MOMENT OF INERTIA -MIDDLE SHAFT;

MOMENT OF INERTIA- HOIST SHAFT;

MOMENT OF INERTIA - GEAR SHAFT.

INPUT

MOTOR EFFICIENCY

CALCULATE EQUIVALENT MOMENT OF INERTIA;

Iequiv = Im + It*pow((GRA),2)/Eff + Ig*pow((GRA),2)*pow((GRB),2)/Eff/Eff

INPUT

GEAR ACCELERATION;

RatioGM = GRA*GRB ;

AlphaG = AccG/RadH ;

AlphaM = pow(GRA*GRB,-1)*AlphaG ;

TM1 = Iequiv*AlphaM ;

INPUT

MASS LOAD 1;

MASS LOAD 2

CALCULATE LOAD FORCES AND RESULTANT FORCE

F1 = Load1*(9.81-AccG)

F2 = Load2*(AccG + 9.81)

FRes = F2 - F1

CALCULATE HOIST TORQUE AND TOTAL TORQUE OF HOIST SECTION

TG = FRes*RadH

TM2 = TG*GRA*GRB/Eff/Eff

CALCULATE TOTAL TORQUE REQUIRED BY SYSTEM
