This tutorial shows how to analyze normal modes on Chladni plate using Simcenter 3D. This tutorial is divided into 5 parts: 1. Background of the Chladni plate 2. How to create Chladni Plate geometry and setup FEM and SIM files 3. Mesh and assign material properties to Chladni plate 4. Apply boundary conditions to Chladni plate 5. Run and postprocess the normal mode results


Chladni Plate Background:

Ernst Chladni publicized a way of visualizing the vibration modes of a flat plate using a relatively simple experiment.

  • A thin plate with sand and ran a violin bow across the plate’s edge.
  • This excited mode shapes of the plate, resulting in the sand moving away from areas of the plate vibrating vigorously toward areas that were stationary.
  • The patterns formed on the plate allow the mode shapes to be visualized and can be rather spectacular.

It is possible to repeat this experiment in the virtual world using Finite Element Analysis in Simcenter 3D.
This tutorial shows how to perform such an analysis. In doing so, the user will be introduced to important basic concepts and the analysis methodology within Simcenter 3D.

Before starting this tutorial, it is worthwhile reading the Simcenter 3D Files and Modelling Approach for Finite Element Analysis article that explains the various file types used in Simcenter 3D and broadly outlines the analysis methodology.
