissipated via BW1.
