Performing Prestressed Modal Analysis Using Ansys Mechanical – Lesson 2

A modal analysis determines the vibration characteristics such as natural frequencies and mode shapes of a structure which serves as a starting point for several linear dynamic analyses. The mode frequencies and shapes depend on the distribution of mass and stiffness in the structure. In a stressed state the stiffness changes due to the stress stiffening, altering its vibration characteristics. In this video, you will see how to perform a prestressed modal analysis in Ansys Workbench. Additionally, you will see how different natures of stress (tension and compression) change the frequency. • // INTERESTED IN MORE? • Visit Ansys Innovation Courses for free courses that include videos, handouts, simulation examples with starting files, homework problems and quizzes. • Visit today → https://bit.ly/3Eo8esU • // DOWNLOAD FREE ANSYS SOFTWARE • Ansys offers free student product downloads for homework, capstone projects, student competitions, online learning and more! • Download today → https://bit.ly/32eEcuR • // QUESTIONS ABOUT THIS VIDEO OR USING ANSYS? • Get help from Ansys experts and peers through the Ansys Learning Forum.
