Homework Statement
A lot of people are familiar with equivalent inertia problems, where you have a drive train and inertia on different axis and you calculate the equivalent inertia on whichever shaft you want. This time I (try to) bring something new, trying to associate the output power to the equivalent moment of inertia on the input.
The system and the known information are shown bellow. Let's assume T1 is the driving torque and we want to get an equivalent inertia of the shafts AND the output torque T2
Homework Equations
T = I*ω
EK = (I*ω2)/2
P=T*ω
ω2*r1 = ω2*r2
The Attempt at a Solution
By means of equivalent kinetic energy, I've come to the following expression:
Ieq = I1 + I2*r1/r2 + T2*ω1/(ω2)2
I've been trying to eliminate the rotational speed in the last term.
