We experience random vibrations in day-to-day life, such as while traveling or from a breeze we feel on our face. To study the structures subjected to random vibrations where there is uncertainty in the loading, we utilize random vibration analysis. The input of this analysis follows a Gaussian distribution and is statistically represented as a power spectral density. Because the input is uncertain, the output of this analysis is statistical in nature as well. As a result, the directional outcomes, such as stresses, cannot be combined in the usual way; therefore correctly interpreting the results is crucial. In this video, we will discuss the importance of interpreting the results of a random vibration analysis using Ansys Mechanical correctly and how to do so.
