Prestressed Modal Analysis

Learn "prestress modal analysis", "modal analysis" of beam along with effect of prestress on "natural frequency". Compressive stresses decreases natural frequency and tensile stresses increases natural frequency. Also learn how to use same model for different analysis. "Geometric nonlinearity" effect how to include in analysis. Identify different types of modes are lateral, longitudinal, torsional and bending "modes". compare frequencies in modal analysis and prestressed modal analysis.

Do you have any tutorial for complete NVH training?

[@SysCADTechnoSolutions]

We will upload in future. We are studying Dynamics now.

In modal analysis shows modal frequency for Ex.10,15,20hz.why not show 1,2,3,.

[@SysCADTechnoSolutions]

For this you should have very delicate structure. Such as metal wire.

[@swapnilkesare7909]

What is model scaling?

[@SysCADTechnoSolutions]

Pleased elaborate questions.
