Bearing and Remote Displacement (Harmonic, Modal Analysis)
Consider a Solid Shaft. I performed harmonic analysis on it. To fix ends of the shaft, I used Bearings in Case 1 and Remote displacement in case 2.
In Case 1, I inserted the plane of rotation
In case 2, I restricted every motion except the one for the rotation
But in both the cases, the answers I got in Deformation, stress were different.
Can someone explain me how and why is it so? because since both the options I used were to do same things i.e restrict particular motion and allow particular motion.
Thanks in advance.
