hisob-kitobi.

Harakatlanayotgan g‘ildirak chetiga bo‘lgan urinma quvvat. (urinma–egrichizikningbirornuqtasigategibo‘tganto‘grichizik)

P_k=F_kV_p/3,6 (1)
Bunda,F_k-teplovozning yuk tortish urinma kuchi, kN; 1-jadvaldan olindi;
V_p-harakat tezligi hisob-kitobi, km/s; 1-jadvadan olindi.

P_k = 255*24.5/3.6=1735.41 kVt

Kuchlanuvchi qurilmaning effektiv quvvati:

N_e=P_k/(η_perη_vspη_zp)= 1735.4/(0.975*0.836*0.84) = 2534.6 kVt

Bunda, η_per - elektr uzatishning KPDsi (Harakatning foydali koeffitsenti);
η_vsp- 0,83 – 0,85 -teplovozning o‘zi uchun ketadigan sarfni inobatga olgan holda yuk tortishga quvvatning taqsimlanishini baholash koeffitsenti;
η_zp - 0,975yuk tortish dvigatelidan tishli g‘ildiraklar juftligiga uzatishning KPD si (Harakatning foydali koeffitsenti)
Elektrik uzatishning KPDsi (Harakatning foydali koeffitsenti)(η_per)
Doimiy tok uzatishda: η_per=η_g*η_d;
O‘zgaruvchan-doimiy tok uzatishda: η_per=η_g*η_d*η_vu,
Bunda,η_g=0,93 – 0,95 - yuk tortuvchi generator KPDsi (Harakatning foydali koeffitsenti);
