Simulating a shaft.

Using LTspice is it possable to simulate a shaft with or without a flywheel?
Not at all clear what you are trying to do with an electrical simulation of a mechanical device.(?)
 
There's got to be an electrical equivalent of a rotating shaft. Yes/no?
Well if it has mass, then it has inertia, so that can be simulated by an inductance.
The inertial energy of a rotating shaft is similar to the energy stored by an inductor with current going through it.
The rotational energy is:

The inductive energy is:

E = 1/2 LI²
where L= inductance
I = current

Is that what you are looking for?

That's what I am doing I am using inductors. Your equation looks to be very helpful, thank you.
 
Ages ago I simulated a DC motor by specifying the rotor's moment of inertia and using behavioural voltage sources and integration functions to represent torque, acceleration, angular velocity, back-emf.
