Moment of Inertia of Wind Turbines

Moment of Inertia of Wind Turbines

Moment of Inertia of Wind Turbines

Can anyone help me about how to calculate the moment of inertia of an object?

In my case, I want to find the moment of inertia of a 1.4 MW wind turbine rotating parts (high & low sped shafts, gearbox, generator rotor).

Thank you.

RE: Moment of Inertia of Wind Turbines

Mass moments of inertia should be easily found in any mechanical engineering textbook dealing with dynamics.  The one used in my engineering curriculum was Statics and Dynamics by J.L. Meriam.

RE: Moment of Inertia of Wind Turbines

Suggestion: There are several moments of inertia definitions and there are also moments of inertia calculated for basic geometric figures, and they are listed in tables. E.g. see reference:
Schaum's Outline Series "Theory and Problems of Engineering Mechanics," 3rd edition, by Mc Lean and Nelson (McGraw-Hill Book Company).
Chapter 16 Mass Moments of Inertia
Ix=integral of (y**2 + z**2)dm
Jo=integral of ro**2 dm = Ix+Iy
