Rotation stress
WebMar 2, 2024 · In Sect. 5.1, von Mises stress is used to analyse the mechanical stress in the rotor for different rotational speeds. The calculated deformation at the rotor surface is then compared to the measurement results of the spin test in Sect. 5.2 . WebJul 13, 2024 · Imagine that through our rotational load, we rotate that point until it is now on the y-axis. So new point is (0,1) The exaggerated displacement doesn't see it as rotation, but in terms of deltaX and deltaY (change in X, change in Y) From that we get a delta X,Y of (-1,1) Now multiply that delta by our exaggerated displacement magnification.
