 · I modeled a large vibrating screen in ANSYS to determine the stress. I did a static model simulating the vibrations as acceleration and it was fine to find the stress. Now I need to determine the natural frequency and I found 0,739 as a result and I have no ideia if it could be wrong. What I did was just make a modal analysis. Does it seem right?

High-frequency vibrating screens - Wikipedia

In some high frequency vibrating screens the flow rate of the feed can be controlled, this is proportional to the 'popcorn effect'; if the flow rate lowers, the effect is also decreased. Limitations of the high frequency vibrating screen are that the fine screens are very fragile and are susceptible to becoming blocked very easily.

Critical speed - Wikipedia

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.
