Thin disk with hole, torque, thrust and angular velocity??

Thin disk with hole, torque, thrust and angular velocity??

Thin disk with hole, torque, thrust and angular velocity??

(OP)
Hi,

I'm working on a school project with a jet engine compressor disk, and I have to make an Ansys model of it. I'm rather new to Ansys though, and I was wondering: is there an easy way to model these three?

1. Torque experienced by disk (M) = 1 MNm (outer & inner surfaces; having problems finding out how to apply a moment on a surface..)
2. Maximum thrust (T) = 100 kN, in the z direction (when applying it on the outer surface, it always ends up being radial instead)
3. Maximum design rpm (?) = 1.5 x 10^4 rpm

And how do I set the inner surface's movement to zero? In I-deas (the program I usually use), I can select a surface, independent of the mesh, and I can't find that function in Ansys..

cheers,
Berit :)

RE: Thin disk with hole, torque, thrust and angular velocity??

Hello

Solution to your question

1)  Torque as T= Force* Distance from center.Divide this force by 2 and apply it as a couple ie 2 force same in magnitude but opposite in direction at two point on the outer circumference.

2) Thrust Convert Thrust into pressure and apply it over a particular area.

3) convert your rpm into rad/sec and apply it on the model with respect to the co-ordinate system.Check the direction of your couple from question 1 before you apply the direction of rotation.
