Frequency

The Frequency analysis type is used to calculate the natural frequencies of constrained or free parts and assemblies. Besides the numerical value of the eigenfrequencies, the results provide insights into the deformation behaviour of the corresponding eigenmodes. | Page 5

Modal Analysis of a cutting tool in turning

The goal is to try and make a analysis for the 3D model that the CAD designer made

Example project of a multiphysics application. A Static and a Frequency analyses are used to determine the structural behavior of the assembly. Then, a conjugate heat transfer analysis will determine the thermal behavior of the cooling process of the motor - Copy - Copy - Copy

A marimba bar's modal behaviour is governed by the shape of its undercut. The aim of this project is to show how the shape affects the modes of vibration.

The project nevertheless starts with clamped-free bars in order to show fundamental results about modal analysis.
Various effects are shown:
- Size effect of the mesh (convergence study)
- Geometry effect (length, thickness and width)
- Material effect (E/density effect)

Free-Free simulation are run with a wood bar with and without the arch.
The presence of the arch helps push back the second transverse (out-of-plane) bending mode to nearly 4 times the fundamental frequency (this is not exactly the case in this simulation because the geometry of the arch is quite arbitrary).

Improvements are underway. - Copy
