No. | Formula | |
|---|---|---|
4.1 | Calculating the effective speed of the brake | |
| ||
[nB_m] = min-1 | Effective speed of the brake | |
[tn] = s | Duration of the individual travel sections with released brake | |
[nM_n] = min-1 | Motor speed of the individual travel sections with released brake | |
4.2 | Check of the effective speed of the brake | |
| ||
[nB_th_k] = min-1 | Thermal breakpoint speed of the brake, see chapter Permitted cyclic duration factor and thermal breakpoint speed | |
[fB_AH] | Application factor for taking into account the installation altitude of the brakemotor above sea level | |
4.3 | Calculating the cyclic duration factor of the brake | |
| ||
[cdfB] = % | Cyclic duration factor of the brake | |
[tn] = s | Duration of the individual travel sections with released brake | |
[ttot] = s | Duration of the entire travel cycle | |
4.4 | Check of the cyclic duration factor of the brake | |
| ||
[cdfB_per] = % | Permitted cyclic duration factor of the brake, see chapter Permitted cyclic duration factor and thermal breakpoint speed | |
