Reply To: How to include Coriolis Effect in Static Structural to conduct pre-stressed modal of a rotor?

[sbo]

nRotating frame and stationary frame are used to make rotordynamic analysis in ansys. Ansys default option is rotating refererence frame without coriolis effect. (coriolis,on,,,off). When you open the coriolis effect in workbench, you change your frame from rotating to stationary with gyroscopic moment (Coriolis force in rotating frame). Centrifugal force does not have any effect in SRF. Please read how to derive equation of motion in stationary frame in any rotordynamic book, Therefore, when you open coriolis effect, it blocks centrifugal forces which is correct. So make you analysis without adding pres-stress due to centrifugal forces in SRF. n
