How to Conduct Vibration Finite Element Analysis Simulations using ANSYS: A Step-by-Step Guide to Performing Accurate Modal Analysis FEA Testing in ANSYS

by Lewis Hall

Vibration is a natural phenomenon of oscillatory motion that occurs in all elastic mechanical bodies, systems or structures after initial excitation from its primary state of equilibrium. Moreover, vibration is defined as any reciprocating periodic motion about an equilibrium position that repeats itself after a set periodic length of time known as a time interval.Hence, it is a critical component of the oscillatory motions of elastic structural bodies, which are impacted by external forces. Consequently, understanding the dynamics and characteristics of vibration is critically important in engineering. The dynamics of vibration for a structure can be assessed in terms of mode shape changes and the natural frequency at each defined Normal Mode of Vibration using finite element analysis (FEA) in ANSYS. Specifically, using the Modal Analysis technique.This eBook shows you how to; Set-up an FEA analysis in ANSYS Create an accurate structural FEA model in ANSYS Add loading conditions to a structural model Create and apply an accurate FEA mesh Solve an analysis structural model Obtain results from an ANSYS analysis View the analysis results in the ANSYS Post-Processor Overall, this eBook provides a definitive step-by-step walkthrough guide an FEA modal analysis in ANSYS to determine the effects of vibration on a multi-DOF structure.
