How's this for a start .....

Summation of Mass x Radius of Gyration^2 for all rotating parts

plus

Total Mass x Head Pulley Radius^2 for belt and handled material ???? ■

That's a very good start. Thanks, I would have had to look it up. ■

Look it up, hey it's better to start from first principles. What happens when you've lost the book?? ;-) ■

Hi Emerson..

For rotating conveyor stuff use half I Omega squared, where I is the moment of inertia of each bit, and Omega is the rotational speed in radians per second.

For the belt and material use half MV squared.

Add the two and you have the inertia of the system.

To calculate the inertia on a flywheel you need to know its moment of inertia which requires you to know its proposed geometry. Section M3 of Gieck gives you the required formulae.

Good luck
