Performing Random Vibration Fatigue Analysis Using Ansys Mechanical — Lesson 4

Vibration can be found everywhere in the environment, from a moving bicycle to a spacecraft in orbit. Even though the vibrations generate low stresses in the components, continuous loads often cause fatigue. As a result, it is critical to do a fatigue study to assess the damage caused by the vibrations and to compute the estimated life of the concerned part. In this video, we'll go through the importance of performing a random vibration fatigue study and how to accomplish it in Ansys Mechanical.
