How to perform forced vibration analysis cal using ansys

Click For Summary
SUMMARY

The discussion focuses on performing forced modal analysis of a flat rectangular plate subjected to in-plane concentrated forces using ANSYS. The user, Sagar, seeks guidance on setting up the analysis to obtain results for five modes. Key steps include creating the model, meshing, applying loads, and defining boundary conditions. The user reports that the results obtained are identical to those from a natural frequency analysis, indicating a potential setup issue.

PREREQUISITES
  • Understanding of ANSYS software for finite element analysis
  • Knowledge of modal analysis principles and techniques
  • Familiarity with meshing and boundary condition application in ANSYS
  • Concept of forced vibration analysis and its distinction from natural frequency analysis
NEXT STEPS
  • Research "ANSYS modal analysis setup for forced vibration" to understand proper configuration
  • Explore "ANSYS meshing techniques for accurate results" to improve model fidelity
  • Learn about "applying loads and boundary conditions in ANSYS" for forced modal analysis
  • Investigate "differences between natural frequency and forced modal analysis in ANSYS" to clarify results interpretation
USEFUL FOR

Mechanical engineers, students in structural analysis courses, and professionals using ANSYS for vibration analysis will benefit from this discussion.

Hi,
My problem is that I have a flat rectangular plate acted by in-plane concentrated force. I want to do the forced modal analysis for 5 modes using ansys for this plate. Can anyone tell me how to do this.

Regards,
Sagar

Welcome to the PF.

Since this is your schoolwork assignment, how about you tell us how you think you should set this up... :smile:
 
Thanks for your query.

After creating the model, meshing, applying the loads and the boundary conditions and solving using modal analysis I'm getting the results same as the one without applying any loads ( natural frequency). I'm stuck at this point. Kindly guide me through this.
